Claims19
A positioning system comprising:
- a body;
- a flexible band disposed at least partially in the body;
- a plurality of rollers disposed in the body and in contact with the flexible band, wherein the plurality of roller includes a first roller and a second roller, wherein the first roller and the second roller are each constrained from translation both axially and radially;
- an actuator coupled to the first roller to drive rotation of the first roller and thereby move the body, wherein the actuator is fully disposed within the first roller;
- a first arm extending axially from the first roller;
- and
- a second arm extending axially from the second roller, wherein the first and second arms are fixed to a stationary platform, such that rotation of the first roller via the actuator is configured to move the body relative to the stationary platform.
