YL-311 consists of aluminum alloy guide-rail training platform, manipulator device and control system. The training device is a coordinate manipulator, which can complete the manipulator rotation, arms up and down, horizontal arm movement, and precise control of the gripper rotates four degrees of freedom. And the transistor PLC is configured for complex position control of the whole manipulator. The control part adopts standard module design, which can be divided into power module, PLC module and system control module. It includes many technologies involved in mechatronics major, such as stepper motor drive, mechanical drive, pneumatic, PLC, sensor, etc., providing a comprehensive training environment for students, so that students can have a comprehensive understanding, training. YL-311 is mainly used for the training and assessment of electrical, electrical and electronic, automation control, electromechanical integration, is one of the best choice of training rooms construction in colleges.
