The controller being operable to calculate a vehicle loading factor before the vehicle moves and to prevent operation of the prime mover if the vehicle loading factor that exceeds a selected load threshold.

Methods perform one or more dispatched medical logistics operations using a modular autonomous bot apparatus assembly and a dispatch server where the operations are related to a diagnosis kit for treating a patient. The MAM of the bot receives a dispatch command, verifies compatibility of the bot assembly with the dispatched operation(s), receives a diagnosis kit in the CSS, has the MAM autonomously causing the MB to move to a destination location while notifying the authorized delivery recipient for the diagnosis kit of the approaching delivery. With appropriate authentication input received, the MAM coordinates with the CSS to provide access to the kit, monitor unloading of the kit, provide instructional information on use of the kit, and autonomously cause the MB to return to the original location with a return item related to the diagnosis kit with notification to personnel at the medical entity about the return item.

Disclosed is a pulling compensation apparatus for a vehicle including: a main body part capable of loading a power engine of the vehicle and goods or carrying people; a transfer part transferring the main body part; a sensor part sensing a height and a slope of the main body part, pulling due to motion inertia and an obstacle to transmit a signal; a controller embedded with a computer receiving the signal of the sensor part; and a pulling reduction part controlled by the controller to reduce the pulling and shocks of the main body part. The pulling reduction part varies the height to reduce the pulling and shocks of the main body part when the pulling of the main body part and the obstacle are sensed by the sensor part.

Systems and methods are disclosed herein for automatically controlling wheel lean in a work vehicle (e.g., a motor grader) comprising a front portion with an axle and a plurality of traction wheels configured to lean at a wheel-lean angle relative thereto. Based on output signals from one or more sensors mounted on the work vehicle, work conditions are detected comprising an actual wheel-lean angle of at least one wheel relative to the axle, an oscillation angle of the axle, and a slope of the terrain. In automatic control operations, wheel lean is automatically directed to a predetermined orientation (e.g., corresponding to a direction of gravity), based at least on detected work conditions. Wheel lean may further be automatically directed based on detected steering inputs for positioning of the traction wheels and a detected articulation angle for positioning of the front portion of the work vehicle relative to the rear portion.

A crane for lifting and transporting loads includes a base frame for transferring the loads of the crane onto a support surface by a plurality of wheels. The wheels are capable of rotating relative to the base frame so as to change the camber angle of the wheels.
