1. An autonomous coverage robot comprising:

  • a drive system configured to maneuver the robot according to a heading setting and a speed setting;

    a bump sensor responsive to a collision of the robot with an obstacle in a forward direction; and

    a proximity sensor responsive to a potential obstacle forward of the robot;

    wherein the drive system is configured to reduce the speed setting in response to a signal from the proximity sensor indicating detection of a potential obstacle, while continuing to advance the robot according to the heading setting;

    wherein the drive system is configured to increase the speed setting if the drive system does not receive a subsequent signal indicating the presence of an obstacle while continuing to advance according to the heading setting and the reduced speed setting; and

    wherein the drive system is configured to alter the heading setting in response to a signal received from the bump sensor indicating contact with an obstacle.
