Abstract:
A portable, lightweight racer vehicle includes a body, a battery-powered motor, a motorized wheel, a first wheel, and a spring-loaded wheel. The first wheel is larger than the motorized wheel and the spring-loaded wheel. A tube section includes a first half section having a pair of interlocking fingers and a pair of notches; and a second half section having a pair of interlocking fingers and a pair of notches. The two halves are removably snap-fit or press-fit together by joining the pair of interlocking fingers of the first half section with the pair of notches of the second half section while simultaneously joining the pair of interlocking fingers of the second half section with the pair of notches of the first half section. A splitter pipe includes a body having an input port and at least two output ports, and a remotely controlled valve between the input port and the at least two output ports.
Abstract:
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.
