Thats crazy.

It would have been funny if the video went into some rap beat and it
started pulling of crazy flatland tricks.

Was it preprogrammed to ride a unicycle, or did they just set him on it
and off it went?

The link's not working for me... Is it the same unicycling robot as
'this one' (http://tinyurl.com/4vfocj)? (probably not, since it's from
the 90s...)

The Hoovers made a unicycling robot about 17 years ago.

His name's Beau. He can climb any hill. Steeper than you could walk.
Backwards, even.

He does it so fast it can't even be caught on camera... we've tried.

'here's' (http://tinyurl.com/43mp6d) a non-video version... the robot
can't turn or freemount though.

Hopefully they'll develop her far enough to thrash her 'brother' in
races (he's got a bike) and a voice chip would sort out rude comments
from other robots...

Cool thread. Two unicycling robot videos in one day! I hadn't see/heard
of either before. Looks like they are more concerned with working out
the fore-aft balance than worrying about making turns though.

Every other unicycling bot I've seen has either had a really wide
wheel, been a monocycle or otherwise not been such a feat of balancing.
That Murata one, with it's very small size, was really impressive.

But what's up with BBC having videos that don't work in Firefox (3)?
Anyone else have this problem? No video window shows up and I get a big
blank space. It worked fine in Safari though.

Ah, so it's that unicycle robot. It's very similar to 'this one'
(http://www.youtube.com/watch?v=IlMMWFwHti4) that I found online a
while ago in that it uses a wheel mounted sideways to correct for
sideways balance. It balances in about the same way that a unicyclist
would if riding on a rail.

The other one I posted further up balances by rotating a mass on the
top that allows the robot to 'twist' the wheel in relation to the mass
on top, allowing for sideways balance. I think this is more like how
an average unicyclist balances while riding... but it's probably an
interesting combination of both.

How's that?

The first one is an actual robot that rides the uni (w/ the pedals).
The other two look like they control the wheel w/ some type of gear on
the tire.

I'm thinking more rolling tricks would be easier to program, like
riding w/ one foot, gliding and coasting (looks like it already has
idling and riding backwards down).
