+tomtronic Yep this right here, thumbs up. This channel is called x robots first of all, you are only giving us exactly what it says on the tin, complainers GTFO. Secondly it is your channel and to remain motivated, consistently putting out episodes around your real life on projects that run for 48 parts +, you must have to pick engineering challenges and projects that speak to you first and foremost, James. Anyone can see that the specifics of BB8 is what is bringing you back to revise and refine the design. Not only that it is topical still with the release of the film and has a shelf life of its own with many others rushing to complete their own design right now. This does feel like one of the leaders in the field of BB8 builds. Would that be the case if you left the project for a period of time as some people are saying?
I just want to say a big thanks to you James. Been following you for a while and you inspired me to learn electronics and Arduino coding, and I'm having so much fun with making my own things.
You know, I'm currently studying to be a mechanical engineer and when I saw the finished product of this I legitimately thought "I could never make something like this. I can never be an engineer." but seeing the logic behind everything play out, it's not nearly as far off as I thought it might be, and it's really cool to learn about all this stuff now before I have to cram for an exam. Thank you for documenting these so thoroughly, it is so, so helpful. :)
I just want to say, that's the most enjoyable 24 minutes I've had in a very long time. I just found a video of you testing the bb-8 toys on Reddit and I was amazed. Then I found this, and you just got yourself a new subscriber. Very enjoyable to watch.
I don't do robotics, electronics, or cosplay of any kind, but your tenacity and ingenuity has been rather inspiring. I've not only started hand making knives (I just got a commission for a kukri!), but I've started building recurve bows and such. Not nearly as much engineering as you're doing here, but seeing you work out all the kinks and teaching yourself as you go is exactly what I needed to see to know that I could, too. Thanks!
Who is complaining about this series? As best I can tell this is classic XRobots fare. Who cares if its a 3rd generation design. You still have interesting new problems to solve, and while I can't speak for everyone, 95% of the enjoyment I get from your videos is watching how you work thru and solve them.
Ah, yes another BB-8 video! These are my favourite. The content of this video was really nice. I liked the drilling and sped up part. Can't wait to see this finished!
Everyone needs 3 axis in their ball! Keep up the great work James, really excited for where this version is going and the series as a whole has been a great insight into problem solving and the development process. Well worth watching every video of all three versions to see it happen!
been watching you since you use to cast parts from resins. When you got the 3d printers this is exactly the stuff I was waiting for not just downloading stuff from Thingiverse but actually making an engineering your own prototypes. Loving the different versions of BB 8 and I'm loving that it's showing different ways to do one.
I am enjoying your videos on your different BB8 builds very much! I imagine they are very expensive to design and build and you obviously have excellent engineering and CAD knowledge. Thanks for posting these videos!
Most inspiring your the reason im buliding a bb8 of my own ,I think yours accually looks better than the red carpet one and that was v2 cant wait to see v3
I did not look at the time before I hit play. About 16 minutes in I was expecting "Sadly that's all we have time for in this episode" When it kept going I was quite happy.
+James Bruton (XRobots) without being too fanboy ...I have so much respect for you. You have inspired me so much. Your knowledge of physics, robotics and CAD is amazing. I've always been interested but your channel has helped me commit to learning more.
I have no complaints about more of the BB-8 builds, the internal drive mechanism is an interesting challenge.

