smallest robo-one?

What's the smallest robo-one 'bot you've seen?

They all seem to be a pretty standard size, but has anyone tried mini or micro robo-one?

Maybe something like micro (http://robotdirectory.org/robot_list.cfm?cat=1&sub_cat=3)or nano (http://robotdirectory.org/robot_list.cfm?cat=1&sub_cat=18) sumo?

I have always wanted to build a miniature Robo One robot but the cost of the micro digital servos has diffused my interest until I get a job.

What about this little guy?

"Robo-One" seems to be used as a general term for bipedal robots which tends to be misleading. The Robo-One organization is focused on robot entertainment and although there are many different aspects to the competions - like walking up stairs, opening doors, and the like - the one that gets all the attention is competition in the ring. That has become the primary driving factor behind the size of the robots.

Still, the sizes vary quite a bit, as we saw clearly demonstrated at one of the competitions here in Tokyo last year-

If you broaden the definition of 'robo-one' then there are some smaller bipeds out there, like the JVC robot that's already been mentioned. It's primarily a way for JVC to show off their technology and probably won't be generally available any time soon if at all.

Beyond that, there are some tiny - really tiny biped research designs we've seen in the labs that should be unveiled later this year.

Anything futher to share on this subject? I'm looking for a small humanoid robot pattern that might be suitable for a machining project.

For now I'm considering something in the line of a Passive-Dynamic walker:

Any other ideas would be welcomed! Thanks.

Just a thought, but I recently read an article some where online that said:

"... and one can easily envision 'growing' the BRAT to include additional joints and limbs. Want to build your own Robo-One humanoid robot? Start with a BRAT and add a torso, head and arms."

:) :)

Good suggestion but it would be hard to beat the Lynxmotion SES components for that project. I was thinking more along the lines of a small, coffee table size humanoid that would feature components only available through custom machining. Something like the Parallax penguin but more humanoid.

There is one small humanoid robot that I know of. The Plen. It's not really designed to compete, but it has 18 DOF and is controlled via bluetooth phones. I saw it at the Robogames in June and was very impressed.

It's 23mm (9") tall and they call it a Desktop Hobby Robot.

I think their website even has videos of it rollerskating and riding a skateboard.

Thanks, I'd seen those videos before. Another small bot is the new HPI Racing offering, about 10" short and weighing in at about a lb. These bots are really neat but pricy.

Still looking, Harry. :)

I'm loving the Plen. Man, that's cute. I'd love to have a little army of them marching around my desk.

If we used muscle wires, how small could we get these? Probably so small we wouldn't have a power source anymore!

There's always I-Sobot http://asie.atelier.fr/upload/2007/01/omnibot2007-i-sobot-camversion.jpg
Woldrs smallest bipedal robot as close to Robo-One as you can get.
