[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 ...

Stepper motors divide a full rotation into hundreds of discrete steps, which makes them ideal to precisely control movements, be it in cars, robots, 3D printers or CNC machines. Most stepper motors ...

The moment of truth had come for the knee-high robot standing on its improvised runway at a hotel news conference. Reporters circled it, their microphones and cameras trained on the machine as it ...

1. Joints - The Foundation of Movement Joints are the moving links in a robotic arm. They let the arm bend, rotate, or change direction-similar to how our elbows and wrists work. In a 6-axis robotic ...

Researchers teamed up to develop a machine-learning program that can be connected to a human brain and used to command a robot. The program adjusts the robot's movements based on electrical signals ...

A mechanical engineering student at Purdue University, YouTuber, and self-described robot fanatic has released details of his latest DIY robot, CARA. Unlike most robot dogs that use gears or pulleys, ...

How do you get better at making more robots? By rethinking how you build the manufacturing robots, apparently. MIT researchers have developed a minuscule "walking" motor that allows for robots which ...