I love the new build looks so much more like a professional robot. I used the same Lazy Susan bearing in a smaller size for my robot, but for my application it has way to much play. Now I'm locking for a better replacement.
A potentiometer between the battery and whatever motor/servo you are testing would make for a good motor/servo checker with control of the power. I use a servo tester for rc planes and stuff, figured it may be a nice tool for you as well. Im loving version 3!
Have you thought of adding sped up 3d printing clips to the videos? Watching the lead stirring really made me wonder what it would be like to watch a full BB-8 part pop out of the printer at high speed!
You should fit a mini projector like the ones they sell for smart phones so you can project images through the head eye piece, it will be awesome and I know it will work...!
Have you thought about using a flywheel spinning constantly inside the ball to act as a gyro? I understand this is how the ISS stablises and much like a ball, that has nothing to "push" against either. It would hold the mechanicals within the ball level and allow the ball to be driven in all directions, not just one track. something for version 4 maybe? :D Love your projects!
One thing you may not have thought of yet. If you try tilting the spinning flywheel *gyroscopic procession* will cause the tilting effect to be applied 90 degrees later (fore/aft).
Have you thought of using two opposing flywheels? That way you can torque in either direction quite quickly while still keeping gyroscopic stability on the tilt axis. Not sure if the added complexity would be worth it but thought i would ask. As always, keep up the good work!
+James Bruton (XRobots) I was thinking two flywheels in the same plane. That way torque would only be applied when there is a difference in speeds. Even if the speeds were both zero, speeding one up would generate torque. When you want to stop the torque you would speed up the stopped one and slow down the faster one until they hit the same speed. That would at least double your torque accuracy and reaction time. Then you could decelerate them both at the same rate without applying any torque to BB8. If you needed a very high torque, you could rapidly decel one and rapidly accel the other. The spinning wheels, regardless of the speed, would also gyro stabilize the trousers axis. In BB8 v2, I would assume starting or stopping the flywheel would give you adverse yaw in other axis (specifically 90 degrees out of plane from where it was applied). A spinning flywheel (counter-rotation or otherwise) would give the trousers something to push off of.
If you want to turn a bit tighter on the go you should be able to combine the leaning with the flywheel to tighten it up. Should be simple have max lean at maybe 75% or so turning input and start feeding in flywheel control in past that?
for a tighter turning radius, maybe spinning the fly wheel in addition to tilting it at the same time could work. . . or it could be a mess. Spinning a tilted flywheel (similiar to a helicopter blade) should result in a 90° shift to where it is tilted. . . so it probably wouldn't work. hmmm, I'm confused.
Im sure you've thought of it, but id love to see a version that has full 2 directional movement inside the ball. Like with 4 wheels as contact points that can drive together to turn, or with opposites to drive in any direction (and lean by driving the wheels perpendicular to the current velocity). Alternatively, If this is not mechanically viable id love to hear why :D
Hey James, great work! Quick question, whenever you screw down pieces directly to the 3D printed pieces, how do you create threads in the 3D printed part? Threaded inserts, do you tap the plastic, captive nuts? Thanks!
Hey James Like the work.... Would Wax have been a better solution than Latex to bind the shot? Just think it would have been easier to make change as could have melted wax out easy enough. Just a thought, Keep it up,
Could you use the flywheel and trousers tilting in tandem with the droid moving forwards/backwards to decrease the turning circle. i.e. implement some mixing on the transmitter which engages the flywheel if the droid is in motion and the trousers have reached their maximum tilt rather than turn on the spot or drive in a large arc?
if the brackets are set higher than you predicted you could always reprint them to make up for the height difference just shorten them to fit the new height rather than make another part to fill in the gaps
+James Bruton (XRobots) weird thinks? like? :) yeah but there are motors so not possible this version .. don't wanna say that my mind isn't blown from you and your work 😉
I wonder if it was really worth including the flywheel feature... It did the job but wasn't a great effect IMO, 'cause to turn on the spot you had to spin up the flywheel and then stop it. My inclination after version 2 would have been to focus strictly on turning while in motion. It does limit things a bit (can only drive forward or backward from a stop) but it's good enough to get it moving around, and the effect is good as long as you don't get it stuck somewhere.
Hi James, I bought a Taz 5 pretty much entirely because of your recommendations and the awesome projects you do. It looks really fast in the footage compared to mine - is the footage sped up or are you running at higher than default settings? Thanks.
With the flywheel, what would happen if you had one section with more lead in it than the other 2? Side to side balance would be about the same, I assume, but the on the spot rotation would be slightly different. Any idea as to how much different it would be?
hey james i have a 3d print question, what is the best way to strengthen the build lines because i have had allot of instinces where they just come apart and its realy frustration.
Hey James, when initially considering your design for this version. Did you ever consider using 3 fly wheels, one for each axis? i wonder how well such an idea would work...hmm Also, is there a reason you use ABS over PLA?
Isn't it a possibility to turn the flywheel while you're driving. The force that it will require to start up might make the turning circle slightly smaller.
+James Bruton (XRobots) Yes, there. I have not worked with this kind of material , but I think it's like a bicycle bearings , if the balls are exposed can get away . I am right?.
+James Bruton (XRobots) Ok, thank you so much for the explanation. Wait to see your next video, this version 3 promises a lot. P.S: I imagine a version 4 with artificial intelligence. It would be awesome.
James what spec laptop/desktop are you using? I'm using the latest version of 123d Design and it's suprisingly sluggish, and yet I am on a fairly powerful i7/ssd laptop (bought for work at this spec, runs other 3d programs well etc. ) Has 123d always been smooth for you? Ever come across lagging with any versions etc?
+James Bruton (XRobots) above a certain RPM it would push 90 degrees like any gyroscope .. placing a significant weight on a course screw and winding it from one side to the other would better induce a lean .. since he'll need ballast.. he could use that if he needed more lean than the head will give.. 6kilos.. err.. WONT need a ballast .. edit.. oops.. wrong person.. lol .. replace "he" with "you" .. and "you" probably have a suitable piece already designed from your ultron project.. but no space left in version 3 to use it
Maybe I've missed something, but could you explain why you used that inside axis and the big washers to hold together the inside chassis instead of just putting screw holes in the outer axis and screw it fixed? If I remember correctly the outer axis is stationery and the 'trousers' move on bearings.
Thankyou for this great episode again. for some very strange unknown reason this video does not show up on my computer. not on the playlist, not on the "all uploaded" videos etc etc. It is that I checked my youtube with my ipad that I noticed the new episode. I then again checked with my pc but nope, nothing there anywhere. I then copied the https link from my ipad to the pc and the I could watch this video from my pc. very strange. I did switch off adblocker to be sure that was not blocking somehow. same result so it seems.

