Painting robot with ‘twin’ control scheme

Arduino TeamJuly 16th, 2020

For a class project, University of Stuttgart students Ekin Sila Sahin, Lior Skoury, and Simon Treml came up with a unique painting robot named the Physical Twin.

The Physical Twin travels on a three-wheeled chassis and mounts a four-axis arm with a brush. An operator controls the arm to dip the brush into an onboard paint container, and can then manipulate it for application.

The controller consists of a joystick for movement as well as a mini version of the arm. Four potentiometers measure arm input angles, which are duplicated on four corresponding servos on the robot. A pair of Arduino Mega boards are used for the setup — one on the mobile robot and another in the remote unit.

You can see the device in action in the videos below, showing off direct operation and the ability to play back prerecorded movements.
