A robot R includes a pair of crawler devices 2 supported by a body 1. Each of the crawler devices 2 includes a crawler unit 3 supported by the body 1 such that the crawler unit 3 is rotatable about a first rotational axis L. The crawler unit 3 includes a support 10 extending along the first rotational axis L1 and a pair of crawler parts 20A, 20B mounted on the support 10. Each of the crawler device 2 includes a rolling driving member 46 connected to the support 10 of the crawler unit 3, a rolling motor 60 that rotationally drives the rolling driving member 46, a crawler drive shaft 41 extending along the first rotational axis L1 through a gap between the pair of crawler parts 20A, 20B, a crawler motor 50 that rotationally drives the crawler drive shaft 41 and a torque transmitting mechanism 42 that transmits rotary torque of the crawler drive shaft 41 to the pair of crawler parts 20A, 20B, The crawler motor 50, as well as the rolling motor 60, is disposed outside of the crawler unit 3.

One general aspect includes a tethered temperature sensor for use within a vehicle track. The tethered temperature sensor includes one or more sensors for measuring temperature located in a high strain and high temperature region of the vehicle track. The sensor also includes circuitry configured to control and/or monitor the one or more sensors and located in a low strain and low temperature region of the vehicle track. The sensor also includes a housing to contain the circuitry. The sensor also includes an encapsulating material that fills an interior of the housing.

A work machine may include an drive frame, a drivable track coupled to the drive frame, an idler wheel coupled to the drive frame to facilitate movement of the drivable track, and a wheel weight coupleable to the idler wheel. The wheel weight may be coupled to the idler wheel without removing the idler wheel from the drive frame.
