Driven lift axles and associated systems and components are provided for use on heavy duty trucks, trailers, and/or other vehicles. Driven lift axle systems may include one or more motors mounted to the lift axle to provide torque to drive one or more wheels of the lift axle. Various mounting configurations of such motors are possible, such as arranging a motor on the axle to provide torque at a conventional driveshaft input by interfacing with a differential drive gear, positioning a motor at each of the wheel ends of the axle to provide torque directly to the wheels, etc. Each wheel can be driven by a separate motor, allowing for independent control of the torque applied to each wheel. Lift axles described herein can be suitable for use with various motors capable of applying torque to the axle and/or wheels, such as electric motors, hydraulic motors, internal combustion engines, etc.

A wheel assembly for an agricultural implement. The agricultural equipment includes a laterally-extending toolbar with one or more agricultural tools extending from the toolbar. The wheel assembly comprises a wheel configured to rotate along a ground surface. The wheel assembly additionally comprises a base bracket configured to be rigidly secured to the toolbar. The wheel assembly further comprises a wheel bracket adjustably engaged with the base bracket. Adjustment of the wheel bracket with respect to the base bracket causes a corresponding lateral shifting of the wheel with respect to the toolbar.

A suspension system for liftable steerable axles has at least one steering knuckle; at least one pistonless bellows air spring actuator (ie., damper air spring); and a steering axle structure that has, at each end, a kingpin housing boss, a kingpin fixed into the kingpin boss, and a pair of steering knuckles that rotate around the kingpin and are supported by the kingpin housing; wherein the steering knuckles are connected at the bottom of each other side to side by a tie rod assembly that respond to each others rotational inputs; and further having the damper air spring being connected to the steering knuckle so that, given a supplied pneumatic air force, the damper air spring stabilizes and dampens the steering road inputs when in motion.

A delivery robot is provided for the delivery of home dialysis supplies to a home dwelling of a home dialysis patient. The delivery robot can be an autonomous delivery robot. The delivery robot can have an outdoor set of wheels or other traction devices, and an indoor set of wheels or other traction devices. The delivery robot can be configured to switch between an outdoor configuration for traversing an outdoor surface, and an indoor configuration for traversing an inside surface, inside the home of the home dialysis patient. A network is also provided and can include a robot delivery vehicle, a warehouse, a remote computer within the patient's home, or a combination thereof. Methods of delivering home dialysis supplies are also provided that utilize the delivery robot and network.

A robotic vehicle for traversing surfaces comprises a chassis having a plurality of wheels mounted thereto. Two magnetic drive wheels are spaced apart in a lateral direction and rotate about a rotational axis while a stabilizing wheel is provided in front of or behind the two drive wheels. The drive wheels are configured to be driven independently, thereby driving and steering the vehicle along the surface. The vehicle also includes a sensor probe assembly that is supported by the chassis and configured to take measurements of the surface being traversed. In accordance with a salient aspect, the vehicle includes a probe normalization mechanism that is configured to determine the surface curvature and adjust the orientation of the probe transducer as a function of the curvature of the surface, thereby maintaining the probe at the preferred inspection angle irrespective of changes in the surface curvature with vehicle movement.

A vehicle can have: (1) a first pair of rear wheels with a first pair of tires configured to be able to bear a weight of the vehicle and (2) a second pair of rear wheels with a second pair of tires installed on the second pair of rear wheels and configured to be selectively inflatable. The first pair of wheels can be disposed on a first pair of axles. The second pair of wheels can be disposed on the first pair of axles or on a second axle. In an inflated state, the second pair of tires can be configured to be able to bear the weight of the vehicle. In a deflated state, the second pair of tires can lack being configured to bear the weight of the vehicle. An individual or a controller can cause the vehicle to have a conventional configuration or a dually configuration.

An unmanned aerial vehicle (UAV) includes a body constructed to enable the UAV to fly and three or more legs connected to the body and configured to land and perch the UAV on a curved ferromagnetic surface. Each leg includes a first portion connected to the body, a second portion including a magnet and configured to magnetically attach and maintain the magnetic attachment of the leg to the ferromagnetic surface during the landing and perching, and a passive articulation joint connecting the first and second portions and configured to passively articulate the second portion with respect to the first portion in response to the second portion approaching the ferromagnetic surface. The UAV further includes a releasable crawler including magnetic wheels which detach the crawler from the body during the perching and maneuver the crawler on the ferromagnetic surface while magnetically attaching the crawler to the ferromagnetic surface after detachment.
