The invention relates to a device for managing the movements of a robot configured to treat a surface, said device including: acquisition means for acquiring a three-dimensional representation (Re) of said surface to be treated; and determination means for determining a sequence of movements on the basis of said three-dimensional representation (Re) of said surface to be treated; said determination means comprising at least one three-dimensional generic model (m1-m3) for which a plurality of sequences of movements (Tx) are known; said device including adjustment means for adjusting said generic model (m1-m3) with said three-dimensional representation (Re) of said surface to be treated that are able to deform said generic model (m1-m3) and known sequences of movements (Tx) so as to correspond to said three-dimensional representation (Re) of said surface to be treated.
