I just want to flag this one, an arm aimed at students: the Braccio ++ kit, for an introduction to robotics, letting you lift, place, twist objects under digital control ...

But what if there was a way to bridge that gap? This robot arm guide offers a guide to building a mini robotic arm using Arduino, complete with 3D-printed parts and easy-to-follow instructions.

Renard, in addition to his work as an instructor, is a software engineer and has built a robotic arm using Arduino and Raspberry Pi, among other technologies, experience he uses in his teaching.

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.

Anyone wanting to learn more about robotics and the Arduino platform may be interested in a new mini Arduino robotic arm which has been created by Slant Robotics, called LittleArm 2C.

He calls it the Robo Marionette. He’s using a MeArm 4 DOF robotic arm, a Sensel touch interface, an Arduino Uno, and a servo shield for the Arduino to control the MeArm.
