Spherical robots comprise a class of mobile systems characterised by a fully enclosed spherical shell that integrates internal actuation mechanisms. Their dynamics are defined by complex nonholonomic ...

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) ...

Spherical roller bearings offer an unequaled combination of high load capacity, high tolerance to shock loads, and self-aligning ability, but they are speed limited. Accordingly, they are used in ...

At its core, this system developed at Yamagata University in Japan uses a "simple" cross-spherical gear paired with a monopole gear to control pitch, roll, and yaw. Essentially, the same full range of ...
