I’ve recently created a RUclips channel (Innovasciences) and was wondering if you knew companies who could sponsor my next video (an AI security system), as I need 40€ worth of parts. I’ve already sent about 15 emails and only two companies have replied (and won’t sponsor me).
You have gotten REALLY GOOD with your welding skills!!! I remember when you first started welding the aluminum and you were worried about how ugly they would be, but you do make some clean welds my man!!! (but it's been all aluminum.... I don't know how different welding steel really is, but I've heard man times that welding aluminum is a lot hard than steel... so that is AWESOME!)
No, James, one was a lot of work. Three is a massive effort. Three and all the rest is a mammoth project for a solo maker. Brilliant stuff and much hard work.
I built a Skutter from Red Dwarf with my partner & took it to CFZ 2024, it has appeared in a few people RUclips videos now. The parts that were expected to cause problems did but I was already prepared for that one. We used ESP NOW & it was flawless, funny thing was we were not the only ones to bring a robot, just bought the most complex robot.
Would the omniwheel work for amphibious transportation? Like driving through high water/tide by having the width of the wheels aligned with the water flow while the secondary wheels roll the vehicle across the body of water...say there is a flooded street with rapid flowing water and you needed to help someone on the other side.
I heard he is making a super weapon, something along the lines of manipulating gravity and creating a singularity. Rumors say that he is wanting to achieve it by placing together all the 3D prints he has.
This was a great James vid. It had an extensive build, it had the british flair for useless things, and then he took it to a nerd camp. Awesome. This is such a strong bot.... something tells me james should treat this like Caterpillar does an excavator, and put different kinds of tools on it. If you buy a caterpillar excavator, you can put a bucket, a skinny bucket, a jackhammer, a bucket that swivels around for the best angle, but it has hydraulics at the end of the boom, so you can do anything with it. What can James come up with to put on the end of his new tentacle? I think he could put more LED's on it and turn it into a rave bot. James could put an attachment on it, and teach it to sweep his room. I don't know, but the opportunities are endless
I just realized I've been watching your videos for 12 years now, and I still go back to that 12-year old video about coating foam with resin for my own projects. Lovely to see your journey dude!
I would LOVE to be able to go to EMF Camp!!! It looks like LOADS of fun!!! But even more I would LOVE to be able to go to Maker Fest this week :'( But I am unable to :( there are SOOOO MANY of my FAVORITE youtubers there, and SO MANY COOL PROJECTS I would LOVE to see in person!!! And honestly I would LOVE to meet you ion person James, Just so I can shake your hand and Thank You for Keeping Nerding Cool!!! If I had a 3D Printer (and a TON of filament... and apparently TONS and TONS of BEARINGS lol) I would be trying to make cool gadgets and robots, and it's all because I discovered your channel and you have shown me what's possible and just how easy it is to get to making!!! And of course there are a TON of other makers there that I would love to meet to... like SOOOOOOO MANY!!!! Oh you're so lucky you're there!! It looks like a real blast! HAVE FUN and BE SAFE!!!
You are an inspiration to me. You bring to life things that have been in my mind for years but never had the ambition to build. The build quality and time you take to make your projects is amazing. True brilliance.
one day, one of your projects will become a revolutionary new way to move people & things while forever being cemented in history. Keep up the research!
I can't believe it took me so long to find your channel. You're so dang smart and seemingly very educated. And you bring that special English tone to your videos that I think is just plain delightful. This was extremely interesting. Thank you for doing what you do.
Neat. I especially loved that you welded a frame for it. I'd love it if you incorporated welded frames into more of your robots for some extra sturdiness.
I wish I had the time and money to build something like this. Its amazing how quick you produce these massive projects. You could cover each section with a tarp or something like that to make it have some skin. Very cool project.
You should definitely do a "Behind the scenes" type of video episode where you show which projects you kept and which ones you dismantled for parts for newer projects. Even if you have a workshop, or if you do this at home. May be interesting for us who subscribe to your channel. Even if you have any exchange with other RUclipsrs in the UK or other countries
you build and get it working (sort of) so quick . it must give a lot of joy . being a bit of a perfectionist and suffering from low budgets syndrome , I think watching you is making up for a lot of mis out's . my projects mostly happen on the tabletop in a very famous abs pre fab components . kudos !
