Line Plotter Kit for XRP Robot

This is an adjustable pen/pencil/marker holder for the XRP Robotics Kit!

It uses an adjustable mounting mechanism for holding different sized pens and also allows for quickly swapping between them.

It's also compatible with the ultrasonic module, just make sure to lift up the plotter all the way so it doesn't interfere!
