Basic Project: Cutting Board



Saw Stop (table saw)

My idea was to create a customizable robot that adults and kids could drive at events and demonstrations. I created a 3D printed base in which motors, batteries, motor controllers, and receivers could be inserted. Then a LEGO base plate could be glued onto the front of the base. Each part inside has a JST connector so that it can quickly be changed out for another part without soldering wires.
