Design of the Operator Tracing Robot for Material Handling

Abstract

In order to improve the safety and efficiency of using material handling equipment for operators, we implemented a two-wheeled robot to assess the autonomous movement technology of the material handling equipment such as forklift, Automated Guided Vehicle(AGV) and crane. The autonomous control system requires a system that identifies the current location and direction of a robot and an operator. We implement the location of each component using the tag recognition technology which utilizes a camera. The operator can send the autonomous movement command to the robot through the Human-Machine-Interface (HMI) device, and the location of the operator and robot can be confirmed through the map information provided by the HMI device. The system collects and uses the location and direction values of the robot and the operator in real time and traces the operator when he/she moves.
