A plurality of toy vehicles can race together in a track set. The track system comprises of different types of plastic tubes, toy vehicles and transmitter. The toy tube can be in different shapes such as straight type, curved type, X-type, Y-type and open-type. The tubes can be assembled by end users with simply snapping two symmetrical half tubes together. The vehicle has a drive wheel resiliently urged towards an inner surface of the tube for moving frictionally along the inner surface.

A vehicle configured to move through a network of interconnected tubes includes a body, a motor, a motorized wheel, a biasing assembly, and a first element. The motorized wheel directly engages an inner surface of the tubes. The biasing assembly causes the motorized wheel to maintain continuous contact with the inner surface of the tubes during operation. A waist of the vehicle is constrained by an inner diameter (D) of the curved tube, a radius of curvature (R) of the curved tube, and a length (L) of the wheelbase of the vehicle. The waist of the body is sized such that the vehicle can freely move within any of the tubes without getting stuck therein.

A first battling device has one or more processors, memory, one or more wireless receiving components; and one or more driving component for moving the first battling device. The first battling device receives a radio signal by using at least one of the wireless receiving components, the radio signal being broadcast by a wireless transmitting component of a second battling device that is distinct from the first battling device. The first battling device determines a position of the first battling device relative to the second battling device according to respective position information of the at least one of the wireless receiving components of the first battling device that have received the radio signal. The first battling device performs a predetermined action according to the respective position information of the at least one of the wireless receiving components of the first battling device that have received the radio signal.

A housing includes a head, a head mount, and a bracket. The head includes a midsection, a rod extending from the midsection, and a connection member extending in an opposite direction therefrom. A bore extends through the length of the midsection, the rod, and the connection member. The head mount comprises a hollow receiving member open at a first end and has a bottom face at a second end. The bracket includes first and second bracket sections. A top face of the first section is fixed to the bottom face of the hollow receiving member. In a use position, an inside face of the first bracket section is positioned against a first side of a surface, and an inside face of the second bracket section is positioned against a second opposing side of the surface. The first and second bracket sections are secured together using mechanical fasteners.
