  A classic task in robotics is tracking a target in the external environment.
There are several well-documented approaches to this problem. This paper
presents a novel approach to this problem using infrared time of flight
sensors. The use of infrared time of flight sensors is not common as a tracking
approach, typically used for simple motion detectors. However, with the
approach highlighted in this paper they can be used to accurately track the
position of a moving subject. Traditional approaches to the tracking problem
often include cameras, or ultrasonic sensors. These approaches can be expensive
and overcompensating in some use cases. The method focused on in this paper can
be superior in terms of cost and simplicity.
