I wouldn't care if you paid me 100x as much in troll change. Go away and bring back a row of shrubs with a nice picket fence.

There aren't too many things that are really URGENT.

He's already nekid, in a bathroom - which no doubt has a floor drain somewhere. It ain't that urgent.

No deer where you live then? Shrubs are just deer fodder and a picket fence won't keep them out.

The backflip robot really was an eyeopener for me. I thought I had a reasonable feel for where technology was but once I saw that and looked at a few more vidieos I realised robotics is way, way more advanced than I had thought.  They even had half a dozen tiny robots, with a mass of just a few grams, getting enough traction to pull a car.

Did you find a solution for this? Can you share the codez, 3D print files, in fact all of your research and effort you put in (for free, naturally) and I'll replicate it and claim it as my own?

in fact all of your research
Web surfing and troll posting is research now? Not surprising.

I have 30 seconds to build a Rolls Royce from junk scrap the scrappers wouldn't take. Hellllp!

@ardly, i wonder when they are moving around how much of that is programmed movement and how much of it is reactionary...

Not the balance stuff but going straight, turning, ect, how are they deciding where it goes...

The cycling robot seems to be all based on PID loops. It was not autonomous its overall direction was controlled by radio.  It is not clear how many of the robots navigate, I think a lot of them may be like the cyclebot.
I did find one robot whose movement was entirely based on reaction motors, braking them suddenly and getting one motor to act against another.
The mechanical expertise behind these robots is amazing, I think the programming must be pretty complex as well, maybe they use neural nets and AI technigues as well as algorithms.
