1. A toy motion tracking kit, the kit comprising:
- a movable toy, the toy being adapted to emit a signal pulse; and
a movable tracking system separate from the movable toy, said movable tracking system comprising;
at least one pair of signal receivers, wherein each of the at least one pair of signal receivers comprises a first directional receiver and a second directional receiver, and wherein each of the at least one pair of signal receivers defines a first direction pointing from the second directional receiver to the first directional receiver and a second direction pointing from the first directional receiver to the second directional receiver; and
a microprocessor programmed to direct the motion of the movable tracking system;
wherein, for each of the at least one pair of signal receivers, the signal pulse is adapted to activate the first directional receiver for a first length of time and to activate the second directional receiver for a second length of time, and the microprocessor is adapted to record the first length of time and the second length of time; and
wherein, for each of the at least one pair of signal receivers;
when the first length of time is greater than the second length of time by an amount greater than a predetermined amount, the microprocessor is programmed to direct the movable tracking system to move in the first direction;
when the first length of time is less than the second length of time by an amount greater than the predetermined amount, the microprocessor is programmed to direct the movable tracking system to move in the second direction; and
when the first length of time is about equal to the second length of time, the microprocessor is programmed to direct the movable tracking system to be motionless in the first direction and in the second direction.

Abstract
A system is provided comprising an automatic toy tracking system adapted to track an infrared signal emitted by a remotely controlled toy vehicle. The tracking system has a series of infrared receivers and is adapted to pivot and rotate in response to the relative intensity of the infrared signal received by each receiver. When the tracking system has positively ascertained the location of the infrared emitter, the tracking system can be adapted to fire at least one projectile at the toy vehicle.
