Robonaut is the first humanoid robot ever sent into space.It is designed to look and behave much like a space-suited human. Robonaut's grasping skills and sensitivity to touch are markedly finer than those of a space-walking astronaut, because its slender fingers have no need for thick gloves. A set of 14 brushless motors in each forearm drive the hands. Robonaut's gold-plated head is articulated at the neck, allowing a similar freedom of movement to a human head. The torso is built from aluminium, with Kevlar and Teflon padding to protect it from fire and micrometeorite impacts. The torso and arms are covered with a custom-fitted fabric skin that secures the electrical wire harnesses and keeps dust away from the mechanical joints. The 'foot' is an adaptor that clicks into various attachment points on the outside of the space station, or on the end of long and similarly articulated robotic boom arms that are already part of the station's external equipment.
