French robots in Korea

[moogly2]

Hi everybody,

Rhoban Project is proud to show its humanoid robots in international expo 2012 in Korea (8 millions visitors). Rhoban Project is a group mixing academic researchers, artists and others people interested in designing robotic original creatures, especially autonomous robots, legged robots. We have designed the robot Acroban for instance, and some other ones. Please visit our show at www.rhoban-project.org/RobotsYeosu.html !

Amazing system!

I met Acroban and Olivier Ly at Inorobo and I must say that Acroban is very unique in its ability to conform with external application of forces. You can push Acroban or "pull" him for a walk and he will behave like a biological creature. There's also suspension in the robot which dampens the irritating vibrations seen in larger humanoids.

Congratulations for participating at the Korean show!

Thank you Limor !!

Nice to meet you again ! Yes, we learned a lot by setting up this system.
I just made a video of the details of the hands here:

Very Good Hands. How did you made them ? 5 Servos stretching each hard string ?

[moogly2]

Actually, 12 servos ... 2 in each finger and 2 more for lateral movement of fingers (spacing).

With that, motions are more subtle and one can not do real complex movement with only 1 degree of freedom in each finger.

To design it, I used technics that I developed myself on a base introduced by Rob Knight. The hand is mainlly done with polymorph material.

Why did you use 2 servos per DOF and not the 1-servo trick used in Inmoov ?

[moogly2]

In fact, each finger has 2 independant DOF. Actually, there are 3 DOF, but the two last ones are controlled by a single servo, while the third one has an other servo. This is very close to the human hand.

I wanted more natural motion; and this allows to do more subtle things with the hand like playing music ! Well .. I don't do that at the moment, but maybe soon Even for handling things, the motions are more flexible.

This is great ! I think i had the luck to briefly see your team at Laval Virtual 2011 using kinect and robotic arms orchestra
