Abstract
A wheel assembly for a robotic cleaner may include a frame, a moveable arm pivotally coupled to the frame, a driven wheel rotatably coupled to the moveable arm such that the driven wheel pivots with the moveable arm, and a biasing mechanism configured to urge the driven wheel towards an extended position, the biasing mechanism being coupled to the frame and spaced apart from the moveable arm.
Claims19
A wheel assembly for a robotic cleaner comprising:
- a frame;
- a moveable arm pivotally coupled to the frame;
- a driven wheel rotatably coupled to the moveable arm such that the driven wheel pivots with the moveable arm;
- a pin coupled to the frame;
- and
- a torsion spring that includes a coiled portion that extends around the pin, the torsion spring configured to urge the driven wheel towards an extended position, the torsion spring being spaced apart from the moveable arm, wherein the moveable arm is configured to pivot such that a rotation axis of the driven wheel transitions between a position vertically above the pin and a position vertically below the pin.
