Claim 10:
11. A method performed by a mobile robot to avoid collisions while crossing a road at a pedestrian crossing, the method comprising:
sensing road conditions with at least one first sensor;
sensing road conditions with at least one second sensor; and
with a processor connected to the at least one first sensor and to the at least one second sensor:
determining, based on the second sensor, a change in the road conditions indicating that a hazardous approaching object is on a trajectory that intersects a trajectory of the mobile robot within a certain minimum limit, wherein the trajectory of the mobile robot comprises crossing the road from a pedestrian pathway; and
causing the mobile robot to initiate a collision avoidance maneuver in response to determining said change in road conditions, to thereby avoid a collision with the hazardous approaching object;, wherein the method further comprises in response to said change in road conditions:
checking if an object is behind the mobile robot and/or checking if an object is in front of the mobile robot;
moving backward, if no object is detected behind the mobile robot; and
moving forward, if an object is detected behind the mobile robot and no object is detected ahead of the mobile robot.
