The criteria the design must met are The cables must be winded inside the robot.

For the paint roller controller, using a relay for motor control, you could also use a simple MOSFET. Using the MOSFET has an advantage that it can be triggered PWM for variable speed if needed.&nbsp;</p><img src="https://community.element14.com/aggbug?PostID=24144&AppID=374&AppType=Weblog&ContentType=0" width="1" height="1">
