AB - Quality-Diversity optimization is a new family of optimization al-gorithms that, instead of searching for a single optimal solutionto solving a task, searches for a large collection of solutions thatall solve the task in a different way. This approach is particularly promising for learning behavioral repertoires in robotics, as sucha diversity of behaviors enables robots to be more versatile and resilient. However, these algorithms require the user to manually defi€ne behavioral descriptors, which is used to determine whethertwo solutions are different or similar. The choice of a behavioral de-scriptor is crucial, as it completely changes the solution types thatthe algorithm derives. In this paper, we introduce a new method to automatically de€fine this descriptor by combining Quality-Diversityalgorithms with unsupervised dimensionality reduction algorithms. This approach enables robots to autonomously discover the rangeof their capabilities while interacting with their environment. The results from two experimental scenarios demonstrate that robot canautonomously discover a large range of possible behaviors, without any prior knowledge about their morphology and environment. Furthermore, these behaviors are deemed to be similar to hand-crafted solutions that uses domain knowledge and signi€cantly more diverse than when using existing unsupervised methods.
