Engineers at Johns Hopkins have invented a globe-shaped motor that is capable of rotating in any direction. The device, which uses electromagnets controlled by a computer, could give robotic arms ...

BALTIMORE — Engineers at Johns Hopkins University have implemented a spherical motor that can roll in any direction, rather than rotate on a single axis as conventional motors do. Spherical motors ...

Imagine a computer mouse that can push back against a user's fingers to simulate braille dots. Or a robotic arm for fine-tuning circuit boards on orbiting satellites with greater accuracy than any ...

Spherical motors and actuators represent a versatile class of devices offering rotational motion in three dimensions. Their unique geometrical configuration enables multi‐degree-of-freedom (DOF) ...

Professor Ralph Hollis invented a robot with a special motor that has a very simple drive system about a decade ago called the ballbot. Fast-forward ten years and Hollis' invention called the ...

Researchers have developed a spherical motor that may let robots loosen up. Unlike a conventional motor, which turns on an axis, the new device can rotate in any direction. As such, the globe-shaped ...

Johns Hopkins University in the US is developing a spherical stepper motor. Its stator is bowl-shaped with 16 electromagnets which interact with around 80permanent magnets in the 30cm spherical rotor.

Today’s robotic arms have limited flexibility, with many robots requiring up to six arms to achieve a complete range of motion. But now engineers at the Johns Hopkins University have laid the ...
