Document Summary
Components of control system that can vary independently & that are. Degrees of freedom = many sets of muscles/joints so unlimited combination of muscles for different. Directions so control system can vary independently to do effective action. Problem of redundancy of dofs- another problem to further complicate matters. Redundancy problem = many dofs so need to select specific motor programs to make fluid action. How manage to select dofs and coordinate them. Allows us to be very flexible & adaptable in how. Motor programs = theoretical principles to solve problem. Pioneer book written in 1947 but not published until 1967 (ussr politics) Coined term bio(cid:373)echa(cid:374)ics" hypothesis presented as motor programs to solve redundancy problem. Centrally determined & pre-structured commands sent to effector. Open-loop control - feed-forward: centrally determined = decided in brain-association area, pre-structured commands = response programming. *program sent to effector system & no feedback. Input executive instructions effector output. *learn by fine-tuning motor movement from trial to trail.
