A dynamically balanced, tracked robot, which can switch between dynamically balanced (wheeled) operation and tracked operation, can include a body and at least one wheel rotatably mounted to the body. At least one strut can also be mounted to the body so that it extends therefrom, and an idler wheel can be fixed to the distal end of the strut. A track can be slipped over the wheel and that idler wheel, so that the track frictionally engages both the wheel and the idler wheel. The robot can have a defined vertical reference vector and a processor. The processor can have non-transitory written instructions that, when accomplished, cause the vertical reference vector to be parallel with a vector defined by the robot axis and the revised post-installation center of gravity, to continue to allow for dynamic balancing of the newly-tracked robot.

A vehicle with a track system including a track for traction of the vehicle on a ground can be monitored (e.g., during operation of the vehicle) to obtain information regarding the vehicle, including information regarding the track system, such as a temperature and/or another characteristic of a wheel of the track system sensed by a sensor of that wheel and/or a temperature and/or another characteristic of the track sensed by a sensor of the track, which can be used to inform a user (e.g., an operator of the vehicle), assessing wear, vibration, and/or other aspects of the track system, evaluating use (e.g., a duty cycle), performance, and/or other aspects of the vehicle, and/or control the vehicle (e.g., a speed of the vehicle), for properly aligning the track and/or other purposes. This may be useful, for example, to help prevent rapid wear or other deterioration of the track and/or for various other reasons.

A ground-engaging track system includes a track having a first track chain and a second track chain, and an idler having pockets formed in an outer idler rim to receive inboard rail protrusions on track links in the first track chain and the second track chain. The inboard rail protrusions project from an inboard link side, and a central pad of an upper rail surface in the track link includes an anti-scalloping bump-out formed on the inboard rail protrusion.

A rotating assembly for a machine is disclosed herein. The rotating assembly includes an annular support structure and a shaft assembly. The annular support structure includes a bore therethrough and protrusion extending helically around a portion of the bore. The shaft assembly includes a shaft and a collar coupled to the shaft. The collar includes a plurality of grooves located at the outer surface of the collar. The collar is positioned within the bore of the annular support structure such that the plurality of grooves are adjacent to the protrusion. As the annular support structure rotates, the protrusion rotates and is configured to move debris and mud out of the rotating assembly.

A roller assembly is disclosed. The roller assembly may have a roller shell. The roller shell may have a bore. The roller assembly may also have a substantially cylindrical shaft. The shaft may extend from a shaft proximate end to a shaft distal end. The shaft may be disposed within the bore. The roller assembly may also have a first collar disposed between the shaft proximate end and the roller shell. The first collar may be interferingly engaged with the shaft. The roller assembly may further have a second collar disposed between the shaft distal end and the roller shell. The second collar may also be interferingly engaged with the shaft.

Provided is a track drive for outdoor power equipment including a support frame and a drive axle configured to attach to an associated drive hub. A hub bearing is mounted on the drive axle and the support frame enabling the drive axle to rotate relative to the support frame. A drive sprocket is attached to the drive axle and includes an interior half sprocket and an exterior half sprocket. The half sprockets are located on either side of the support frame. Drive teeth are spaced radially about the drive sprocket. The drive sprocket is movably engaged with an endless track to transmit force to rotate the endless track and propel the outdoor power equipment. A kit for adding or replacing a track drive of outdoor power equipment is also provided.
