The precise and continuous tracking of millimetric-sized walkers—such as ants—is quite important in behavioral studies. However, due to technical limitations, most studies concentrate on trajectories within areas no more than 100 times bigger than the size of the walker or longer trajectories at the expense of either accuracy or continuity. Our work describes a scientific instrument designed to push the boundaries of precise and continuous motion analysis up to 1000 body lengths or more. It consists of a mobile robotic platform that uses digital image processing techniques to track the targets in real time by calculating their spatial position. During the experiments, all the images are stored and afterwards processed to estimate with higher precision the path traced by the walkers. Some preliminary results achieved using the proposed tracking system are presented. [ABSTRACT FROM AUTHOR]

This article discusses the challenges associated with motion tracking of insects. The authors comment on the various methods of insect tracking, including studies of bees, ants, and spiders. They examine the development of tracking algorithms to detect insect movement, including methods such as optical flow, color matching, and template matching.
