To do this, the iCub observes a human teacher drawing the shape before trying to reproduce it. The task requires a host of skills such as vision processing, imitating the teacher’s motions, practicing the drawings, exploring new actions, trajectory formation and inverse kinematics, and finally generalizing lessons learned to new tasks.
