[Tobias Kuhn] had watched a YouTube video about a robot arm which used servo motors, and wanted to try making one himself. But he found it hard to get slow or smooth movements out of the servos. Even ...

A major challenge of robotic arms is the weight of the actuators, especially closer to the end of the arm. The long lever arm means more torque is required from the other actuators, and everything ...

If you are considering building your very own robotic arm you may be interested in a new high-performance DIY robot arm built by computer scientist Pavel Surynek. The Real Robot One or RR1 has 6 (6 ...

Featured in this project is the control of a stepper motor with its speed, direction, and step size by sending some signals through the parallel port. The project provides better understanding and ...

An egg-cracking beam relies on a hyperelastic torque reversal mechanism similar to that used by mantis shrimp and jumping fleas. Credit: Seoul National University. We usually think of robots as being ...
