Foldable 4 Wheeled Robot-Rover!

[@stevengioiosa2065]

I think the work you're doing on your channel is really well done and legitimately important. You're exposing a lot of people to an intersection of mechanical and electrical engineering that they have probably never considered. Thank you for all the work that goes into making these videos, you should be proud of yourself.

[@shyne2643]

Those motors are trash, no matter how you put it. Cool experiment but it is just not viable. just use conventional BLDC motors.

Since the day you released the first pcb motor video I have been waiting for this. It is indescribably satisfying to see this finally come to life. Amazing work as always Carl

[@Dilshad-gu7je]

I love how you document your process and share with us the failures and wrong decisions along the way. I think that by you sharing openly we learn much more from your experience. Thank you for your courage.

[@TheCebulon]

Awesome what you have achieved with these pcb motors. It is phantastic to see this.

[@colbyjohnson2344]

Very cool. Can't wait to see what you have in mind for the next version. Keep up the great work!

[@TheStuartstardust]

@Mr. Carl, please add the cam module for esp, if possible 🤞 So cool project 😎👌

[@thewatersavior]

Awesome.. V2 will be self folding ;-) !

[@Gounesh]

Can we launch our own rover to mars as a community?

[@honzas.5234]

And powered (or at least rechargeable) by a solar cell

[@TradieTrev]

Such a mad man Carl! I've never seen this type of electronic engineering in my life and you've just mastered it from true trial and error.

[@Zraeicro]

im currently very stressed because of life, and watching youtube actually helps me relax. nice video mate

[@MatthewPiercey]

Too cool! Seeing it roll across the workshop floor helps to put the tiny scale into perspective, astounding all that's packed into that little of a space. But I love the fact that it's literally a one-PCB robot. Not a robot with only one PCB, a robot that _is_ only one PCB. Motors, chassis, and all. Just wow.

[@zootflute]

You're so creative and are great at solving niche problems that could also be applied in real world applications beyond this one. I'm so excited to see where you end up

[@animememes7531]

Favourite tech youtuber, and I am not joking, you combine all the tech related things I watch, programming, mechanics, new never seen projects, and much more. I love seeing your videos, keep making these cool projects.

[@im_ricebowl]

When I was a kid, we had these magazines that had the latest news about cartoons or movies for kids. At the end of each magazine was a thin cardboard with cut outs and instructions to build a small paper robot. I hope for a day when kids can have the joy I had building small paper robots while also actually learning about circuits with the things they make especially since your project has a capability to be used for early STEM classes

[@Scott170c]

as a student that is interested in electrical engineering, your channel is one that I love to watch!

[@ettoregiuliani7034]

I like the way you are exposing your videos: from concept, through design, assembly and final testing. And how you finally make it work after a lot of struggle 😂.

[@wesselpoldervaart4658]

Omg i have been waiting for this moment ever since you started doing PCB motors

[@boira817]

You are amazing! Love your content and the way you push the limits of what can be done with just a PCB manufacturer. You are truly an inspiration to many engineers in electronics

[@Rainyjax]

It'll probably be difficult to fit in that tiny wheel, but have you tried using a Halbach array for the magnets? If you can fit it in, it might just give you the torque you need to really get it moving the way you want.

[@THE_BUDDHA]

That seems interesting. Because halbach is stronger mag field, that would increase torque?

[@THE_BUDDHA]

Excuse if that is obvious. Still a little zonked from days of relatively tough travel recently.

[@absalomdraconis]

​@@THE_BUDDHA : Yes, that would increase the torque.

[@AdityaPrakash-kt3rf]

This is a project that I never knew about but always wanted to do! Looking forward to the next version!

[@ROBO_Roundup]

Something I like about your channel is that you share your experience with us Thank you so much for your video ♥️

[@asm2750]

This is awesome. I saw a project like this done by JPL researching small space probes/rovers using flex PCBs to fold it like origami .

[@stillraven9415]

You have a unique mind. Great job.

[@iamosrazin]

nice work our student engineers in embedded systems really like your method of solving problems

[@dabocket]

your the first person i see to bake boards so casually, your the MVP

[@BrotherCreamy]

This is my favourite project of yours so far

[@lhxperimental]

You have mastered the niche of flex and rigid flex PCB. Congratulations👏

[@DMonZ1988]

this is SOOOOO COOOOOL CARL! i'm really glad you'll continue to work on it! can't wait to see where it goes. maybe you can find some off the shelf rubber bands or gaskets for the tyres that might be be more grippy and lightweight while being simpler and cheaper for you.

[@ShawnC22002]

Probably the cutest robot I’ve ever seen… Also very cool design!

[@Barnaclebeard]

PCBWay is by far my favorite KZbin advertiser. If those guys ever turn off the taps, KZbin will jump the shark.

[@joeyda3rd]

I just don't understand why this channel is not the most subscribed EE channel! Your designs are so innovative and your videos are so interesting. Maybe it's the thick accent? Whatever it is, you are doing amazing stuff, keep it up!

[@vibrion121]

Been a electronics bussiness man your project has an incredible amount of work and (re) engineering design. Congrats!

[@cobralyoner]

its really interesting following along with what you're doing with these flexible PCBs

[@AdieGood-q5g]

yeyyyy, nice 1 Mr Bugeja.....BIG up the Maltese massive!!

[@deemon710]

Ridiculously amazing work. It's incredible to see one guy have all this knowledge and drive to build a miniature little marvel. Very cool!

