A system for accurately detecting lateral collisions with an obstacle is introduced. When a mobile robot rotates, it might collide with a wall or pillar it had not seen before. With this system, the collision can be detected, and a recovery manoeuvre performed, minimizing physical damage to the robot and downtime, without user intervention. Otherwise, the robot would get stuck trying to move to the next target, requiring manual intervention. Finally, when a collision is detected, the obstacle position and orientation can be estimated, and this information can be saved for future use (such as mapping).
