This chapter describes how the brain forms maps of the body in relation to the internal world. It illustrates that arm movements cannot be controlled by some linear feedback mechanism. It shifts the discussion from neuroscience to robotics. This chapter shows that the force-field experiments illustrate the keen ability of the brain to deal with dynamics and with the concept of “state.” It addresses the maps that the brains must form to manipulate the environment. It introduces the concept that motor learning is a dynamical process whose state is the associated internal model of the body and its environment.

Keywords:   brain, arm movements, force-field experiments, maps, motor learning, internal model, body
