Claim 5:
6. An omni-wheel, comprising:
a shaft;
a plurality of rollers circumferentially arranged about the shaft and arranged radially outward from the shaft;
a braking system, comprising:
a plurality of braking devices arranged about the shaft, each braking device comprising:, a fluid-filled bladder, wherein the fluid-filled bladder is radially aligned with an individual roller of the plurality of rollers; and
a braking pad arranged between the fluid-filled bladder and an individual roller of the plurality of rollers;
wherein the fluid-filled bladder of the plurality of fluid-filled bladders is individually pressurized and expands radially outward when pressurized, displacing a braking pad of the plurality of braking pads radially outward to contact a roller of the plurality of rollers, thereby preventing rotation of the roller, and the fluid-filled bladder is rotatably coupled to the plurality of brake pads, such that the fluid-filled bladder remains stationary as the plurality of brake pads rotate about the shaft.
