A robotic vehicle includes a chassis, a cabin, a driving device, a plurality of detection devices, and a control device. The cabin is installed in the upper portion of the chassis. The driving device is positioned on the chassis for moving the robotic vehicle and rotating the cabin. A plurality of detection devices and a control device are installed for reconnoitering an area. The two sides of the chassis are coupled to track wheels, and a front portion of the chassis is coupled to a climbing support mechanism.

A vehicle may include a chassis, at least one wheel rotatably coupled to the chassis, and a magnet positioning inside of the at least one wheel. The magnet may be rotatably coupled to the wheel with a first shaft, such that the magnet is rotatable about a first axis. In some instances, the magnet may also be coupled to the first shaft with a second shaft, such that the magnet is rotatable relative to the wheel about a second axis. Accordingly, the magnet may have either one or two degrees of freedom of movement within the at least one wheel. The magnet may rotate passively, actively, or semi-actively in one or more directions to provide an attractive force toward a ferromagnetic surface to secure the vehicle to the ferromagnetic surface.
