Patent attributes
This disclosure describes, in part, wheel apparatuses that includes weight sensors. For instance, a wheel apparatus may include at least a hub, a rim located around the hub, a tire located around the rim, weight sensor(s) located within the rim, and a caster that connects the wheel apparatus to a mobile apparatus. In some examples, the wheel apparatus may include additional components, such as one or more batteries, a generator, and/or a wireless communication interface. As such, the mobile apparatus may use the wheel sensors included in the wheel apparatuses to determine weights, such as weights of items added to the mobile apparatus. In some examples, the wheel apparatuses are configured such that the weight sensors remain perpendicular with respect to a ground plane so that the mobile apparatus may use the weight sensors to determine the weights even when the mobile apparatus is moving.
