Abstract:

To solve the issue of the single ability for robot in the nuclear power plant, an autonomous exchange mechanism of the end-effector for robot is developed. The interface of multi-torque output with the concentric and parallel mechanism with 3-Hooke joints is used to provide power input for the end-effector with related operations. Based on analysis of the passive compliance and tolerance condition for the docking process of the double Hooke joints between the end-effector exchange and the tool rack, an automatic docking control strategy of the end-effectors exchange is proposed based on the contact force threshold. The automatic replacement of different end-effectors is realized by experiments, and the feasibility of the control strategy is verified. The mechanism prototype for end-effector exchange is designed. The exchange experiments of different end-effectors are carried out by the SCHUNK 6 DOF manipulator mobile experiment platform, which demonstrate the effectiveness of the control strategy, the tolerance performance of the mechanism. The experimental results show that the mechanism has completed docking process with larger tolerance compliant and realized the power transmission of the end-effector.

Key words: automation control technology, mechanical design, end-effector exchange, hooke joint, compliant docking, power transmission
