also maybe he should get an SLA 3d printer (if he doesnt already have one), I think the added accuracy would be useful in certain cases and could make the final iterations of his projects look better
Rubber band wheels really only help with grip and the motor doesn't have much torque so rather than grip it should be harder let's say metal. Trains also use this same method to move a lot of weight with little torque
With all of the practice and knowledge you have gained, it would be great to see you reconsider the robotic ball. It was the first of your projects that I stumbled on, prompting me to subscribe.
No need for long videos filled with a ton of useless BS just to please UA-cam algorithm, you just go straight to the point, everyone understands and everyone wants to see the upcoming evolutions! Great work, you are always super creative!
I would really love to see some of these project become a series where you refine and test designs for different applications with an end goal of actually building complete prototype devices incorporating many of your designs.
I'm a big fan of your videos !! It is probably not the major problem for now but when dealing with self-balancing robots, the higher the center of gravity, the easier its is for him to maintain its equilibrium ! It is a bit counter-intuitive but think of when you are trying to balance a stick on your hand, the bigger the stick, the easier it is !
I was playing with PCBmotor at work a few years back for some interesting applications but for some reason people weren't into it; haven't revisited it since, but it's been on the list and I still account for it in some of my own designs that will eventually be prototyped. :-) Thanks for publishing your project.
i really love this guy i still remember when i stated following you when you had just a few videos and i just found them very interesting. hope you had a lot more resources so that we can see your ideas and imagination evolve much faster. best of luck mate and your videos makes my day a lot happier!!!
I've made two wheel robot once, but it was bigger. Try changing the angle of wheels - it should help with stabilisation. Wheelchairs for sports have slightly angled wheels too. Btw I love your PCBs! It's awesome you are trying to make everything small, simple and compact :)
I think it would really help to add a third really small balance wheel like a tail , that would stop the body from spinning and give the wheels more control
Great work as always, just couple of hints. The tail solution will work better than any balancing method. add that light tail again. make wheels out of PCB, it will be much better than 3D printed ones. add a rubber around those wheels to increase traction.
After seeing big hero 6 in high school I started designing my own version of micro bots that I knew how I wanted to work mechanically but couldn’t decide on different motor adaptions. This would have been a great idea
really neat idea, have you thought about making a small gear reduction to the wheel to help deal with the low motor torque? it wont go as fast but hopefully you wont be stalling the motor as much and will over all be smoother and less hard on the fittings.
So you COULD make it from metal, OR you could optimize your print geometry. Some gussets between the main platform and its "bookend" PCB motor coils to keep them from leaning in, extra thickness in the bottom of the main platform to make a "wheelie bar" somehow (maybe put a mount for a bearing, to be used as a central 3rd wheel). You could also make your print thicker, after all you are adding more weight anyway. Some thoughtfully placed thicker sections around the bottom could simultaneously reinforce the corners, and make contact with the ground to prevent flipping. A little extra bulk around the bearings wouldn't be a bad idea either.
Very cool, I wonder if you could add a third motor to act as a kind of giro to stabilise platform? Like a Segway or those boards people ride? Or maybe just a third unpowered wheel like a tricycle?
it would be interesting to have multiple coils on different pcb layer but a little bit shifted between them so it can simulate more small coils in the stator but that would imply to control these set of coils in a syncronous way
Hey, RE: the problems you've had with some of the flat pancake motors starting up. Watched some of your videos and finally hit me what the problem is, been around the early 2000s since I was last looking at these types of motors closely. Pole angle. Because these only have the 6 coils, when the opposite magnet is over the coils the force is mostly 90 degrees from the PCB, not in the rotation plane. If the rotor is not constrained well it can simply push the magnet away and put the bearing in a cocked state where the friction increases and it won't turn. Higher precision bearing or longer shaft and two bearings limit the off angle, and make it less likely to get stuck in this manner. Also look at small pulses for starting, so the tiny bit of in rotation force has a chance to act on the rotor without the coils staying energized and keeping the rotor off angle and higher friction.. The other easy fix is more poles. They are problematic motors, but were used in some of the old floppies so there are ways to make them reliable, it just takes some extra work and tricks. If you look at an old 3.5" floppy with this type of PCB motor and watch its start up on a scope it will probably give you a lot of ideas..
It's great, but it would be easier to control if you would change it into a line follower. It would make steering easier (just follow the line) and you wouldn't have to worry about balance. It clearly has enough torque to move.
Pancake pcb motor..thats awesome..i think you design 2wd...what if just 1 set put in the middle like the ordinary car toys so it can spin both wheel stable? Can't wait next project..awesome.
If you take the plastic spacer part off the header once you solder the headers on the wheels, you'll be able to solder the chassis PCB so it sits much lower. I look forward to seeing this chooch along :D
I'm not specialist but looks like this bot should have more smaller coils and more smaller magnets in wheels to prevent rotating on start. I think rotating force on the wheels will be smoother. I hope you will understand my english)
Can't wait for the next prototype

