Sherpa Biped/Humanoid Robot - LIRMM 2009

This video presents Sherpa, a biped/humanoid robot developed at LIRMM, Montpellier, France.
Sherpa main characteristics are:
(i) Its transparent actuation. This term, taken from the haptics world, means that actuation is backdrivable (reversible) and shows low inertia. This feature provides the robot a better interaction with the outside world: Sherpa can absorb external perturbations, such as shocks when walking.
(ii) It is made with two-degree-of-freedom joints actuated in a parallel manner, which lead to more human-like performances.
The electrical motors where developed in collaboration with Erneo, a young spin-off from IES, Montpellier, France. They consist in multi-polar AC brushless motors with tremendous performance, thanks to the new technology developed by Erneo (patent pending).
The mechanical transmission relies on cables and high pitch ball screws.