I love that it's took a team of people to bring BB8 to the screen. James is one man and has built three, alone! Great work.
Don't listen to the complainers James, this is my favorite project. I'm already looking forward to version 4!
Same!
+tomtronic Same
+tomtronic Yep this right here, thumbs up. This channel is called x robots first of all, you are only giving us exactly what it says on the tin, complainers GTFO. Secondly it is your channel and to remain motivated, consistently putting out episodes around your real life on projects that run for 48 parts +, you must have to pick engineering challenges and projects that speak to you first and foremost, James. Anyone can see that the specifics of BB8 is what is bringing you back to revise and refine the design. Not only that it is topical still with the release of the film and has a shelf life of its own with many others rushing to complete their own design right now. This does feel like one of the leaders in the field of BB8 builds. Would that be the case if you left the project for a period of time as some people are saying?
you think there will be a 4th version? I think he will master it on this 3rd. I said that about the last version too though.
Another textbook instalment, James. Really enjoying this. Thanks.
I just want to say a big thanks to you James. Been following you for a while and you inspired me to learn electronics and Arduino coding, and I'm having so much fun with making my own things.
Inspirational!

your in the weapons craft! Sensei, show me your art!
James your work is ridiculously awesome! You are a BOSS at 3d printing and 123d Design and all DIY man-things .
I could watch these videos all day. Totally makes me want to learn electronics and tinker with some of my droid toys.
Awesome as always. I wanted to say that I can't wait for the finished product, but I actually like watching it come together, more...

Just as I was about to go to bed James. I'm going to be tired in the morning, but it'll be worth it.
I love getting to see your projects progress. I really appreciate you shearing them.
Man, I love seeing your projects come together.
seems to actually work waaaay better than i expected it to... looking good!
James Bruton the only machine building channel where they talk about lazy susans bannanas and trousers
I am enjoying your videos on your different BB8 builds very much! I imagine they are very expensive to design and build and you obviously have excellent engineering and CAD knowledge. Thanks for posting these videos!
Love these BB8 videos James... No objections from me, keep them coming :)
Love the plan to post-tension the axle and frame. I still want to see your BB builds take the stair test! :P
This is my favorite show to watch every week! Thank you so much James for excellent content! :)
Most inspiring your the reason im buliding a bb8 of my own ,I think yours accually looks better than the red carpet one and that was v2 cant wait to see v3
Love watching all your projects coming to life
Dont stop em coming !!! lol
I did not look at the time before I hit play. About 16 minutes in I was expecting "Sadly that's all we have time for in this episode" When it kept going I was quite happy.
James, your videos are awesome! Tank's for making them :)
he didn't make a tank
+3STUDIOS thanks* I'm sorry haha
im constantly checking for updates on this. I kinda wish i found this channel 6 months from now so i can just watch all the videos at once

Is it me, or was the sound of the lead sped up really satisfying?
+twealve dread i replayed it twice
+Superdawg FiveSixSeven yeah, Ik, it's like so cringie Ina good way!
you have weird fetishes
The amount of lead seemed a bit overkill though tbh
You should fit a mini projector like the ones they sell for smart phones so you can project images through the head eye piece, it will be awesome and I know it will work...!

