In this case , our machinery will be able to solve these problems.Because it can replace us doing some dangerous operation, to replace manpower to work.Because it can replace us some dangerous operation, to replace manpower to work. We have designed the Grasping machine car that developed in the mechanization and automation of the production process and the robot van combined into one product. So that it can catch things exercise can help people complete the removal of an object or obstacle clearance work in complex terrain or harsh, dangerous environment.Grasping machine car designed primarily controlled by a wireless communication car forward, backward, or turn.by the screw rotates, driven to move up and down the screw on the nut, and then realize gripper closure through the link structure to realize grasping objects actions .Screw placed vertically, and the arm is fixed on screw nut, stepper motor driven rotary screw, nut meeting next move, the arm will move up and down, which is under the robot moves down to meet the robot grasping objects, elevated movement of the object. Turn the robot, driven by fixed-gear screw rotation middlewareimplementation. Keywords: machine car; grasping objects; screw引言随着社会的进步，社会的分工也越来越细，特别是在现代化的生产中，有的人每天就只能做着同一件事，或者是拧同个部位的某个螺母，或者是接着同一个地方的
