A robotic arm using low cost 3d printed linear actuators and 3d printed parts, with optional all-metal upgrades. Most of the parts are designed to be able to be CNC plasma cut with no complex shapes or overhangs.
These are the 3d printed linear actuators I designed to drive this project. These are a low cost, easily programmed alternative to traditional linear actuators, with a small form factor. this allows all the motors to be housed within the palm of the hand.
