Here's next week's video, early for Patrons. This one goes out publicly on Tuesday 13th July.

These are pretty good tracks and fairly simple to build, but I thought I'd add something extra to it. A four-wheel/track drive version might be interesting also.

What is a balancing Rotaped?

A few weeks ago I built a robot with ball-shaped omni-directional wheels. I've been looking another 'weird wheels' idea to build. I came across Fordson Rotaped tracks in various YouTube videos which seemed interesting. To add an extra challenge to it though I decided to make my robot balance on the two track sprockets rather than use leading or trailing wheels.

Seems like a new series, "Will it robot?!" 😄Keep up the great work.

James in the movie Big Hero 6 the character Gogo had "friction less" magnetic wheels. They are kinda like those toys that hover using magnets. Do you think you could Engineer, using electromagnets or R.E. magnets something like that?

Scott Cress

Could you build a screw tank but using a "chain" like you did here? Two cogs and a "chain" between them but the chains run like a screw along the bottom of the vehicle.

Apparently there are computer fans like that, but they don't have much load on them. I think it's going to be a complicated control project potentially to keep it 'floating in the middle' without sticking.

Yeah, but with an electromagnets can't you very the current to control the distance. Use a hall effect sensor to detect magnetic force? Just spitballing ideas.

That is fantastic! But wheeled & tracked robots aside, I have always wanted to build a flying robot, perhaps like Weebo from the movie “Flubber.” Although I don’t know if that would actually fly. Still if one started with a drone/ quadcopter, a working model of a flying robot might work. Of course that would require solving the problem of a short flight time.

awesome! looks like a star wars droid. As far as new wheel designs go, I've been thinking about the spherical wheels from the Audi rsq (featured in IRobot) and how to make them feasible. I was thinking of a fractal design when the large spherical wheel spins on smaller spheres which in turn spin on even smaller balls that can spin more freely with less friction. A 2DOF roller is also suspended on the top of the large spherical wheel in order to spin the wheel in the proper direction for steering. It might be a little hard to explain so i made a rough 3D visualization of the concept: https://pin shape.com/items/106672-3d-printed-spherical-wheel-concept (without spaces) but I'd be interested in seeing if such a spherical wheel is feasible and if could be an alternative the omnidirectional wheels you designed before

It would probably work. some commercial ball casters have a normal swivelling caster wheel above them. The other option is supporting and driving it with omni-wheels?

So cute! I think engineers don't like tracks like this because they cause large vibrations at high speed? Very interesting to watch though! I had no idea about those tractors. What about a hoverboard that uses fans and idling wheels?
