Abstract: A method for energy management in a robotic device includes providing a base station for mating with the robotic device, determining a quantity of energy stored in an energy storage unit of the robotic device, and performing a predetermined task based at least in part on the quantity of energy stored. Also disclosed are systems for emitting avoidance signals to prevent inadvertent contact between the robot and the base station, and systems for emitting homing signals to allow the robotic device to accurately dock with the base station.

Abstract: A method of mowing an area with an autonomous mowing robot comprises storing, in non-transient memory of the robot, a set of geospatially referenced perimeter data corresponding to positions of the mowing robot as the mowing robot is guided about a perimeter of an area to be mowed, removing from the set of perimeter data one or more data points thereby creating a redacted data set and controlling the mowing robot to autonomously mow an area bounded by a boundary corresponding to the redacted data set, including altering direction of the mowing robot at or near a position corresponding to data in the redacted data set so as to redirect the robot back into the bounded area.

Abstract: A robotic vehicle may be configured to incorporate multiple sensors to make the robotic vehicle capable of detecting grass by measuring edge data and/or frequency data. In this regard, in some cases, the robotic vehicle may include an onboard positioning module, a detection module, and a mapping module that may work together to give the robotic vehicle a comprehensive understanding of its current location and of the features or objects located in its environment. Moreover, the robotic vehicle may include sensors that enable the modules to collect and process data that can be used to identify grass on a parcel on which the robotic vehicle operates.

Abstract: In an apparatus for controlling operation of a utility vehicle that is driven to run within a working area, a map is generated by arraying multiple cells in a grid pattern with respect to the working area, area of the working area is calculated based on the generated map, and required work period per unit time period is calculated in accordance with first characteristics with respect to the calculated area. Then user information including the calculated area and required work period are shown to prompt the user to input user's preferred work period and preferred working time of day. Next target work schedule is calculated by distributing the required work period within the unit time period in accordance with second characteristics based on the user's preferred work period and working time of day inputted by the user and work is controlled in accordance with the calculated schedule.

Abstract: An automatic operation vehicle that automatically performs an operation in an operation area is provided. A survey unit acquires the position information of the marker using a first angle between the moving direction and a direction to the marker from a first point through which the vehicle passes during the movement in a constant moving direction, a second angle between the moving direction and a direction to the marker from a second different point through which the vehicle passes during the movement in the moving direction, and a distance between the first point and the second point. The survey unit determines the first point and/or the second point during the movement of the vehicle in the moving direction such that the angle difference between the first angle and the second angle becomes close to 90°.

Abstract: Disclosed is a robotic work tool (100) for use with at least one guiding wire (250; 260) adapted to conduct electric current to generate a magnetic field around the guiding wire. The robotic work tool has a sensing system (510) adapted to detect a strength of the magnetic field, a steering system (540), a controller (530) configured to control the steering system in response to output from the sensing system by means of a feedback control loop (532) so as to cause movement of the robotic work tool along the guiding wire. The controller is configured to determine a measure indicative of a distance between the robotic work tool and the guiding wire, and adjust at least one parameter of the feedback control loop in response to the determined distance measure.
