Some of the old timers may remember this pushbot I built a few years back.
currently repurposed as a 20 motor test jig (only an 8 motor drive at the moment).

Seems cool, but won’t the current limiting on the brain stop it from working well?
Well, guess what I might be working on
are the motors geared to 600rpm?
But… how? There are only so many amps of power on the brain. Are you modding batteries now?
The drive is all 100rpm. Two motors per wheel (with the capability to add a third on this design). The other are a mixture, in this configuration not really doing anything, but in other configurations they drive dummy loads.
That looks really cool!! How powerful do you think it will be when it will be done?
Can you put some claws on it and drive it around worlds?
The V5 battery (according to our own spec) can provide a maximum of 256W of power, that’s actually quite a lot.
Then why even bother with current limiting in the first place?

This is genius. I want one now
Yes, I remember wanting to do that in starstruck but realized It was a waste of time and a lot slower than walking. But maybe with V5 and 600 rpm motors and a 100lb kid it could be as fast as walking.
ok this is really cool.
20 v5 motors could probably theoretically carry a person at slow walking pace.
If you had multiple brains you could have even more motors and a better power distribution
Are the axles high strength?
With 20 motors this could probably carry at least 400-500 pounds, but the axles would bend a little at that kind of weight.
Ok, just to clarify, I don’t actually plan on having all 20 motors driving the wheels, at most there would be 12, 3 motors per wheel. I posted the picture just because it looks a little ridiculous with all those motors mounted on such a small robot.
It’s also not designed to carry a human…
but if anyone wan’t to build one that would be cool.
4 brains, 21x4 (84) motors (cause you don’t need a radio), $3940 + wheels and metal and you are not competing with car companies.
There will be joysticks that use potentiometers.
I really wish someone does that.