First class UA-cam Entertainment!
Mate as a graduate engineer big respect for make a channel on what you love as engineer is awesome
🙏😊
i love this guy alot because hes always straight to the point and explains in an easy and advanced way what hes doing
So, here comes a new piece of art 🤩.
Suggestion: I think addition of a rubber band on the wheels can hopefully make it work much better😅
also maybe he should get an SLA 3d printer (if he doesnt already have one), I think the added accuracy would be useful in certain cases and could make the final iterations of his projects look better
@@___echo___ Ya. I was thinking so as well😉
Rubber band wheels really only help with grip and the motor doesn't have much torque so rather than grip it should be harder let's say metal. Trains also use this same method to move a lot of weight with little torque
I’ve been doing electronics DIY for years, I have to say this PCB motor opened my eyes. Great content, thanks for sharing.
Hand soldering under a scope is very relaxing.
Genius like you are changing world
Just the name of the video was enough for me to like it. I hope this the start of a great creation! Waiting for what's next!
Tal-ostja. Keep these vids coming. The concept of the motor you are using would lend itself perfectly for sealed propellers for a mini-sub.
amazing ,one day the whole world will give attention towards PCB motors
Have watched you for only 6 months and your application gets more interesting day by day. Keep up the good work!!!!
Wow your circuits are soo well integrated! Just the best!
These little contraptions are amazing and I also find your accent to be charming! Great work and I'm so glad I subbed!
With all of the practice and knowledge you have gained, it would be great to see you reconsider the robotic ball. It was the first of your projects that I stumbled on, prompting me to subscribe.
I am working on v2 but it's still facing alot of issues which I have solved yet
Next up a Segway for ants. But seriously, interesting work!
Amazing Work And PCB Robot 👍

Big fan of your work . Awesome 👍👍👍
Can't wait for the improvised version and future robots.
Just 2k more until 100k!
You should consider adding another wheel on top that drives a small reaction wheel for stability. See if that helps
Your pcbs are a work of art ❤️
🙏
Right bro
Yay.....he's back.....most artful and informative video on UA-cam..😃😃....keep doing tinier project😊😊......eagerly waiting for part 2.........
you should use gyroscopes and a pid controller to keep the robot upright perfectly and to make it go in a straight line
Carl, your channel is underrated, this is excellent work. Very interesting projects! Greets from germany.
Great and amazing, you have lots of patience
I'm a big fan of your videos !!

This is absolutely exceptional.

Love the music. Perfect touch.
I would love to do something like this some day
Such a cool little robot, definitely could even be a marketable idea but is just plain fun regardless.
Try ordering SLS parts. Milled will come out heavier, while titanium or such 3d printed parts will do the work perfectly
I'll bet your cat loves your projects -- almost had me swipin'. Exquisite stuff, sir. Two bearings per wheel may be in the cards.
Very impressive and cool! Can’t wait to see where you go next with this project.
Super cute robot 😀👍!
You always great & excellent on your experiment, which leads to learn
Hi Carl I received the Flexible PCB (x10) i am from Singapore.-Thank you.
You would make a killer flea weight combat robot with this.
That's a fantastic idea and would make a very cool spy gadget when it works and has a camera and microphone on it. Like an FPV drone.
looks great for micro robot actuators
i really love this guy i still remember when i stated following you when you had just a few videos and i just found them very interesting. hope you had a lot more resources so that we can see your ideas and imagination evolve much faster. best of luck mate and your videos makes my day a lot happier!!!

This is the homemade future of nanites
I'm studying electronics engineering, and I wish to have the same level of innovation in electronics as you one day.
That's actually more useful than some might assume. Small spaces like conduits and vents are pretty much inaccessible to anything but a snake cam.
Speechless
Nice dude really it provokes my mind to make something
Yes yes i love all the stuff you have been doing wth flexar but the potential for pcb robots are why i am here.
A robot made exclusively out of PCB board would be cool
Great work as always, just couple of hints. The tail solution will work better than any balancing method. add that light tail again. make wheels out of PCB, it will be much better than 3D printed ones. add a rubber around those wheels to increase traction.

Great Scott.
wheels are also slipping for instant torque.
BTW, cool as always.
really neat idea, have you thought about making a small gear reduction to the wheel to help deal with the low motor torque? it wont go as fast but hopefully you wont be stalling the motor as much and will over all be smoother and less hard on the fittings.
You amaze me, good sir! I wish I can grow up and do what you do someday.
I think you are a legend
Congrats on 100K!!!

Man i love this kind of vid
Impresionante tío lo que haces eres un grande enserio
Absolutely awesome! But wouldn't everything be easier if it all was way bigger and with 4 wheels?
You smashed it 👏🏾👏🏾👏🏾
Word of the day- wobbly wheel
it would be interesting to have multiple coils on different pcb layer but a little bit shifted between them so it can simulate more small coils in the stator but that would imply to control these set of coils in a syncronous way
What an awesome build. Looking forward to the next update
Good to add gyroscope sensor to balance ❤️

great project! thanks
you really should try the Loctite GC paste. Room temperature storage, no drying out and always perfect results.
I believe you should try making wheel axes at slight angle to the main board, that would probably stabilise whole thing a little bit more.
Love the music
have you tried putting a rotor on both sides of the pcb motor, i would think a second set of coils on the back side would also help
Menakjubkan...jadi pingin tau tutorial pcb transformator/ travo
Just 5k more to reach 100k subs!!
Excellent work! I think you should consider the stability you would gain from mounting the wheels on a single straight shaft, if that is possible.
It's great, but it would be easier to control if you would change it into a line follower. It would make steering easier (just follow the line) and you wouldn't have to worry about balance. It clearly has enough torque to move.
Loved the first song! 😆
You are a genius. 🙌🏻🙌🏻

These would actually be very useful for small satellites like cubesats as gyro motors because they are very small.
Excellent!!
Make a big magnet surfes for wel,no mor vibration
nice work
waiting for next part
You are very creative 😉 and hardwork.👌👏👏👏👏👏👏👏
I hope you ,best dream.
Maybe make two of these units and connect them by a single rod and place the battery there
Very Nice
I'm not specialist but looks like this bot should have more smaller coils and more smaller magnets in wheels to prevent rotating on start. I think rotating force on the wheels will be smoother. I hope you will understand my english)
What about using stacked PCB's for the wheels with self-fusing silicone tape wrapped around them to provide grip?
Very cool idea, thanks for sharing your work
I love your works❤️
It's really amazing. Try to make a flying dron
Awesome.