Oohh, nice seeing the lego video getting a larger scale adaptation. On a side note, I remember making a rig in Blender3D using inverse kinematics to determine the rotation. Also remember running into an issue where it would snap middle segments 180° between 2 frames. The target flat would have barely moved though, so in the sense of calculating the target positions it worked quite well. It just ignored physics. EDIT: fix typo
Would be a cool platform for some sort of programmable mobile artillery. You send a firing instruction containing some coordinates to the tentacle, it automatically drives out into the open, unfurls, moves into range, calculates trajectory and arm angle and launches some sort of projectile.
Watching and thinking what it needs is a chair on the end and there’s only one man to ride it: Colin Furze. Seems James beat me to that thought! Brilliant project and loved the night footage :)
Go with 2 mm nozzle and 2.85mm filament (or 3) and get a slicer that allows you differential printing (that is to say, allows you to print certain areas in one regime and other areas in another) so you can print the filling and non vital surfaces in speed and the vital ones slowly and with more definition. Also, the smush, set it with a credit card for maximum layer adhesion. That should give you a very strong part.
The way I handle safety is to have a constant dead man interrupt that consists of one or more encoders, or hall effect switches, on the moving parts that when activated signal an interrupt to the PWM timers that control the driven parts. The timers re-activate when a control signal comes over the link. So at every rotation or half or quarter rotation the timers shut down, the drives disable, and only enable on an active control signal. In this way there has to be active, constant input from the controller to activate the PWM timers that activate the drives, thus providing foolproof safety. If properly coded you never notice any sort of lag or indication that an active disable of the PWM signals is occurring.
What I've experienced in a form of Industrial motion control is that there's also a heartbeat signal on the command link. If you miss more than eg two consecutive heartbeat signals, drop out the motion enable relay as part of the e-stop circuit.
@@SarahB381 Then you are taking up bandwidth on the command link. There is also latency in processing those signals. On top of that if that portion of the system fails, you may still have free running timer oscillators sending control signals to the motor drivers. The key is to never have motor driver signals enabled in any state that leaves free running timers, and to disable them at the lowest latency and lowest processing level possible.
With my mech I have a dead-man interrupt built into the code: on every cycle if no input signals are detected (strings such as "Leftbicep up" or "walk forward") power is cut to the motors since all the motor controllers are wired into 2 main ones (arms & legs) that are digitally controlled.
@@Sven_Dongle I didn't say it was the only layer. It's another on top. If you're doing safety related motion control with an RC mindset, people are going to get hurt. RC radios arent a robust protocol, so if the TX disappears you need to be sure you disable the drives & go into fault. It's no use saying "but I turned the radio off, it should've been safe" if EMI causes a half rotation & you loose a finger.
Brilliant project! I was laughing because as soon as you were talking about the idea of putting a chair on it, I immediately thought of Colin Furze and then you said it. LOL!
Having one of these constructions work In The Field (literally) for days and days, instead of just enough for a couple of videos, is *amazing*. I'm curious what the inverse-kinematics equations look like for the full build, especially given that it's still hard for *humans* to control...
(this is for your last video, with the screw bike) GET RID OF THE TOGGLE SWITCH IDEA make a single forward reverse toggle, and then make left handle do a right rotation, and right handle do left rotation, like those zero-turn lawnmowers with the handles. to go forward (or backwards) twist both!
Why didn't you use nrf24l01? I lora is now my go to. Since it is wirless you could have made each stage modular with a receiver in each, and forwent the slip rings.
@@jamesbruton there are sub-ghz 433mhz 868mhz lora. Also even 2.4ghz lora is better than standard 2.4ghz since it uses Chirp-Spread-Spectrum modulation rather narrow band modulation such as Frequency-Shift-Keying. This means lora is significantly better at working at low power or in noisy environments. It is lower speed but enough for thr amount of data you're sending.
23:39 omg Harry Hill's TV Burp reference 😂 I feel like this is a very niche british pop culture reference only a handful of people will get so it makes me very happy 😆
Instead of a bunch of sticks, dials, switches etc, it would've made more sense to have a more waldo-style controller, like the one you demonstrated with Mark in the beginning; but doing some trig translation so you can use a simpler 6dof rig controller instead of having to replicate the full mechanism of the robot for the waldo.

