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
No need for long videos filled with a ton of useless BS just to please TH-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!
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'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 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 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 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 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
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.
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 :)
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
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.
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
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
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.
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..
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.
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 TH-cam Entertainment!
Amazing Work And PCB Robot 👍
Mate as a graduate engineer big respect for make a channel on what you love as engineer is awesome
🙏😊
Hand soldering under a scope is very relaxing.
Genius like you are changing world
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
Yay.....he's back.....most artful and informative video on TH-cam..😃😃....keep doing tinier project😊😊......eagerly waiting for part 2.........
No need for long videos filled with a ton of useless BS just to please TH-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 love this guy alot because hes always straight to the point and explains in an easy and advanced way what hes doing
A robot made exclusively out of PCB board would be cool
I’ve been doing electronics DIY for years, I have to say this PCB motor opened my eyes. Great content, thanks for sharing.
This is the homemade future of nanites
Just 2k more until 100k!
amazing ,one day the whole world will give attention towards PCB motors
Super cute robot 😀👍!
Next up a Segway for ants. But seriously, interesting work!
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!
You would make a killer flea weight combat robot with this.
Just 5k more to reach 100k subs!!
Wow your circuits are soo well integrated! Just the best!
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.
These little contraptions are amazing and I also find your accent to be charming! Great work and I'm so glad I subbed!
Congrats on 100K!!!
Thanks! 😊
Nice dude really it provokes my mind to make something
Great and amazing, you have lots of patience
You always great & excellent on your experiment, which leads to learn
Have watched you for only 6 months and your application gets more interesting day by day. Keep up the good work!!!!
This is absolutely exceptional.
I'll bet your cat loves your projects -- almost had me swipin'. Exquisite stuff, sir. Two bearings per wheel may be in the cards.
Your pcbs are a work of art ❤️
🙏
Right bro
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
Hi Carl I received the Flexible PCB (x10) i am from Singapore.-Thank you.
Super cool
You smashed it 👏🏾👏🏾👏🏾
I'm a big fan of your videos !!

You are very creative 😉 and hardwork.👌👏👏👏👏👏👏👏
I hope you ,best dream.
Word of the day- wobbly wheel
looks great for micro robot actuators
Such a cool little robot, definitely could even be a marketable idea but is just plain fun regardless.
You should consider adding another wheel on top that drives a small reaction wheel for stability. See if that helps
Love the music. Perfect touch.
you should use gyroscopes and a pid controller to keep the robot upright perfectly and to make it go in a straight line
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.
Everybody gangsta until he makes millions of them and conquers the world.
I think you are a legend
Loved the first song! 😆
I would love to do something like this some day
Great Scott.
I'm studying electronics engineering, and I wish to have the same level of innovation in electronics as you one day.
You are a genius. 🙌🏻🙌🏻
Speechless
Excellent!!
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.
Yes yes i love all the stuff you have been doing wth flexar but the potential for pcb robots are why i am here.
Man i love this kind of vid
waiting for next part
Good to add gyroscope sensor to balance ❤️
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!!!
Thank you so much! I really appreciate your comment 😊
great project! thanks
Try ordering SLS parts. Milled will come out heavier, while titanium or such 3d printed parts will do the work perfectly

Really nice made! And you're almost at 100k subscribers! :) :)
Love the music
Very impressive and cool! Can’t wait to see where you go next with this project.
nice work
You amaze me, good sir! I wish I can grow up and do what you do someday.
This is so awesome
Maybe make two of these units and connect them by a single rod and place the battery there

These would actually be very useful for small satellites like cubesats as gyro motors because they are very small.

Locks like a mini hoverboard
What an awesome build. Looking forward to the next update
Cool idea 💡👍
I would suggest you 3D print entire body flat then you heat it little bit to bend it into shape.
Impresionante tío lo que haces eres un grande enserio
It's really amazing. Try to make a flying dron

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.
Nice one ..!! Keep doing we will connect sometime ...
