A robotic arm is an excellent idea if you’re looking to get started with electromechanical projects. There’s linkages to design, and motors to drive, but there’s also the matter of control.

For controlling the motors, an Arduino Uno and CNC stepper shield was used. The arm is operated from a computer with a GUI written in Processing, which sends instructions to the Arduino over serial.

By harnessing the power of 3D printing, servo motors, and Arduino programming, you’ll create a robotic arm that responds to your commands through a sophisticated software interface, allowing for ...
