Looking forward to how you'd complete the outer parts (sides) of the circle plus the panels.... Thank you for this video, very educating and entertaining.
You should triple the magnets and add shock absorbers to the casters or it's going to shake all the time. I've seen something similar and it shook all the time.
+James Bruton (XRobots) I remember when you were sliding the hulkbuster head mechanism, up and down repeatedly whilst staring. The look of inspiration was apparent as you stated (paraphrased) "I can make a droid frame this way !!!"
Ovation to you James!!!! How is that you are not working in the special effect industry. Do you have any formal education in engineering? How did you reach to that level of ingenuity? I love your work!
Looking cool, i love how you design all your own `mechanics and use different electronics to achieve such cool effects. This project is really coming along and i hope once its finished you'll be able to drive it all over the convention floors and amaze everyone.
This BB8 is really starting to look the part, its almost a shame you have to hide the internals! I reckon you could achieve better side to side balance using the gyroscopic precession of a servo actuated fly wheel that way you don't have to worry about rebalancing!
How would you actually overcome the issue with the magnetic interference? Does the IMU let you enable/disable each type of measurement separately or are you stuck with all three types merged? The only other thing I could think of doing would be to create some sort of concrete or plaster ring rather than using the coins.
Excellent work!! This is much more like the inner workings of BB8 as I imagined them back when he was rolled onto stage - though of course I'm not anywhere near as good with electronics as yourself . I'd love to start building things like this, hopefully one day I'll have the spare money & some experience. :D
James... Could you please, as an extra video, try to put your BB8 robot-head (the 1st bb8 you made) inside of a styrofoam hemisphere, just to see if you can control its wobble?
Hi, you said in one Video you are not considereing to use a sphere-bearing for the head-wheels, because of the noise it would make. Can´t you use instead the rubbery material for the sphere to elimate the struggle against the current wheels turning its direction. Alternatively use a steel sphere-bearing and coat the whole ball with latex to give it a softer surface (also would have more grip on sleek ground). Nice to see this interesting projects.
Hah! This is what I suggested in my reply to your first BB8 video. Obviously, you're the one who did all the hard work, but I'm happy you agreed my "pendulum drive, magnetic coupling" idea was the way to go, whether you got the idea from my comment or not. Also, how can we learn your CAD/Printing techniques? Nice involutes on your gears- very smooth. Regarding stability, instead of coins, put a LOT of mass on your pendulum/reaction wheel. Mass is your friend there.
What is the reason for the casters? if the head is tethered at absolute center, couldn't you just make the head hover over the surface of the ball, removing all surface friction?
+Reroshaggy It is an interesting line of thinking, though: since this version of BB-8 only drives in one direction (with respect to the structure of the ball), it would be possible to have an open groove in the ball and an arm that connects the inside of the ball with the outside to carry the head. Though I'm not really sure how you'd camouflage the arm and the groove. The surface details on BB-8 don't really lend themselves to hiding a groove except at one of the orange circular details, and if a head-carrying arm came out from that point in the ball it'd be way too visible.
Tetsujin I had that very same thought, and have been thinking of how it could be as you put it masked, but have yet to come up with anything. It's unfortunate as the level of control, as well as margin for failure would be improved being attached.
Hey James I know you busy with many projects now but for your next project could you build a Dalek ? as in the characters who say "EXTERMINATE" in doctor who
with regards to the head and its wheels it uses to move on the ball, have you thought about using (for lack of a better word) 'roller wheel ball'? googling the text brings up what I'm referring to, which is basically a large ball bearing trapped in a casing that is allowed to roll in any direction. I could see this may benefit the head when rotating or changing direction by making it more stable. (great channel by the way, really enjoying it)
Fantastic work! Your research and design in this project is impressive, and I like how you show, and explain to us what it is that you're doing and working with!
James, like @SoarPilot mentioned, you should integrate dual gyroscopes to stabilize your movement. Look up a Lit C-1. It's a self stabilized motorcycle that doesn't fall down even in a crash.
I think the best way to counter the wobble would be to rely less on the head's mass (which is high up and ultimately not all that heavy, going by the way you've designed it so far) and use a motorized pendulum that can manipulate a mass on a motor-driven pendulum with a lower center-of-gravity. This is more or less what you tried with the other BB-8 by using ball-bearings and water, but the issues with those is that there's no control over those, where-as with an actuated pendulum you could fine-tune it to your heart's content. You've already more-or-less done this by having the fly-wheel assembly adjust itself to compensate for some wobbling, but I think a separate pendulum assembly would offer a more fine-tuned control scheme. (just my 2 cents) Keep up the good work!
Great work so far! I have a question though. Exactly what are you planning to do to create the sphere at the bottom of BB-8 and how will it work? I have a suggestion that may work and make the sphere look good. What if you encased the drive wheel in some sort of thin, spherical casing so that the drive wheel is completely covered and looks like a solid sphere while keeping functionality. since the head is held on by the magnetic thing, it could easily go on top of this said casing and still work perfectly.
may i ask? what did you study at school? or what did you study extra to learn to do all of this? you must have a extremely high IQ? the stuff you make is epic !
Wow! great work man, this is really coming together well, and fast! when do you even sleep? "nothing worse than a droid with a slow head"..words to live by haha.
right now you have a mobile part on the inside which you use as a weight to go to either the front or the back, with a turnable ring with weights to spin. have you ever considered to make the entire rails which you use to move the weight from front to back turnable? like a circle in a circle. i don't know how to explain it really, but i could rever to a machine they use in austronaut training to prepare for 0G. a seat in a bunch of move able inner rings which are all move-able on their own axes. but instead of a seat in the center, the right you have right now?
somehow the three wheels bother me greatly both visually and functionally, have you consider using balls instead of wheels, like the old school ball point mouse, omni-directional and smooth change in directions.
With the hulk buster suit, make a pivot joint for the ankles with a hole going from the top through to the bottom that you can put a pin through. It's the easiest way of making a locking pivot joint
James, you're the man. Watching these videos I wish I had any understanding of robotics and computers. If you ever decide to sell a kit of just the robotic element in the ball I will spend an arm and a leg to get it.
Translation of the first 33 seconds: I’ve just decided to switch our Friday schedule to Monday. Which means that the test we take each Friday on what we learned during the week will now take place on Monday, before we’ve learned it. But since today is Tuesday, it doesn’t matter in the slightest. …. Pencils ready! Today we are going to learn about ………………… % - percentages
