Natural unconstrained movements obey rules different from constrained elementary movements
Published online by Cambridge University Press: 04 February 2010
Abstract
The concept of a conservative control strategy minimizing the number of degrees of freedom used is criticised with reference to 3-D simple reaching and grasping experiments. The vector error in a redundant system would not be the prime controlled variable, but rather the posture for reaching, as exemplified by nearly straight displacements in joint space as opposed to curved ones in task space.
