Duarte, Fernando B. M.Tenreiro Machado, J.

For tihs type of manipulators, the proposed kinematic control algorithms adopt generalized inverse matrices. In this line of thought, the generalized inverse control scheme is tested through several experiments that reveal the difficulties that often arise. Motivated by these problems this paper studies the chaos revealed by the kinematics trajectory planning scheme, as well as its influence on the dynamics, when controlling redundant and hyper-redundant manipulators. The results reveal several fundamental properties of the chaotic phenomena and gives a deeper insight towards the future developement of superior trajectory control algorithms.engconference object
