1. An omni-wheel, comprising:
a shaft;
a plurality of rollers circumferentially arranged about the shaft and arranged radially outward from the shaft;
a braking device, comprising:
a fluid-filled bladder circumferentially arranged about the shaft; and
a plurality of braking pads arranged between the fluid-filled bladder and the plurality of rollers;
wherein the fluid-filled bladder expands radially outward when pressurized, displacing the plurality of braking pads radially outward to contact the plurality of rollers, thereby preventing rotation of the rollers, 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.
