Abstract： |
The present invention is manipulator driven with differential spring of shape memory alloy (SMA) and belongs to the field of robot technology in mechanical engineering. Technologically, the manipulator contains SMA differential spring driver and six-rod mechanism comprising mechanical finger, link rod, pull rod, block and frame. The SMA differential spring driver contains two SMA springs, and of these two SMA springs, one has one end fixed to the top board, the other has one end fixed to the pedestal and the other two ends of the two are connected to the block and are insulated each other, so as to constitute SMA differential spring driver. The six-rod mechanism has composite hinge of block, pull rod, fingers and top board. The manipulator of the present invention can complete grasping, releasing and other operation and has the advantages of simple structure, light weight, small size, low cost, etc. |
