Looks like it could do with a dose of actual (i.e. PDI) control.

@kevin: Don’t know how you figure that. I would have though the reaction time required is inversely proportional to the moment of inertia about the wheels. That seems intuitive anyway; I haven’t actually done the maths.

Next year’s freshman EE students at my school (MSOE) will be building their own one of these, built with the same lego pieces even i think. The EE department head showed me the one he designed last week. Looks similar to this one.

Except, it can be controlled by the accelerometer of a wii-mote :D

this one is awsome too, using ir sensor instead of compass.

and what about this one, with a rod and a pot

but this on is THE best, look him climbing the rocky mountains roads

standing is easy, more difficult is to control forward and bacward motion, and turn
btw, segway does not run alone

The feedback looks pretty unstable, and I suspect all those camera angle changes are edits hiding the times the bot falls over.

Hopefully they have success improving the software. Unfortunately one of the things DIY electronics doesn’t teach you is sound system control theory.

that’s especially impressive considering that the reaction time required to keep the thing vertical would scale linearly with its size. it’s pretty jerky, but a larger mass would damp the movements.

I don’t know if I would trust a bar2d2 with all my booze if it balanced itself on two wheels.

@unklegwar
god hackaday commentors suck.

Anyway, pretty cool project. It would be awesome to see this scaled up to a household robot – bar2-d2, or any other type of “helper” robot would benefit from such a mobility type.

Pretty awesome, but, I have to ask….

You can build a balancing robot, but can’t edit 40 seconds of blackscreen out of your video? what?

Thats pretty damn cool really.

Wonder if it could be upscaled to a full segway…

(Also looks like sometime didn’t resize their comp in after effects.)
