Development and demonstration of an autonomous collision avoidance algorithm aboard the ISS

Since 2006 the SPHERES facility aboard the International Space Station has enabled research of high-risk autonomy algorithms which would not otherwise be conducted in a regular space mission. A thread of research with several demonstrations aboard the ISS is Collision Avoidance. Through two SPHERES test sessions over the course of a year, researchers have developed an efficient autonomous collision avoidance controller, deployed it on a representative microprocessor, and demonstrated its effectiveness as a reliable low-level safetey routine.
