1. An autonomous coverage robot comprising:

  • a chassis having forward and rearward portions, when viewed from above an outer peripheral shape of the forward portion defining a substantially rectangular shape and an outer peripheral shape of the rear-ward portion defining an arcuate shape;

    a drive system carried by the chassis configured to maneuver the robot over a cleaning surface;

    right and left differentially driven drive wheels;

    a cleaning assembly mounted on the forward portion of the chassis; and

    bump sensors disposed at the forward corners of the chassis, with at least one bump sensor disposed on each side of each corner such that bump sensors on a lateral side of the robot detect bumps independently of bump sensors on a front side of the robot, thus allowing the robot to determine a direction and/or location of a collision.