This mans a damn genius.
I love the way he says aluminum.
So damn inspiring! Thanks for sharing!
I wonder if some of this work could be adapted to make a model of Serge from Caprica. Another unique looking droid.
Have you thought of using two opposing flywheels? That way you can torque in either direction quite quickly while still keeping gyroscopic stability on the tilt axis. Not sure if the added complexity would be worth it but thought i would ask.

In BB8 v2, I would assume starting or stopping the flywheel would give you adverse yaw in other axis (specifically 90 degrees out of plane from where it was applied). A spinning flywheel (counter-rotation or otherwise) would give the trousers something to push off of.
At this rate, we will soon have an army of droids.
I very like your video and I Love build ;) (sorry for my language i'm french)
Better than my French haha
Awesome I'm a fan!!!!
If you want to turn a bit tighter on the go you should be able to combine the leaning with the flywheel to tighten it up. Should be simple have max lean at maybe 75% or so turning input and start feeding in flywheel control in past that?
I'm very Impressed XRobots
If you can Build a EndoSkeleton
From You know Chucky or Freddy...
for a tighter turning radius, maybe spinning the fly wheel in addition to tilting it at the same time could work. . . or it could be a mess. Spinning a tilted flywheel (similiar to a helicopter blade) should result in a 90° shift to where it is tilted. . . so it probably wouldn't work.
hmmm, I'm confused.
***** yeah, my guts tell me the same, but it might be worth a try.
James you should do a time laps of 3d printing
This comment is going to get so many likes for no reason at all.
Don't get your hopes up...
+Joe Cyr oh no no no, thy are up, and they are high.
cannot like on phone :P
+Bradley Morris haha ya proved me wrong lol
+nickpwnes can you dislike comments?
Love ya James :D
would it be a good idea to use a bearings where the main bar the trousers are hanging on, attach to the banana?
Im sure you've thought of it, but id love to see a version that has full 2 directional movement inside the ball. Like with 4 wheels as contact points that can drive together to turn, or with opposites to drive in any direction (and lean by driving the wheels perpendicular to the current velocity). Alternatively, If this is not mechanically viable id love to hear why :D
+James Bruton (XRobots) fair enough :D maybe in version 7 you can design the ideal bb8 that surpasses the cinematic version and has full AI :P
Awesome as ever! Have you had a look at the Blynk wifi app I mentioned?
When will you be posting more R6 stuff? that was coming along great, I would love to see how it looks fully fleshed out!
***** yeah, it does make sense to wait. keep up the good work James!
Hey James, great work! Quick question, whenever you screw down pieces directly to the 3D printed pieces, how do you create threads in the 3D printed part? Threaded inserts, do you tap the plastic, captive nuts? Thanks!
brilliant
soooo good, are you planning on making this one screen accurate or are you saving that for a later version?
Hey James Like the work.... Would Wax have been a better solution than Latex to bind the shot? Just think it would have been easier to make change as could have melted wax out easy enough. Just a thought, Keep it up,
Do you think toucan run the flywheel in conjunction with the trousers to let it turn more like an aircraft would, with a slight yaw during a turn
Could you use the flywheel and trousers tilting in tandem with the droid moving forwards/backwards to decrease the turning circle. i.e. implement some mixing on the transmitter which engages the flywheel if the droid is in motion and the trousers have reached their maximum tilt rather than turn on the spot or drive in a large arc?
The cans finished reading the script for episode 7 for the first time. After, Mark Hammil pulled JJ Abrams over and said "Can I have a word?"
Cast*
Any chance of a series of 3d printing tips videos?
if the brackets are set higher than you predicted you could always reprint them to make up for the height difference just shorten them to fit the new height rather than make another part to fill in the gaps
Sir, build 600 BB8's if you must. I enjoy every video that you upload.
this is awesome!
looks so great!
well done!
so if you the flywheel would could tilt more around the radius would decrease? right?
+James Bruton (XRobots) weird thinks? like? :)
yeah but there are motors so not possible this version .. don't wanna say that my mind isn't blown from you and your work 😉

