The invention is directed to a stair-climbing remote control utility wagon. The wagon provides a forward chassis arm and a rear chassis arm which are interleaved with each other, providing a broad, stable base. The forward chassis arm terminates in a forward chassis, and the rear chassis arm terminates in a rear chassis. The forward chassis and the rear chassis provide powerful, battery-powered electric motors and caterpillar tracks. The forward chassis arm and rear chassis arm are fully articulated by servomotors, providing telescoping segments which may be extended and retracted with servomotors, and the motor housing of the forward chassis arm further provides infrared sensors, which are controlled by a microprocessor to enable the wagon to climb a flight of stairs. The forward chassis arm and rear chassis arm may also be used to elevate the bed of the wagon to any height, up to 48 inches.
