Résumé : Can robots of a swarm cooperate to solve together a complex cognitive problem that none of them can solve alone? TS-Swarm is a robot swarm that autonomously sequences tasks at run time and can therefore operate even if the correct order of execution is unknown at design time. The ability to sequence tasks endows robot swarms with unprecedented autonomy and is an important step towards the uptake of swarm robotics in a range of practical applications.
