Polishing aluminium and other metals to a mirror finish is extremely labor intensive. There are several steps to the process and each requires a lot of pressure with heavy buffing equipment. Large Polishing jobs like tanker trucks or airplanes would nearly be impossible without the assistance of robotics. Our customer and RSI worked together to design an interface which enables operators to quickly polish a tanker by controlling the robots with an Xbox controller.
Hardware Selection – RSI assisted with the selection of the industrial robots required for the application payload and reach. Two X axis slides allowed the robots to traverse along both sides of the tankers. Custom Tooling was needed to mount polishing equipment and force transducers.
Application Software and HMI Development – RSI designed an intuitive user interface using an Xbox controller; enabling operators to maneuver the robot tooling across the buffing surface and around obstructions. The PC based application included a semi automatic mode where the robot would “re-trace” paths to reduce polishing time.
END OF ARM TOOLING
Constant selectable normal force at contact point (~75lbs)
Custom design changes available
Range Sensors in to aid alignment process
6-Axis Industrial Robot mounted of linear track slide to achieve full reach of one side of tanker
Multiple possible configurations to balance cost and reach
Xbox Controller For Intuitive Manual Control
Our customer chose to use and Xbox Controller for this application as opposed to a teach pendant. This decision enabled employees to rapidly learn how to control the robot.
