Abstract: A method is disclosed for improving a mobile robot that is configured to perform a task in an environment using an operating procedure. Data is received that was recorded by the mobile robot using one or more sensors as the mobile robot navigates the environment to perform the task. A database and/or a model associated with the environment is updated to incorporate the recorded data. The operating procedure of the mobile robot can be modified, based on the database and/or the model, to generate a modified operating procedure for performing the task in the environment that improves a performance of the mobile robot. Additionally, a recommendation for improving the performance of the mobile robot when performing the task in the environment can be determined, based on the database and/or the model, and displayed to a user for consideration.

Abstract: A modular robot is provided. The modular robot includes a sweeper module having a container for collecting debris from a surface of a location. The sweeper module is coupled to one or more brushes for contacting the surface and moving said debris into said container. Included is a robot module having wheels and configured to couple to the sweeper module. The robot module is enabled for autonomous movement and corresponding movement of the sweeper module over the surface. A controller is integrated with the robot module and interfacing with the sweeper module. The controller is configured to execute instructions for assigning of at least two zones at the location and assigning a work function to be performed using the sweeper module at each of the at least two zones. The controller is further configured for programming the robot module to activate the sweeper module in each of the two zones. The assigned work function is set for performance at each of the at least two zones.

Abstract: An automatically moving floor treatment appliance has an appliance housing, a drive, a detector for detecting surrounding area features, and a computer that transmits control commands to the drive, based on the surrounding area features detected by the detector. The detector has a plurality of inner and outer fall sensors arranged on an underside of the appliance housing, which detect a distance of the floor treatment appliance from the surface. The computer controls the drive to change a movement of the floor treatment appliance when the distance detected by the fall sensor is greater than a threshold value defining a slope. The fall sensors are interconnected in an evaluation circuit of the detection means so that the detection signals of the totality of inner fall sensors can be evaluated independently of the detection signals of the totality of outer fall sensors.

Abstract: Some aspects provide a method for instructing operation of a robotic floor-cleaning device based on the position of the robotic floor-cleaning device within a two-dimensional map of the workspace. A two-dimensional map of a workspace is generated using inputs from sensors positioned on a robotic floor-cleaning device to represent the multi-dimensional workspace of the robotic floor-cleaning device. The two-dimensional map is provided to a user on a user interface. A user may adjust the boundaries of the two-dimensional map through the user interface and select settings for map areas to control device operation in various areas of the workspace.
