Robot Design

iCub

Before settling at its final version, the iCub head design went through several discussions and designs. One of the ideas was to have a spine like neck:


This idea was abandoned due to the control difficulties associated with it. Another idea that can give more compact and powerful designs is parallel manipulators. We did a prototype of it, here a (video) and an image




Finally the design went for a serial actuator consisting of several modules:


Videos of the first prototype: repetitive motions (stress test) (video), inertial compensation (video) and light blob tracking (video).

Better controllers were developed latter based on an optimal controller with gains obtained from child data (video,video)

Baltazar

Kinematics Properties of Baltazar
In this experiment (video) we show one of the main properties of the anthropomorphic kinematics. The position of the 3 joint and the inverse kinematics used enables the robot to orient the hand solely by setting the initial condition of the algorithm. This kind of kinematics is good to avoid obstacles.





Head Tracking the Hand

In this experiment (video) we show the coordination of the head and hand. This can be done by setting a positionning the hand and verge the eyes or by positionning the head and them move the hand to the front. Results using learning methods and algebric methods are available.

This is the development team:
