Biological evidence shows that animals are capable of evading eminentcollision without using depth information, relying solely on looming stimuli.In robotics, collision avoidance among uncooperative vehicles requiresmeasurement of relative distance to the obstacle. Small, low-cost mobile robotsand UAVs might be unable to carry distance measuring sensors, like LIDARS anddepth cameras. We propose a control framework suitable for a unicycle-likevehicle moving in a 2D plane that achieves collision avoidance. The controlstrategy is inspired by the reaction of invertebrates to approaching obstacles,relying exclusively on line-of-sight (LOS) angle, LOS angle rate, andtime-to-collision as feedback. Those quantities can readily be estimated from amonocular camera vision system onboard a mobile robot. The proposed avoidancelaw commands the heading angle to circumvent a moving obstacle with unknownposition, while the velocity controller is left as a degree of freedom toaccomplish other mission objectives. Theoretical guarantees are provided toshow that minimum separation between the vehicle and the obstacle is attainedregardless of the exogenous tracking controller.
