Could a robot ride a skateboard

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.

I am shocked. Wow

The inverted pendulum problem:

Im IMPRESSED!!!

I am speechless...

The assembly manual (!) 7 meg

This is fascinating...

I think this qualifies as "on topic". See him exercise (without his skin)...

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.

After seeing these posts I was ready to be impressed, but the one that got me was a video of "Murata Boy" riding a bicycle down a flat balance beam almost exactly the width of the bicycle's tires.

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.

Sounds like they belong on the Terrorist list. Fundamentalist idiots like that are a menace to Mankind. Good thing Christ gave us the Sermon on the Mount and the Beatitudes.

Why do you hate Jesus?

Hate Jesus? Why would I?

Oh, I wouldn't be at all surprised if it were actually balancing, but the algorithm isn't so terribly complex. In very broad strokes:

If accelerometer detects tilt to leff then lean to right if accelerometer detects tilt to right then lean to left etc. with forward & back.

Add some PID, and you're done. Then you can add in the leg kicks and arm waving as separate functions, and the main balancing loop will, well, balance.

There are autopiliot model helicopters that do this - I saw one on youtube that also has GPS, so you can fly it far away and push a button and it will come back to you. Again, this is very cool stuff, but with today's tools, not so very difficult to implement.

A bunch of high school kids made a segway clone a couple of years ago.

But still, it's fun to watch.

No you aren't.

I think you are right. This is from the site Roboporium:

"Plen is a small desktop toy humanoid robot that can replicate complex human movements. It is controlled remotely by use of a Bluetooth enabled phone. When programmed, it is able to use a skateboard, rollerskates, pick up, kick and throw small things, and stand up if he tumbles to the floor. It doesn't feature any sensors or automatic software reactions to certain events, as it's entirely remote-controlled."

However, they do have more advanced robots with gyros and accelerometers.

If it were that easy, I wouldn't have a full-time job.

Then try to get it working under all the circumstances that your customers expect it to, run into problems that you can't figure out because you slept through your control theory classes in school, and call me!

The Segway is just a lot more cool when Dean Kamen is talking about it.

The wide feet give it away to some extent -- they're that way for passive balance. I suspect that the skateboard doesn't turn by tilting, either.
