The iCub is a small-size humanoid robot being designed by the RobotCub Consortium, consisting of several European universities. The main goal of this platform is to study cognition through the implementation of biological motivated algorithms. This is an open project in many different ways: it will distribute its platform openly and it will develop software open-source.