Great video, although I got some minor headaches from the designing aspects (mostly caused cause im an engineer and perfectionist,which is a really dangerous combination :P ). Here are some tips that you might want to use for this or later projects: a) If you use ball bearings then please design the fitting hole to be a bit smaller then the bearing, you can use a vice to press fit the bearings into the print => no nuts needed b) use helical or heringborne gears to eliminate the possibility of them missaligning. c) consider IGUS bushings and so on if you have parts which cause plastic to slide on plastic or metal d) You could've designed the larger gear to have it's clamping hole for the M6 rod to have a hole that's 5,2-5,5mm in diameter, that way you could screw in the threaded rod into the gear which could maybe even eliminate the need for the clamping ring. e) if possible please replace the coins with cutted round metal rods which have the according diameter and length. The metal rod could cheaply be bought from ebay and you'd eliminate the creation of an magnetic field. I know that there are often very less alternatives and in most times the alternatives are so timeconsuming, that you couldn't keep up with the video production. This is just a tiny guide of how you could improove the projects while keeping the video production going. I hope you can implement some of my ideas or comment on if you agree / disagree with me.
I am learning Arduino and when ever I get stuck on some code I watch your videos to regain my motivation. The BB-8 version 2 is a prime example of the amazing things you can do with micro controllers and a bit of code. Keep up the good work James.
Man I'm loving this project even more than the last bb-8. It's just amazing to see how everything i'm learning in collage right know being used in such a fun project. Hope I will be able to support you thru patreon in the future.
Killing it with this project. R6 was previously my favorite of your projects, but BB-8 has surpassed even it. I can't wait to see what you come up with for the utility arms.
I think you ought to consider doing BB-8 a bit like your R6 droid where it's open on the sides but still having the pop out mechanical arms and what nots. It would be a crying shame/crime to cover up all of those internal workings, they're a piece of art in themselves. ;) Also, have you considered the space below the rotating "coin ring" for help with counter balancing BB-8, or is there insufficient space in that area? Anyway, loving the progress so far, James, keep it coming!! :D
***** Ok, cool. I understand about the head movement thing, just thought having one where the head doesn't move side to side so much would be pretty neat, too. Not to worry, it'll be awesome without him showing his insides to every Tom, Dick and Harry at conventions. Glad to hear about the lead weights. I saw that part near the end and wondered if there was any electronic method to doing it.but as it turns out, some good ol' fashioned heavy weights should work just as well. ;)
I'm using your guides to design my own BB-8 project, and I've realised that electronic stability with wheels at the top is more effective than relying on weight at the bottom to stabilise it. I'm thinking that a four or eight omni-directional wheeled machine in the centre of the ball could work the best for moving the droid as it does in the movie, with no drift.
This is very impressive work! Not the type of thing I generally watch all the way through, only because of it's complexity, but you truly made it captivating. So much so that I subscribed to see this thing through. Also enjoyed the concept of the ball balancing project. It's what lead me here. You're fueling future endeavors for sure. I can already imagine where this could lead. Great job, James!!
tendrias el mejor inicio para una moto de una rueda si le das suficiente fuerza y duracion de bateria aparte de hacer un juguete de una pelicula la dirección magnetice seria fantastico seria genias que miren al futuro en ves de replicar algo
+James Bruton (XRobots) funny, because we see it as an enabler (3d printer in your case, and amateur CNC router in my case), but in the end it so barely works that we end up doing conservative stuff for everything.
it's a pretty cool project, I think it's overly complicated for what its purpose is, unless that was the whole point of this, running 3/4 wheels on the inside of a ball would have been more stable than balancing the mech. even using mechanum wheels would provide any direction of travel then as you did for the head of the mk1 build. always interesting projects though!!!
+James Bruton (XRobots) fair point! I hope the build plays out how you imagine the end result. it's looking good & is a very different approach to the same complications of such a build. good luck dude!

