Abstract: An autonomous robot is provided, that includes a main body having a frame that includes a back end and a front end. The frame includes a first frame extension and a second frame extension that connects the back end of the frame to the front end of the frame. The front end of the frame includes a path to an open volume disposed between the first frame extension, the second frame extension and the back end. Further provided is a drive system connected to the frame, a retention system coupled to the frame, a lift mechanism attached to the frame, and a sweeper attachment having a dimension to substantially fit within the open volume of the main body. The sweeper attachment is connectable to the retention system to raise and lower of the sweeper attachment using the lift mechanism. Further provided is a controller interfaced with the drive system, the retention system and the lift mechanism. The controller is configured to activate the retention system to connect the frame with the sweeper attachment when the main body is disposed over the sweeper attachment and the sweeper attachment is disposed substantially within the open volume. The drive system is controlled by the controller to move the autonomous robot and activate the sweeper attachment to cause sweeping of a surface.

Abstract: Methods and software for setting parameters for operating a modular robot are disclosed. One method includes receiving, by a server, communications data from a controller of the modular robot. The modular robot has storage for storing program instructions for executing autonomous movement at a location. The method includes sending, by the server, calibrated mapping data for the location. The calibrated mapping data identifies an outline at the location. The method includes sending, by the server, identification of at least two zones at the location, where the at least two zones define different areas at the location. The method includes sending, by the server, a work function to be performed by the modular robot for each of the at least two zones. The work function in each of the at least two zones set to be different at said server. The controller of the modular robot is configured to use the calibrated mapping data for said autonomous movement at the location and the controller is configured to operate said respective work function in each of the at least two zones. The work function can be to sweep, to scrub, to polish, to mow or to perform different work functions over zones of a location, and providing remote access to view real-time operation of the modular robot, and to program zones and other control parameters of the modular robot.

Abstract: An autonomous sweeper is provided, including a sweeper module, and a robot chassis having a length along a pair of sides, a front side, a back side and a top side that define an interior space. The sweeper module is configured to fit within the interior space when the robot chassis moves over the sweeper module. A pair of wheels is disposed proximate to the back side of the robot chassis and a single wheel is disposed proximate to the front side. A pair of scissor lifts is disposed along said pair of sides. A lift frame including alignment pegs that fit into corresponding alignment holes is disposed on the top side of the sweeper module. The lift frame is raised and lowered by said pair of scissor lifts, and said scissor lifts assist in lifting the sweeper module while aligning said sweeper module to the robot chassis using said alignment pegs and alignment holes.

Abstract: An autonomous modular robot includes an attachment retention system that for retaining two or more interchangeable attachments for performing unique tasks, e.g., steam cleaning, vacuuming, grass cutting, etc. The attachments may be sequentially positioned in the path of travel of the robot and configured to perform complementary tasks. For example, for cleaning a floor, a first attachment may be configured to vacuum the floor and a second attachment may be configured for steam cleaning the floor. The robot may also include a vertically translatable lift mechanism. The lift mechanism may include the attachment retention system, thereby allowing the attachments to be moved vertically. The lift mechanism may also include a dimension sensor proximate a top of the lift mechanism. The dimension sensor may be utilized to determine the size, e.g., a height and/or a width of the robot with any retained attachments, to help navigate the robot and avoid obstacles.
