An autonomous coverage robot includes a drive system, a bump sensor, and a proximity sensor. The drive system is configured to maneuver the robot according to a heading (turn) setting and a speed setting. The bump sensor is responsive to a collision of the robot with an obstacle in a forward direction. A method of navigating an autonomous coverage robot with respect to an object on a floor includes the robot autonomously traversing the floor in a cleaning mode at a full cleaning speed. Upon sensing a proximity of the object forward of the robot, the robot reduces the cleaning speed to a reduced cleaning speed while continuing towards the object until the robot detects a contact with the object. Upon sensing contact with the object, the robot turns with respect to the object and cleans next to the object, optionally substantially at the reduced cleaning speed.

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; anda 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; andwherein 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. 2. The robot of claim 1 wherein the drive system is configured to alter the heading setting in response to the signals received from the bump sensor and the proximity sensor to follow a perimeter of the obstacle. 3. The robot of claim 1 wherein the drive system is configured to alter the heading setting in response to the signals received from the bump sensor and the proximity sensor to direct the robot away from the obstacle. 4. The robot of claim 1 wherein the proximity sensor comprises at least one infrared emitter and receive pair. 5. The robot of claim 1 wherein the proximity sensor comprises a sonar device. 6. The robot of claim 1 wherein the bump sensor comprises a switch. 7. The robot of claim 1 wherein the bump sensor comprises a capacitive sensor. 8. The robot of claim 1 wherein the drive system is configured to maneuver the robot at a torque setting, wherein the drive system is configured to alter the torque setting in response to a signal received from the bump sensor indicating contact with an obstacle. 9. The robot of claim 8 wherein the drive system increases the torque setting in response to a signal received from the bump sensor indicating contact with an obstacle. 10. The robot of claim 1 wherein the drive system is configured to increase the speed setting if the drive system does not receive the subsequent signal from the bump sensor indicating the presence of an obstacle within an elapsed time after the speed setting is reduced. 11. A method of navigating an autonomous coverage robot with respect to an object on a floor, the method comprising the robot: autonomously traversing the floor in a cleaning mode at a cleaning speed;upon sensing a proximity of the object forward of the robot, reducing the cleaning speed to a reduced speed while continuing towards the object;in response to not sensing the presence of the object while advancing at the reduced speed, increasing the speed setting; andin response to sensing contact with the object, turning with respect to the object and cleaning next to the object. 12. The method of claim 11 wherein the robot follows a perimeter of the object while cleaning next to the object. 13. The method of claim 11 wherein the robot maintains a substantially constant following distance from the object while cleaning next to the object in response to the contact with the object. 14. The method of claim 13 wherein the following distance from the object is substantially a distance between the robot and the object substantially immediately after the contact with the object. 15. The method of claim 13 wherein the following distance from the object is between about 0 and 2 inches. 16. The method of claim 13 wherein the robot performs a maneuver to move around the object in response to the contact with the object. 17. The method of claim 16 wherein the maneuver comprises the robot moving in a substantially semi-circular path around the object. 18. The method of claim 16 wherein the maneuver comprises the robot moving away from the object and then moving in a direction substantially tangential to the object. 19. The method of claim 13 wherein the robot decreases the cleaning speed to a reduced speed at a constant rate. 20.
