Abstract: A method to compute a pixel map of probabilities of absence and presence of an obstacle in the environment of an autonomous robot comprising at least one sensor grouped in at least one set of sensors that detect obstacles of similar types and have its own sensor initial map of probability of absence of obstacles is provided. The method comprises the steps of initializing a map around the robot and attached to the robot with a predefined value of probability of absence or presence of an obstacle, acquiring data representative of the absence or presence of an obstacle around the robot from at least one sensing procedure, and concurrently updating values of probabilities using data from sensing procedure and modifying the probabilities of absence or presence of obstacle from previous observations to a value closer to a predefined value.

Abstract: A humanoid robot which can move on its lower limb to execute a trajectory and is capable of detecting intrusion of obstacles in a safety zone defined around its body as a function of its speed is provided. Preferably when the robot executes a predefined trajectory, for instance a part of a choreography, the robot which avoids collision with an obstacle will rejoin its original trajectory after avoidance of the obstacle. Rejoining trajectory and speed of the robot are adapted so that it is resynchronized with the initial trajectory. Advantageously, the speed of the joints of the upper members of the robot is adapted in case the distance with an obstacle decreases below a preset minimum. Also, the joints are stopped in case a collision of the upper members with the obstacle is predicted.
