38、ssembly line, such as the installation of electronic components, printed circuit board. in this way, people can escape the monotony of the work stand out. robots can also remove the bomb, as the disabled person services for our community to do all kinds of work. robot is a re-programming, multi-agen

39、cy work can be pre-programmed positions in all moving parts, materials, tools or other special equipment, complete a variety of different jobs. the location is pre-programmed robot to complete the work must follow the path. in some pre-programmed location, the robot will stop some operations, such a

40、s installing parts, painting or welding. these pre-programmed location is stored in the robots memory to recall at any time of continuous operation. if the job requirements changed, the location of these pre-programmed data, together with other programming can be changed. these characteristics make

41、industrial robot programming and computer are very similar. robot system can control the robots work unit. robot work cell robots perform tasks in the work environment. unit of work, including the robot manipulator, controller, working platforms, safety equipment and gear. in addition, the robot sho

42、uld be able to communicate with the outside world signals. robot manipulator to complete the specific work of the robot system, which consists of two parts: the mechanical parts and ancillary parts. subsidiary part of the installed robot base. several fixed on the floor at the job site. but sometime

43、s the base is able to move, in this case, the base placed in orbit for the robot from one location to another location should be. subsidiary part of the robot arm. it may be a straight arm can move, it may be a hinged arm, the robot work to provide multiple axes. articulated arm that is connected to

44、 the relevant section of the arm. end of the arm with a wrist. wrist mounted on another shaft and fitted with flange root. in the flange also can be connected to different tools to complete different tasks. mechanical axis allows the robot hand in a specific area to work. this area is called the rob

45、ot unit of work, it depends on the size of the robot. if the robot the size of the increase will increase the size of the unit of work. manipulator movement control drive or drive system. they drive the state work unit in the rotation. drive system can make the electrical, hydraulic, it can be pneum
