Fourteen voluntary junior elite volleyball players performed 60 jumping serve. Jumping-serve performance (JSP) as primary task and verbal reaction time (RT) to an auditory stimulus that was administered in four probe positions (PP), as secondary tas...
In this paper protraction movement, namely stepping ahead, of a three joint robot leg is optimized for energy efficiency for any given pair of initial-final tip point positions. For the optimization a modified version of gradient descent based optimal control algorithm with Hamiltonian formulation is used. The objective function is modified in steps to jump over the infeasible and inefficient l...
