A mobile medical device is driven by a chassis. The movement is brought about, or at least supported by, at least one drive. A direction influencing device varies the direction of movement. Both the drive and the direction influencing device may be activated by a control device. End stations and paths leading to the end stations, as well as a current position of the device, are known to the control device. The control device accepts a drive request from an operator and establishes an at least approximate desired direction of the movement. The control device activates the drive while accepting the drive request and activates the direction influencing device to drive the device on one of the paths while accepting the drive request and while the current position of the device is approximately on the path. Furthermore, the control device continuously updates the position of the device during movement.

A system and a method for facilitating the autonomous navigation of a utility and delivery cart implements new means for a motorized cart to operate in different environments under specific operational conditions. The system includes a structural frame, a controller, a plurality of navigational sensors, a portable power source, a pair of caster wheels, and a pair of motorized wheels. The structural frame corresponds to the main structure of the system that can be customized to carry different payloads and accommodate different accessories. The pair of caster wheels and the pair of motorized wheels enable the movement of the structural frame. The controller and the plurality of navigational sensors allow the autonomous operation of the pair of motorized wheels under specific operational configurations.

A truck includes a body, left and right wheels provided on the body, left and right drive units driving the wheels, a handle provided on the body, a sensor, and a control device. The sensor detects a front-rear load and a moment about a vertical axis applied to the handle. The control device sets a target front-rear velocity of the body based on the front-rear load, and sets a target angular velocity of the body about a vertical axis based on the moment about the vertical axis. In a case where a product of the target front-rear velocity and the target angular velocity is greater than a predetermined threshold, the control device performs correction processing on the target front-rear velocity so that the product is equal to or less than the threshold, and controls the drive units based on the corrected target front-rear velocity and the target angular velocity.
