Compact autonomous coverage robot
First Claim
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.

Abstract
An autonomous coverage robot includes a chassis having forward and rearward portions and a drive system carried by the chassis. The forward portion of the chassis defines a substantially rectangular shape. The robot includes a cleaning assembly mounted on the forward portion of the chassis and a bin disposed adjacent the cleaning assembly and configured to receive debris agitated by the cleaning assembly. A bin cover is pivotally attached to a lower portion of the chassis and configured to rotate between a first, closed position providing closure of an opening defined by the bin and a second, open position providing access to the bin opening. The robot includes a body attached to the chassis and a handle disposed on an upper portion of the body. A bin cover release is actuatable from substantially near the handle.
