Abstract
Cable-suspended robots are categorized as a type of parallel manipulator that has recently attracted interest in terms of manipulation tasks. The main goal of this paper is to develop a novel mechatronic kit with a control methodology for a modularized cable-suspended robot. The advantages of such system owns modular and reconfigurable over conventional robots. In addition, position and orientation of the end-effector is forced toward the desired values by control of cable lengths. Hence, the new approach for forward and inverse kinematic calculation procedure based on the change of the cable lengths is used to measure the position and orientation of the mobile platform. Furthermore, the input shaping algorithm is implemented for point-to-point control purposes. The modified input shaping uses the s curve command (S-type) to offer superior performance than conventional trapezoidal command (T-type) in point-to-point positioning control. Experimental validation demonstrates the cable oscillation suppression effectiveness of the proposed S-type input shaping control command.
