Vehicles are disclosed which have a lower center of gravity than existing all-terrain, amphibious, and unmanned ground vehicles due to the location of propulsion units and other vehicle components inside the wheels of the vehicle. The vehicles can climb over large obstacles yet are also able to corner at high speeds. The vehicles can be configured for direct manual operation or operation by remote control, and can also be configured for a wide variety of missions.

A towable road motor vehicle including: at least three wheels, capable of driving the motor vehicle on a level road, distributed between two front and rear wheel trains of the motor vehicle; a chassis, including an articulation device, interposed between front and rear portions of the chassis and enabling the front portion to pivot, relative to the rear portion, to modify an articulation angle of the vehicle; front and rear hitches, respectively positioned at the front and rear of the motor vehicle, and a steering device, capable of modifying the steering angle of each wheel of the front train in response to a command by a driver of the vehicle, the steering device adapted to be actuated independently of the articulation device.

Disclosed is a draw-bar box-type quickly folding micro electric vehicle, comprising of a seat frame assembly (1) that is horizontally arranged, the top surface of which is provided with a foldable backrest. A pair of symmetrically arranged rear wheel assemblies (2) are arranged at a position, close to a rear of the vehicle, on the bottom surface of the seat frame assembly (1), and two vertically downward first connecting posts (101), which are provided near the front of the lower end of the seat frame assembly (1). A footrest assembly (4) is hinged to the lower ends of the two first connecting posts (101) through the first connecting assemblies (3). The footrest assembly (4) is arranged parallel to the seat frame assembly (1), and the plane of the footrest assembly (4) is lower than the plane of the seat frame assembly (1). A steering column assembly (5) is hinged at the end of the footrest assembly (4) away from the seat frame assembly (1), and a front wheel assembly (6), with a power device, is attached at the lower end of the steering column assembly (5). A very low footrest assembly (4) is hinged to the seta frame assembly (1) by means of the first connecting assembly (3), so that the user does not need to raise their legs to use the vehicle. Thus, use of the vehicle is convenient and safety risks are reduced.

Systems and methods for dynamically magnetizing a chassis of a robotic vehicle are provided. The system can include a chassis having a fixed first section with a first magnet, and a moveable a second section having a second magnet with an opposition orientation relative to the first magnet. The second section is located above or below the first section and includes a mechanism that moves the second section relative to the first magnet. The system also includes an actuator connected to the second section, and a control system operatively connected to the actuator. In the systems and methods, the control system can send commands to the actuator to selectively move the mechanism, thereby moving the second section relative to the location of the first magnet to activate or inactivate a magnetic force on a portion of the chassis.
