Bats use four key tactics for accurate target tracking

The ability of "target tracking," i.e., keeping a target object in sight, is essential for various activities and has improved in animals and machines through the evolution of life and technology, respectively. Because most sensing systems are inevitably subject to a certain degree of delay caused by information processing, many studies have addressed the challenge of overcoming this delay constraint for more accurate target tracking. At this point, studying animals' sophisticated tracking behavior would bring a significant breakthrough against this fundamental problem.
