We review some general problems underlying sensorimotor transformations for biological control of limb movements. We present evidence that limb kinematics can be controlled independently of kinetics. Ill-defined inverse transformations from endpoint to joint coordinates are solved by means of kinematic constraints, such as a law of planar inter-segmental co-ordination, or by means of optimization principles. Hybrid feedback/feedforward control schemes are used whenever possible. Finally internal models mapping motor commands onto their sensory consequences and viceversa are used to improve estimates and to learn new tasks.
