A two-dimensional electrostrictive worktable for robot precise assembly

A two-dimensional electrostrictive worktable with high precision, high response is presented. The worktable configuration, static characteristic and dynamic characteristic are described. The error analysis of the worktable is performed. The natural defects of the electrostrictive elements (hysteresis, creep) are solved. By combining the worktable with a general purpose industrial robot, a macro/micro manipulator system is developed. The hydraulic assembly experiments have been successfully performed.<
