Abstract:
An unmanned tactic platform (UTP) mounted on a two-stage locomotive system of which a first locomotive stage is a significantly high-speed travel stage where the UTP reaches an arena, and a second locomotive stage is a tactical maneuver stage in which the UTP maneuvers at the arena for executing a mission.
Abstract:
Each partial object of the unit, e.g. go from A to B, keep the uncertainty of your position below a given threshold, or draw up a map of the area and insert these landmarks into it, is allotted different bonuses and penalities. Performance weightings for the individual objects are found in connection with the need to perform them after an analysis of the bonuses and penalities and they are evaluated in a control unit. In the context of the process, a local planning horizon is given in which the environment of the unit is divided into grid cells. Preferred directions are stored for these grid cells which lead the unit to the shortest route to already known or unconfirmed landmarks in order to reduce the positional uncertainty or confirm a landmark. All the various routes possible within this grid are examined to find their contribution towards enabling the unit to reach the goal. Here, the sum of the costs and usefulness of each partial object along each route is formed. That route is chosen which results in the greatest usefulness or the smallest loss. The cyclical performance of the process finally results in a target lying outside the local planning horizon.
Abstract:
The invention describes a device and a process for exploring an unknown working area. It is not necessary for this purpose to make any markings in the area before using the device and the area does not have to have any special characteristics for determining location. The described device of the invention takes markings with it, for example metal plates or a power supply cable which it lays out while it moves around a boundary of the area. It then turns around and moves back along the marking, laying out new markings. On encountering the next wall of the area it turns, takes up the previously laid out markings and lays new ones. This process continues until the entire area has been covered. An example of the use of the device could be an industrial vacuum cleaner for cleaning carpeted floors.
Abstract:
A solution for estimating the pose of a platform, such as a vehicle, is provided. Data from a plurality of types of sensing devices located on the platform can be used to independently calculate a plurality of preliminary estimates corresponding to the pose. A plurality of estimates corresponding to the pose can be generated using the preliminary estimates and at least one covariance matrix. One or more entries in the covariance matrix are adjusted based on an uncertainty for the corresponding preliminary estimate. The uncertainty can vary based on time, distance, and/or velocity of the platform.

Abstract:
An object of the invention is to provide a new defect detection technique using an autonomously movable apparatus. In order to accomplish the object, the invention provides a detection system (10) including a drive control unit (15) that controls a driving unit (12) causing a base unit (11) to travel in a case where a predetermined detection target is detected on the basis of information collected by a sensor unit (13) installed in the base unit (11), and a second detection unit (16) that detects a predetermined defect on the basis of the information collected by the sensor unit (13).
Abstract:
A robot cleaner includes an environment information detecting unit configured to obtain environment information regarding at least a portion of a cleaning area, a first communication unit configured to transmit and receive data to and from a different device positioned within the cleaning area, and a control unit configured to generate a control command regarding the different device in order to adjust the obtained environment information.
Abstract:
The invention relates to a device (100) for visually inspecting the external surfaces (90) of an aircraft, which comprises an inspection area for receiving an aircraft, at least one visual inspection robot (10), and a control center (50). A movable platform (11) of the robot supports a turret (12) having observing means (13). The robot comprises processing means (20) which guide the movable platform (11) and process the data received from the observing means (13). The processing means (22) of the robot are suitable: for autonomously controlling the robot (10) during the visual inspection of the external surfaces of an aircraft (9) parked in the inspection area; for interrupting a visual inspection in the event of a detection of an anomaly on the external surface of the aircraft; for transmitting visual inspection data to the control center; and for receiving instructions from the control center.
