Its all parts are 3d printed.In Scara, the robot arm has following movements: Linear movement that allows the arm to extend and retract because of one orthogonal joint. Rotary movement at the top of the column about the shoulder joint (along vertical axis) because of one revolving joint. A selective compliance articulated robot arm (SCARA) robot is designed for small part assembly and pick-and-place applications. SCARA robots excel in repeatability and accuracy. SCARA robots require a control system, which may house all the servo amplifiers, programming logic and functional safety.