Like maybe like a backpack kinda thing, with the tracking rig for the right arm with a squeeze thing at the end for the gripper, and a classic jetpack style arm-rest with the spacemouse for the left arm.
Does anyone know if James posted a parts list for his remote control system? I was interested that he switched to a digital signal transmission away from analog, reducing lag.
I've been working on a mini version of this as a tentacle for halloween. But I've got side-tracked by a new design for an infinitely variable transmission. One day I will finish something.

I love the video's and I'm glad to be here 2 minutes after upload!
I’ve recently created a RUclips channel (Innovasciences) and was wondering if you knew companies who could sponsor my next video (an AI security system), as I need 40€ worth of parts. I’ve already sent about 15 emails and only two companies have replied (and won’t sponsor me).
really? promoting flat earth? as someone smart enough to build a robotic tentacle and other projects?
Now coilnfiuze is gonna make that don't he??

There is only one phrase to describe James' channel. "Pure, unfiltered, uncensored child-like joy at creating things."
No, James, one was a lot of work. Three is a massive effort. Three and all the rest is a mammoth project for a solo maker. Brilliant stuff and much hard work.
I don't understand how you build bigger and bigger robots in the same time frame between videos, but this is pure awesomeness!
well it has been a few weeks
Editing
I love the way James builds a giant 2.5m tall robot only to put a tiny gripper on the end of it! 😆
The tentacle arm skipped hand day XD
🎶 most 🎶 un 🎶 der 🎶 whelm 🎶 ing 🎶 grip 🎶 per 🎶 of 🎶 the 🎶 weeeeeeek 🎶
It's weirdly cute😂
The real question is how anyone could possibly go camping WITHOUT a giant tentacle?
Obviously only posers

On a robotics point of view, it's great, but.... should have put the disco ball at the tip of the tentacle!
My favorite part is where he said "it's chassis time!" And chassised all over the place.
was he wearing a chassis-ty belt? :D
*proceeds to chassis* insparational
haha, I ruined the 69 likes
@@makeyspace no you didnt
Yes or when he sang "most underwhelming gripper of the week" really took me off guard haha
3:54 oh man, i love chassis time!
It's a GLADoS. Mount it to the ceiling! Cake!
The shoes are perfect. Maybe you could make a robot follow you in the dark by looking for those.
The speed at which you upload is actually impressive.
I always wonder how much filament and printing hours go into each project. Would be so interesting to see!
Lovely content James. And a nice documentation of EMFcamp. It's always so nice to see enthusiasts grouping together to do wonderful stuff.
The FTV footage makes it so extra worthwhile!
Gotta ❤this creature !
Your robot looks like a doctor who prop. Just needs something to cover it so it looks like there could be an alien or something inside.
You are going to need to move into a warehouse if these creations get bigger! Looks like a fun camp.
I have been watching you for years, I really hope one day you could consider teaching others or upload some courses online

It's official James is practicing to become a super villain.
I heard he is making a super weapon, something along the lines of manipulating gravity and creating a singularity. Rumors say that he is wanting to achieve it by placing together all the 3D prints he has.
It was clear when he started to make omnydirectional vehicles. This things radiates villain vibes!
That not a tentacle, it’s a genticle.
I just had to make the futurama reference. Okay I’ll see myself out.
"Okay I'll see myself out" HAHAHA.
🦀🦀🦀🦀Hooray, people are paying attention to me! 🦀🦀🦀🦀

OK. I think I'm seeing a pattern here.
When you say "Chassis time!" that's when we cue the heist-team assembly montage music. Well done!
😁
Can we see a shop/house/Old Projects tour? And do you reuse components from old projects or do you buy new every time? Awesome stuff dude. Make On
I just realized I've been watching your videos for 12 years now, and I still go back to that 12-year old video about coating foam with resin for my own projects.
Lovely to see your journey dude!
13:28 thank you for being so open about your development challenges.
Wow, best build yet!!! Loving it and what a great place to demo the machine
EMF camp looks sick. I love your shiny sweater too
Take a shot every time James says "bearings"
😮😅
15 times?
It's more fun if you pretend he's saying “bear rings”
or “1.2mm nozzle”
Very abstract and cool. Form over function can be legitimately inspiring.
I sometimes go back to your old videos, just to hear that awesome music you never play anymore..
Me too, you know where it came from because I cant find its source...
The only question I have on a project like this, "Just how many skateboard bearings did you use?"
If it takes a sponsor for such a small part, you know it's a ton.
... yes
Love the idea of these camps where curious and supportive people come together to learn, share, and dance wildly!

