Continuous finite-time control for robotic manipulators with terminal sliding mode

at - Automatisierungstechnik, 2003
A continuous finite-time control scheme for rigid robotic manipulators is proposed using a new form of terminal sliding modes. The robustness of the controller is established using the Lyapunov stability theory.

Collaborative Manipulation by Independent Manipulators

Journal of Robotics and Mechatronics, 1996
This paper shows a method to handle a target object by plural manipulators. Where, the manipulators works independently, but the target object can be driven into the specified position. The information fed to each manipulator is same, thus communication can be done by broadcasting.
