【Abstract】 A manual force feedback controller is a key device for a master-slave manipulation system, which provides human operator’s position and orientation, velocity and force to the slave and receives force/torque from manipulator to make the operator a sense on the scene. A 6-DOF force feedback controller based on Stewart platform was designed, which consisted of a 6-DOF Stewart platform, an electro-hydraulic proportional system and a controlling and measuring system. The composition of each subsystem, the principle of force feedback and their structural feature were analyzed. The inverse solution of kinematics and the forward solution of dynamics of the platform were derived. The relationship between the structural dimensions and the performance indexes were investigated.更多还原
