Makers and electronic enthusiasts looking for a new project to keep them busy this weekend might be interested in this excellent Arduino-controlled robotic arm. This innovative project is capable ...

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.

After some experimenting, he came up with a smooth moving robot arm with four steppers controlled from an Arduino Mega and A4988 stepper motor drivers.

People can learn to control a robotic third arm using their eyes and chest muscles. Such extra limbs could become essential tools for surgeons or people working in industrial jobs, say researchers.
