Abstract
An omni-directional wheel includes: a center wheel configured to rotate about a first rotation axis extending in a first direction; a plurality of peripheral wheels arranged along a circumference of the center wheel and configured to rotate about a second rotation axis extending in a second direction different from the first direction; and a plurality of variable supports provided on the center wheel and configured to respectively support the plurality of peripheral wheels. At least one of the plurality of variable supports is configured to absorb, when an impact force is applied to at least one of the plurality of peripheral wheels being supported by the at least one of the plurality of variable supports, the impact by changing a distance between the center wheel and the at least one of the plurality of peripheral wheels.
