Robot Motion and Control presents very recent results in robot motion and control. Twenty papers have been chosen and expanded from fifty-three presented at the Fourth International Workshop on Robot Motion and Control held in Poland in June 2004. The authors of these papers have been carefully selected and represent leading institutions in this field. The following recent developments are discussed: Design of trajectory planning schemes for holonomic and nonholonomic systems with optimization of energy, torque limitations and other factors. New control algorithms for industrial robots, nonholonomic systems and legged robots.