[@zeno2712]

Excellent! Engineering is as much about the journey towards a solution as the solution itself! Good to see the successes and not-quite-successes.

[@amandioreal2293]

Nice Engineering work and thinking. Congratulations.

[@INSIDERSTUDIO]

Improving day by day great work. Best idea for electronic projects 🎉❤❤❤

[@octoBadger]

Great stuff - very thin flexible 'fingers' or flaps on the tires would increase traction on rough surfaces I think - also the extra weight of the double lipo probably helped traction (but required more torque - trade off). Keep up the awesome work.

[@MrFranklitalien]

no jokes the coolest thing ive found all week, keep em coming

[@kquiros]

@CarlBugeja you are THE Electronics God. 🙌🏻🙌🏻

[@DmitryPodyachev]

good demo with very nice ideas and perfect implementation. Thank you for this adventure of troubleshooting !

[@vigneshs6232]

REally cool video....I think no body will do such creative ideas in such samller sizes.....Keep impressing us with your work....

[@canonicaltom]

This is amazing! I'd enjoy seeing the two side panel motors as rigid PCBs with full thickness layers.

[@jesselewis4975]

I feel like adding even really bad suspension would help a lot. The fact that it's 4 wheel drive doesn't help if less than 4 wheels are touching the ground at the same time. Super sickkk idea though. Very exciting work.

[@1minutecomicswalahollywood648]

Hello Carl, Beautiful channel and nice tutorials.

[@other_dave]

I'm constantly impressed and inspired by the creativity here, really love this project. One thing I was was thinking about was why you continued to make the wheels more or less solid when you scaled them up (I'm assuming they aren't solid infill but still). I think to get the benefit of surface area but maintain low weight you could pocket out the design and see a reasonable improvement or just print them with little to no infill. That said, I don't think that's a "cure-all". Really excited for the next video!

[@davidkempton2894]

Great work, Carl. Thanks for sharing your design development with us.

[@sambregoTT]

This is wild! Can see that as a turning point for self assembling robots and smart sand!

[@robotgrrl]

Fantastic!!! Congrats Carl on reaching this milestone!! Incredible seeing this come to fruition after all the effort you have put in over the years. Overcoming that torque hurdle will unlock even more possibilities. Way to go and keep going!

[@konradgrima2872]

Excellent educational video, you're definitely exploring the boundaries of using BLDC motors, one suggestion if I may, is to explore if possible to use a combination of BLDC and dc motors i.e. instead of using magnets try to use another pcb connected to the M board with brushes (if you can find that small) in that way you can reduce the weight & cost of the motor + Possibly achieving more torch by switching this new pcb with different voltage polarity and phase angle. Again great to see another Maltese having a top notch KZbin channel. Proset

[@guiltouf]

This project is really complex to build, and you’ve done it! Flex body, pcb motor, all wireless : amazing work Carl 👏

[@usefulelectronics]

Absolutely great Idea! I didn’t know about the 3D PCB design in Altium. Man you literally come with an invention every video:)

[@TheRainHarvester]

Inspirational! Use the same pcb coils but remove the wheels and use rubber band pulleys to gear down to smaller wheels for more torque. Could use lego to attach to your bot to a small wheel platform prototype.

[@kingmasterlord]

give this thing network access and a phone speaker, never have to show up to the office again.

[@noahspirit123]

In the future, we're gonna have cars that transforms into a house

[@JeremyCook]

So neat that you can get a foldable PCB back like that. Nice job.

[@PlayNowWorkLater]

Very cool. Thought maybe it was going to independently fold itself into shape, maybe for transportation purposes. Maybe that can be a next phase. So cool having flexible boards. Imagining the possibilities

[@devdeque7846]

[@raynca22l36]

i bet pcbway is having a blast designing these crazy pcbs

[@autonoob]

Very cool Maybe more motors could be added to increase the torque. You can perhaps put them next to the existing motors using zig-zag bends?

[@wifiguy_nz]

Love your work with micro motors and robotics.

[@theBigBlueUniverse]

Maybe adding a little elastic material to wheels for grip helps. It can help have better traction with the surface and reduce slip..

[@WestEast3259585]

I envy your dedication and consistency in exploring these sub-optimal designs, because most of them have very niche, if any, uses. However, there is no way forward and no innovation without considering non-obvious solutions.

[@Top5ListYT]

This was very interesting and satisfying to saw building a Foldable Rover.😊 Great work Carl.💯👌

[@MrJosephtrapani]

Love how creative your ideas are! Vera inspirazzjoni bro!

[@Zimmon375]

I have no clue what im talking about yet i still do. Maybe scaling everything up by like 10 to 30% could make many things easier.

[@manasbhargava2573]

Really awesome project!!

[@griffmason8591]

You could have the roof flap house extra pcb motors to layer up the motors to a thickness you can use. With a more clam shell design you could use pins again to add rigid to center with help of Aluminum Standoffs. A plugable pi cam, would be cool. As would passthough holes big enough to mount a pin on ethier side for the battery. Love the designs, i wonder if a boat would work. You got my like.

[@peter360adventures9]

Awesome. Can't wait to see more.

[@toxiccan175]

This is awesome! You have just blown my mind! Here are a few ideas for V2: - Larger body to accommodate larger motors and bigger batteries - Larger wheels to improve ability to navigate rough terrain and climb obstacles - 6 wheel design to overcome thermal constraints on motors - Small fan to improve thermal performance and allow higher voltages If anyone else has any ideas, feel free to like and comment below so he sees! :)