this will look so cool when its done
YOUR SUCH A GENEOUSE JAMES BRUTON......XD!
soo amazed by your engineering and crafting skills!! This project brings out all the best. :-D
Looking good!
Having a variant of the BB 8 with the tire body shape it has here would look really cool actually.
***** I'd love to see that. This looks really cool as it is now.
I admire what you are doing here but you seem to have a talent for over complicating a simple problem.
You should triple the magnets and add shock absorbers to the casters or it's going to shake all the time. I've seen something similar and it shook all the time.
La fuerza es intensa en ti, joven James ;)
I wondered how you'd top the R-6. It's awe inspiring.
+James Bruton (XRobots) I remember when you were sliding the hulkbuster head mechanism, up and down repeatedly whilst staring. The look of inspiration was apparent as you stated (paraphrased) "I can make a droid frame this way !!!"

Awesome

beautiful mechanism :D
the beggining explaination of the time just fucking blew my mind.
Umm... this may sound kind of dumb to ask,but why didn't you just put the ball balancing head on top? O.o
Is this really for the new star wars episode 7?
He's a goddamned timetraveler. O_o

Where did you get the joystick stick (part) ?

a gyro?
I'm a professional synthetic organic chemist. This guy makes me feel dumb.
somehow the three wheels bother me greatly both visually and functionally, have you consider using balls instead of wheels, like the old school ball point mouse, omni-directional and smooth change in directions.
I don't understand why you do not just open up a shpero BB 8 and just make a larger version of it.
With the hulk buster suit, make a pivot joint for the ankles with a hole going from the top through to the bottom that you can put a pin through. It's the easiest way of making a locking pivot joint
Lol, "plutonium and uranium are just a little bit harder to buy on eBay"
Using that technology, you could make a Gyrosphere from Jurassic World!
You mentioned 2kg to 3D print the head ... what is the approximate mass of the frame/panels of the main sphere?
You should make a darth vader cosplay it would go along great with your DIY lightsaber :D
this is fantastic! I am really excited for when the ball is a complete sphere. :)
James, you're the man. Watching these videos I wish I had any understanding of robotics and computers.
If you ever decide to sell a kit of just the robotic element in the ball I will spend an arm and a leg to get it.
There are metal gears there?! You should probably call snake to make sure you can kill it if it goes out of control
Have you thought gyros to stabilise side-to-side wobbling?
I only watch them because the things that he builds are better then the things you can buy for like £800
I had the same idea for build when I saw your BB8!! your channel is the best!
That is cool whats it made out of plz tell me.
i cnat wait util this is done, it looks so cool!
It's awesome, and i got idea you should put gopro or another camera in the sensor ,,eye".

i think wobbly head movement adds more of an atmosphere for BB. he is wobbly in the movie.
you should make a droideka built off this concept..
This is coming along great. Looks like every issue already has a solution haha. It's going to be amazing to see it fully functional.

what do you think about the hulkbuster in the new york comic con video???
Killing it with this project.
R6 was previously my favorite of your projects, but BB-8 has surpassed even it. I can't wait to see what you come up with for the utility arms.
You should program it so it decreases speed when you let go of the joystick
James, You're the best ! It's a real pleasure to follow your incredible projects.
JJ Abrams should call you for the next Star Wars ;-)
Really clever head movement mechanism, bloody awesome
could you do a give away? my mother would really want an R2D2
I think you ought to consider doing BB-8 a bit like your R6 droid where it's open on the sides but still having the pop out mechanical arms and what nots. It would be a crying shame/crime to cover up all of those internal workings, they're a piece of art in themselves. ;)

hey, what did you study in university?
Gyro sensors?
great job man that helps out alot
James, you are the master. Another great project and showcase for your problem solving skills. A superior intellect indeed!
I will say you have to use small gyro you better handled more movements
put arms on the side with nonmoterized wheels so it doesnt tip over inside the ball.
This is very impressive work! Not the type of thing I generally watch all the way through, only because of it's complexity, but you truly made it captivating.

This is looking really cool and coming along great. You're such an inventive person and I love seeing what you come up with. Keep on rolling!
shit, now I'm going to have to 3d print one myself.
The droid will be so cute being able to move its head from side to side!

why do print straight gears instead of herringbone gears? Intuitively, it doesn't make any difference when you print them, but they run better.
+James Bruton (XRobots) funny, because we see it as an enabler (3d printer in your case, and amateur CNC router in my case), but in the end it so barely works that we end up doing conservative stuff for everything.
Your RUclips channel is very inspiring! I hope one day I can create some of things you make!
when you turn the head i think it's gonna turn the big ball.
Congratulations , you are my hero , I would take your resources to test my abilities , a hug from Ecuador
it's a pretty cool project, I think it's overly complicated for what its purpose is, unless that was the whole point of this, running 3/4 wheels on the inside of a ball would have been more stable than balancing the mech. even using mechanum wheels would provide any direction of travel then as you did for the head of the mk1 build.
always interesting projects though!!!
+James Bruton (XRobots) fair point!
I hope the build plays out how you imagine the end result. it's looking good & is a very different approach to the same complications of such a build. good luck dude!
the head can't turn to fast or it will go out of sync with the motor
I guess you can say this bb-8 is the head of the world
can it move on its own and have memories like the one in the movie can
ball bearing transfers (casters)>wheel type casters .. was the decision to go with wheels based on cost$ or availability?
surely the bearing transfers would make for a smoother, more natural head movement. the wheel's aren't going to track in exact lines, now that you're using the head to stabilise, using ball transfers instead would surely take all the extra slight movements and errors out of everything as the head take the 'long way' to it's intended destination, which will cause everything else to have to adjust in return
keep the video's coming, enjoy the details of the build, would kill to have the time and money to do this
