Yesterday, I was practicing with a skateboard and wondering about
something. Do people know enough to program a computer, with a motion
system attached to it, to ride a skateboard?
This seems to be a far more difficult task than, say, a CNC
metalworking machine. In the CNC application, all that matters is that
the axes are moved precisely according to a pre-programmed
sequence. In the skateboarding application, precision also matters,
but it needs to react to the real time balancing situation.
To somewhat simplify this, could a robot ride a skateboard on a
surface that is well known to the robot (no need to recognize the
surface from vision sensors).
I was at a toy show in Rosemont last summer, and they had some
enthusiast club show off "Linux robots". Those robots were physically
fighting each other, in a very funny way. They looked like one year old
kids as far as their ability to move and balance was concerned.

Damage to their tailbones and skulls is much easier to repair than on
humans, who should know better if they're over, say, 20....

The answer is yes. For $2500 he can be yours.

Segway style balance detector, some drives and a small computer to tie
it all together.
Maybe Im too old..or too young. When I see good engineering of this
nature ..it gives me the warm and fuzzies.

Very cool, and very cute - you can't help but smile - but not very
complicated given the power of today's microcontrollers and the
simplicity of today's accelerometers.
But it IS very cool.
As a second thought, this robot is not really balancing, everything is
slow enough to be completely predictable. I am not quite as awed by it
as I was on my first look.
