Abstract: A tool device, such as a lawnmower, or a steerable-wheel assembly therefor may include a frame, a walking element, a drive motor, and a steerable-wheel assembly (SWA). The walking element may be coupled to the frame. The drive motor may selectively power the walking element. The SWA may be attached to the frame apart from the walking element. The SWA may include a caster connector pivotably mounted to the frame to rotate about a pivot axis, a steerable wheel rotatably coupled to the caster connector, a primary drive gear, a primary driven gear, and a secondary driven gear.

Abstract: A tool device, such as a lawnmower, or a steerable-wheel assembly therefor may include a frame, a walking element, a drive motor, a steerable-wheel assembly (SWA), and one or more controllers attached to the frame. The walking element may be coupled to the frame. The drive motor may selectively power the walking element. The SWA may be attached to the frame apart from the walking element. The SWA may include a caster connector pivotably mounted to the frame to rotate about a pivot axis, a steerable wheel rotatably coupled to the caster connector, a first sensor configured to detect a pivotable position of the caster connector, and a second sensor configured to detect the set reference point.
