In order to improve the interactivity of industrial robot, this paper has designed a hand gestures recognition system for industrial robot control. The system contains two MPU6050 modules, Arduino Uno, computer and a ABB IRB 120 industry robot. Two MPU6050 modules collects the human hands movement signals which will be transmitted to Arduino Uno to process. The upper computer can receive signals processed and send commands through serial port. Also, the upper computer can send signals which include the robot movement mode parameters , speed parameters , direction parameters and so on to ABB IRB 120.Thus, the movements of the robot can be controlled by the movement of both hands where the prototypes were worn . The experimental results show that the correct rate of gesture recognition of the system higher than is 99% and the system works well, which achieves the expected purpose.
