A group of coworkers exploring IoT/Maker/eletronics. Uses the Particle Photon microcontroller.
A robot with two moving arms that directs a whiteboard marker around. Each arm is controlled by a servo, a third servo is used to lift the platform part that holds the arms.
Servos are bad! or rather, not so very precise in the lower price ranges. TODO, implement offset for center and factor for correcting angles.
- Particle Photon
- Three servos
- Bunch of wires
- Wood, to make platform
- Magnets, to keep platform to whiteboard
- Hinge, to allow "pen up"
- Lego, to build arms
