Abstract
A stacking robot with multiple closed-loop subchains comprises the parallelly-connected mechanism closed-loop executing mechanism subchains and a serially-connected executing mechanism main chain. The mechanism closed-loop subchains can control a main chain connecting rod to move in a plane where a four-rod mechanism closed-loop subchain is positioned, and moving of multiple parallelly-connected connecting rod subchains and a machine body can realize space movement of a movable platform. Control on connection of multiple connecting rods and the machine body is realized through synthetic moving of the four closed-loop subchains and the machine body, and space movement of a end executer is realized. The end executer is small in movement inertia, good in kinetic performance and high in reliability, the stacking robot has the advantages of being compact in structure and simple to control, and a rod member can be made to be a light rod; the stacking robot is large in working space, so that gravity of the stacking robot is moved backwards, balance of the stacking robot is maintained, and the stacking robot can be applied to more occasions.
