To get the highest possible accuracy from a welding positioner for large parts, one company turned to zero-backlash worm gears.

Why cycloidal gears? They are readily 3D printed and offer low backlash, which makes them attractive for robotic applications. There’s no need to design cycloidal gears from scratch, either.

[John Lauer] has been hard at work re-thinking robot arms. His project to create modular, open source actuators that can be connected to one another to form an arm is inspiring, and boasts an impre… ...

At MD&M West 2025, Henry Kim, a regional sales engineer at Harmonic Drive, demonstrated advancements in actuator design. Kim said that Harmonic Drive supplies the component gears that go into ...

Northwestern University researchers built low-cost, soft actuators that enable worm-like crawling robots, bicep-like lifting robots and more.

Academic Advisor: Marcin Michalowski PhD An actuator for a robotic arm was designed, based on a variable transmission gearbox utilizing a cycloidal drive. The diploma thesis included a review of ...

Supernumerary robotic limbs (SRLs) have become an effective method for assisting poststroke patients in their daily life activities. However, conventional SRLs are constrained by functionality, ...

European researchers have created a robotic arm with precise control to pick up a diverse range of objects enabled by a novel string actuator that acts as an artificial tendon.