you should try building a ridable walking robot next, the 1.2 mm prints seem strong enough
See that one that just did a 5K? Imagine a saddle on that!
Those are much harder than you'd think: folks tend to underestimate the leverage involved in the legs. I've experienced it firsthand :D
He made an omnidirectional riding robot last time he went to this camp.
You are an inspiration to me. You bring to life things that have been in my mind for years but never had the ambition to build. The build quality and time you take to make your projects is amazing. True brilliance.
I will never understand how you manage to have such incredible output. This is SO MUCH EFFORT, and SO COOL
one day, one of your projects will become a revolutionary new way to move people & things while forever being cemented in history. Keep up the research!
"A DJ with... Owls? on his helmet making music with this pig some how without touching it" I laughed for way too long at that line
I can't believe it took me so long to find your channel. You're so dang smart and seemingly very educated. And you bring that special English tone to your videos that I think is just plain delightful. This was extremely interesting. Thank you for doing what you do.
Glad to see you used the strongest shape to build your robot.
So much electronics! Wish I knew at least 5% of his knowledge.
All I gotta say is that I'm glad you use your powers for good, and not evil.
Respect for the flickering light warning, and great project!
I don't understand how you are this productive 😅
Neat. I especially loved that you welded a frame for it. I'd love it if you incorporated welded frames into more of your robots for some extra sturdiness.

You’ve really excelled yourself with this one.
ELRS is definitely the way to go for an RC link, it's as solid as your amazing builds! 😊
Such a tremendous amount of work and knowledge!!!!!!!
1:26 1.2mm nozzle!! That's some impressive hot end and extruder on that printer!
Fantastic work done James 👍
i so love it seeing all the symetrical wire loom that are wrapped and all neat in his remote control.
I can’t believe it only took you a month to make this, literally insane
It was great seeing you at emf again! Cool robot tentacle thing!
What a beaut. This robot (with some rgb leds) would fit so well into the VIVID Sydney light festival...
Would be a cool platform for some sort of programmable mobile artillery. You send a firing instruction containing some coordinates to the tentacle, it automatically drives out into the open, unfurls, moves into range, calculates trajectory and arm angle and launches some sort of projectile.
"...an umbilical, which is just a posh word for a bit of wire." I like this guy already. ;)

is it possible to do inverse kinematic on this kind of robot
I was thinking about how, but I don't think all positions are achievable, so the controller would be quite interesting
Why didn't you use nrf24l01?

Could you do inverse kinematics on it though?

Awesome robot!
Love it! Thank you for this.
I wonder how easy it would be to set the arm up so the gripper is positionable with inverse kinematics?
man the work and trubole james goes though all for our enterteainment
Instead of a bunch of sticks, dials, switches etc, it would've made more sense to have a more waldo-style controller, like the one you demonstrated with Mark in the beginning; but doing some trig translation so you can use a simpler 6dof rig controller instead of having to replicate the full mechanism of the robot for the waldo. That's for the tentacle itself; something like a Spacemouse kinda thing would make sense to control the wheels though.
Like maybe like a backpack kinda thing, with the tracking rig for the right arm with a squeeze thing at the end for the gripper, and a classic jetpack style arm-rest with the spacemouse for the left arm.
Love it dude so cool! Great flashback to Mark's video.
James, your robot nearly took my head off.
pretty amazing you were able to field repair the robot with 3d printer
Brilliant well done mate
Amazing! I can never figure out how you can create all these projects in such short amounts of time. Do you ever sleep?
Does anyone know if James posted a parts list for his remote control system? I was interested that he switched to a digital signal transmission away from analog, reducing lag.
