### Abstract

This paper addresses the problem of efficiently achieving visual predictive control tasks. To this end, a memory of motion, containing a set of trajectories built off-line, is used for leveraging precomputation and dealing with difficult visual tasks. Regression techniques, such as k-nearest neighbors and Gaussian process regression, are used to query the memory and provide on-line the control optimization process with a warm-start and way points. The proposed technique allows the robot to achieve difficult tasks and, at the same time, keep the execution time limited. Simulation and experimental results, carried out with a 7-axis manipulator, show the effectiveness of the approach.