***** I guess I need to review the footage again. I don't remember it doing that.
Would using the flywheel while it's tilted possibly tighten the turn radius?
I wondered the same. I imagined difficulty in controlling.
150th view and 2nd like! (BTW its now 2:24 pm here in The Philippnes
i mean 17th like (its now 2:26 here in the Philippines)
Is there a particular reason you use a hand screwdriver to put the screws in? (As opposed to a powered drill.)
Trousers, banana? I guess naming things just as hard in engineering as programming :)
+James Bruton (XRobots) www.commitstrip.com/en/2015/10/27/one-of-the-coders-hardest-problems/
Hi James, I bought a Taz 5 pretty much entirely because of your recommendations and the awesome projects you do. It looks really fast in the footage compared to mine - is the footage sped up or are you running at higher than default settings? Thanks.
+James Bruton (XRobots) Cool, thanks - I'll have to experiment.
With the flywheel, what would happen if you had one section with more lead in it than the other 2? Side to side balance would be about the same, I assume, but the on the spot rotation would be slightly different. Any idea as to how much different it would be?
Feck it, I'm printing SOMETHING now, this video has enticed me to
hey james i have a 3d print question, what is the best way to strengthen the build lines because i have had allot of instinces where they just come apart and its realy frustration.
+Matthew Barrett (Epsilon builds) XTC-3D by smooth-on would be a good alternative for pla or other filaments
Hey James, when initially considering your design for this version. Did you ever consider using 3 fly wheels, one for each axis? i wonder how well such an idea would work...hmm
Also, is there a reason you use ABS over PLA?
Isn't it a possibility to turn the flywheel while you're driving. The force that it will require to start up might make the turning circle slightly smaller.
Did you measure the weight of each section of the flywheel to make sure it spinning in balance?
Am I the only one that wishes he'd finish his first ironman suit?
It looks great . A question , the bearings in the flywheel will be exposed or you will make a cover to prevent them get away with a strong movement?.
+James Bruton (XRobots) Yes, there. I have not worked with this kind of material , but I think it's like a bicycle bearings , if the balls are exposed can get away . I am right?.
+James Bruton (XRobots) Ok, thank you so much for the explanation. Wait to see your next video, this version 3 promises a lot.
P.S: I imagine a version 4 with artificial intelligence. It would be awesome.
+James Bruton (XRobots) when is part 5 coming out I literally can't wait
Lead Shot Latex Lasagna, Yum!
James what spec laptop/desktop are you using?
I'm using the latest version of 123d Design and it's suprisingly sluggish, and yet I am on a fairly powerful i7/ssd laptop (bought for work at this spec, runs other 3d programs well etc. )
Has 123d always been smooth for you? Ever come across lagging with any versions etc?
+James Bruton (XRobots)
Well goddamn it. haha. I'm at a loss! It's horrendous how annoying it is to design with the occasional jumps and pauses.
So are you ever going to cover that one open panel on bb-8 v2? I've skipped a few vids so I wouldn't know if you did in a previous vid :P
There's removable panels on it
so your wheel tire works as a gear? good idea
oh ok
Couldn't you combine the flywheel with the leaning to get a tighter turning radius?
Yeah, probably.
+James Bruton (XRobots) above a certain RPM it would push 90 degrees like any gyroscope .. placing a significant weight on a course screw and winding it from one side to the other would better induce a lean .. since he'll need ballast.. he could use that if he needed more lean than the head will give.. 6kilos.. err.. WONT need a ballast
.. edit.. oops.. wrong person.. lol .. replace "he" with "you" .. and "you" probably have a suitable piece already designed from your ultron project.. but no space left in version 3 to use it
James Bruton do you know where I can get your iron man CAD...? It would be super helpful
Maybe I've missed something, but could you explain why you used that inside axis and the big washers to hold together the inside chassis instead of just putting screw holes in the outer axis and screw it fixed? If I remember correctly the outer axis is stationery and the 'trousers' move on bearings.
***** I see. Well thought ahead. Thanks for answering.
Hey James, where do you buy your motors from?
Thankyou for this great episode again.
for some very strange unknown reason this video does not show up on my computer. not on the playlist, not on the "all uploaded" videos etc etc. It is that I checked my youtube with my ipad that I noticed the new episode.

How long did it take to 3D print those parts?
