<P>PROBLEM TO BE SOLVED: To provide an autonomous coverage robot that has a rectangular forward portion and an arcuate rearward portion, and can maneuver so as to bring the rectangular section flush with a wall corner or wall edge, with the cleaning mechanism extending into the wall corner or wall edge. <P>SOLUTION: The autonomous coverage robot includes: a chassis having a rectangular forward portion and an arcuate rearward portion; a power source carried by the chassis; a cleaning assembly having a roller brush; a bin for receiving debris agitated by the cleaning assembly; an idler wheel disposed within a profile circle, along a transverse axis parallel to the drive axis; and a drive system arranged in the rearward portion of the chassis, and having right and left drive wheels. The autonomous coverage robot is configured such that the roller brush is retained above a cleaning surface forward of the idler wheel; the center of gravity of the robot is between a drive axis and the idler wheel, the center of gravity of the robot including a variable mass of debris within the bin and a mass of the roller brush motor, etc.; the right and left drive wheels are parallel to a horizontal axis, and define a drive axis along or rearward of a parallel diameter of the profile circle. <P>COPYRIGHT: (C)2012,JPO&INPIT |
