NAVIGATION OF AUTONOMOUS MOBILE ROBOTS

An autonomous cleaning robot includes a controller configured to execute instructions to perform one or more operations. The one or more operations includes operating a drive system to move the cleaning robot in a forward drive direction along a first obstacle surface with a side surface of the cleaning robot facing the first obstacle surface, then operating the drive system to turn the cleaning robot such that the side surface of the cleaning robot faces a second obstacle surface, then operating the drive system to move the cleaning robot in a rearward drive direction along the second obstacle surface, and then operating the drive system to move the cleaning robot in the forward drive direction along the second obstacle surface.

Method for operating a cleaning system

A method for operating a cleaning system that comprises at least one self-traveling cleaning device that travels in an environment based on an environment map and carries out cleaning activities. The cleaning device accesses a database, in which multiple cleaning activities are stored. A user accesses the database and defines in advance at least one randomly occurring event, depending on the occurrence of which at least one certain cleaning activity is carried out. The user defines an event-dependent activity scenario and the activity scenario is carried out upon the subsequent occurrence of the defined event. At least one cleaning activity is also scheduled time-dependently, and predefined rules determine whether only the event-dependent activity scenario or only the time-dependently scheduled cleaning activity is carried out if the time of an occurrence of a defined event falls short of a predefined minimum time interval.

Machine control system providing actionable management information and insight using agricultural telematics

A machine control system includes an agricultural work machine having an ECU coupled via a system bus to control engine functions, a GPS receiver, data collector, and specialized guidance system including a stored program. The data collector captures agricultural geospatial data including location data for the work machine and data from the ECU, and executes the stored program to: (a) capture geometries of the farm; (b) capture agricultural geospatial data; (c) automatically classify the agricultural geospatial data using the geometries of the farm, into activity/event categories including operational, travel, and ancillary events; (d) aggregate the classified data to create geospatial data events; (e) match the geospatial data events to a model to generate matched events; (f) use the matched events to generate actionable information for the working machine in real time or near real-time; and (g) send operational directives to the agricultural work machine based on the actionable information.

Coverage planner

Systems and techniques for generating a set of connected segments for a device or system to traverse in order to reach every point of the region (a coverage plan). Nodes defining the region to be traversed define a polygon. The polygon is decomposed into a mesh and a graph of the mesh is generated. The graph may be used to determine a longest funneled path which, in turn, may be used to either optimize for a longest path or to divide the polygon for eroding sides. The longest path and/or erosions are used to define a set of segments. The segments are connected, which in some examples is done via an optimization to minimize an amount of time or energy to traverse all segments and connections. The resultant coverage plan is sent to a system configured to receive the plan and traverse the region.
