A coverage robot comprising: a chassis;multiple drive wheel assemblies disposed on the chassis, each drive wheel assembly comprising: a drive wheel assembly housing;a wheel rotatably coupled to the housing; anda wheel drive motor carried by the drive wheel assembly housing and operable to drive t
1. A coverage robot comprising: a chassis;multiple drive wheel assemblies disposed on the chassis, each drive wheel assembly comprising: a drive wheel assembly housing;a wheel rotatably coupled to the housing; anda wheel drive motor carried by the drive wheel assembly housing and operable to drive the wheel; anda cleaning assembly carried by the chassis, the cleaning assembly comprising: a cleaning assembly housing;a cleaning head rotatably coupled to the cleaning assembly housing; anda cleaning drive motor carried by cleaning assembly housing and operable to drive the cleaning head;wherein the wheel assemblies and the cleaning assembly are each separately and independently removable from respective receptacles of the chassis as complete units. 2. The robot of claim 1 further comprising a removable cover secured to a bottom of the chassis, the cover securing each wheel assembly and cleaning assembly within their respective receptacles. 3. The robot of claim 1 wherein each wheel assembly further comprises a power connector disposed on an outer surface of the drive wheel assembly housing and configured to mate with a corresponding chassis power connector within its respective receptacle as the drive wheel assembly is placed within the receptacle, to establish an electric power connection to the wheel assembly. 4. The robot of claim 1 wherein the cleaning assembly further comprises a power connector disposed on an outer surface of the cleaning assembly housing and configured to mate with a corresponding chassis power connector within its respective receptacle as the cleaning assembly is placed within the receptacle, to establish an electric power connection to the cleaning assembly. 5. The robot of claim 1 further comprising an electric battery carried by the chassis. 6. The robot of claim 1 further comprising a removable caster wheel assembly disposed on the chassis. 7. The robot of claim 1 wherein each drive wheel assembly further comprises a linkage suspending the wheel from a forward portion of the chassis. 8. The robot of claim 1 wherein each drive wheel assembly further comprises at least one proximity sensor to detect an absence of an adjacent floor. 9. The robot of claim 1 further comprising a removable cover disposed on an upper portion of the chassis. 10. The robot of claim 1 further comprising a removable bumper disposed on a forward portion of the chassis. 11. The robot of claim 1 further comprising a cleaning bin carried by the chassis and arranged to collect debris removed from a work surface by the cleaning head. 12. The robot of claim 11 wherein the cleaning bin comprises: a bin housing defining a debris cavity and a filter cavity, the debris cavity configured to collect debris removed from a work surface by the cleaning head, the filter cavity configured to collect debris removed from a work surface by a vacuum fan in fluid communication with the filter cavity;a bin filter disposed in the filter cavity, the filter configured to substantially inhibit particulate from entering the vacuum fan; anda bin cover attached to the bin housing and configured to move between a bin closed position and a bin open position, exposing the filter cavity and the bin filter for servicing. 13. The robot of claim 12 wherein the cleaning bin further comprises a bin cover spring actuator that biases the bin cover in the open position. 14. The robot of claim 12 wherein the cleaning bin further comprises a latch to hold the biased bin cover in the closed position. 15. The robot of claim 1, wherein the chassis has a first module receptacle and a second module receptacle,the drive wheel assembly configured to be received by the first module receptacle,and the robot further comprises a controller configured to provide independent electrical control to the first module receptacle and second module receptacle; anda display panel connected to the controller, the display panel comprising:a segmented maintenance display substantially mimicking the appearance of the robot; andilluminable indicia disposed on the segmented maintenance display, the illuminable indicia corresponding to the first module receptacle and second module receptacle,wherein the controller is configured to illuminate the indicia on the segmented maintenance display to indicate that a module in one of the first module receptacle and second module receptacle is to be removed and replaced. 16. The robot of claim 15 wherein the display panel further comprises an audio output device controlled by the controller. 17. The robot of claim 1, wherein the chassis is a unibody chassis defining a plurality of module-receiving receptacles, each receptacle having a tool-less receptacle-side electrical plug, the robot further comprisinga controller configured to provide independent electrical control to each tool-less receptacle-side electrical plug; anda fastener that secures at least one module to the chassis;wherein at least one of the receptacles is configured to receive a drive wheel assembly of the multiple drive wheel assemblies, the drive wheel assembly readily removable from the chassis as a complete unit when the fastener is released, the wheel drive motor being connected to a tool-less module-side electrical plug that mates with a corresponding receptacle-side electrical plug; andwherein at least one of the receptacles is configured to receivethe cleaning assembly with the cleaning drive motor connected to a tool-less module-side electrical plug that mates with a corresponding receptacle-side electrical plug.
