Thanks to 3D printing and inexpensive controllers, a robot arm doesn’t need to break the bank anymore. Case in point? [Build Some Stuff] did a good-looking compact arm with servos for under $60. The ...

[Skyentific] is looking to push the hobbyist robotics state of the art. Motors and their gears, the actuators, are typically the most expensive part. For his build, he realised he needed big servos ...

Advances in motor design have allowed different types of robots to both specialize for industrial functions and converge in precision.

Figure 2: By using smaller servo drives, robots have less dead weight to deal with, reducing their wear-and-tear. The ongoing trend of micro-sized servo drive technology is driven by Moore’s Law and ...

Texas Instruments is developing GaN power devices to enable more compact and efficient motor joints for humanoid robots.

If you are thinking of building your very own desktop robot arm and were intrigued by the project published yesterday which took you through the process of creating a mini robotic arm using Arduino.
