Title: System for determining position for mobile robot and system for robot returning to charge stand, method for using such systemsApplicant: Ehldzhi Ehlektroniks Ink (KR)Patent number: RU2309655Publication date: July 10, 2007
Field Mobile robots, systems for determining position for mobile robot.
Substance Mobile robot may accurately determine position of wireless signal source at using wireless signal and it provides possibility for its rapid returning to charge stand without error. System for determining position for mobile robot includes wireless signal source designed for wireless signal irradiation in continuous or cyclic mode; mobile robot including large number of directed antennae used for detecting said wireless signal irradiated by its source. Robot determines direction to wireless signal source with use of rotation angle that is determined by means of directed antennae. Then distance is calculated between robot and said source of wireless signal at using time difference of detecting wireless signal by means of directed antennae.
Effect Enhanced reliability and efficiency of returning robot to charge stand.

Field Robotics, namely autonomous ground mobile robots, autonomous unmanned submerged apparatuses with storage battery power supply. Substance: spent storage battery reservoirs of mobile robot are changed by new ones with the aid of mobile robots-satellites in automatic mode. Waste reservoirs are charged on robot-satellite.
Effect Enhanced autonomy degree, increased walking range of mobile robots.
Title: Robot navigation positioning system and navigation positioning methodApplicant: Hefei Inst of Matter Sciences (CN)Patent number: CN1945351Publication date: April 11, 2007
The invention discloses a system and method for navigating and locating mobile robots. The system includes wireless sensor networks and robots. The wireless sensor network node is composed of a sensor unit, a positioning unit, a wireless module and a power supply module. The robot is mobile and there is a wireless GPS module placed on it. The navigating and positing method is: the wireless sensor network nodes are scattered in the monitoring region to form a wireless sensor network. The robot makes a judgment and correction based on the location and environment information of the wireless sensor network to make a further environmental modelling, locating, path-planning and navigating.
Title: Method for mine sweepingApplicant: G Obrazovatel Noe Uchrezhdenie (RU)Patent number: RU2298761Publication date: May 10, 2007
Field Rendering harmless of mines, in particular, methods for mine sweeping.
Substance The method supposes the presence of an excessive quantity of cheap independent mobile robots-sweepers based on the main self-powered platform. Destruction of mines is ensured due to blasting of the robots- sweepers on it. The gaps appearing as a result of blasting of separate robots- sweepers are restored by the reserve ones based on the main self-powered platform. When the reserve robots- sweepers are exhausted, the density of the row of moving robots-sweepers is restored due to the decrease of the mean density of it.
Effect Enhanced efficiency and safety of the process of mine sweeping due to the possibility of self-restoration of the group of the robots-sweepers by the reserve ones and use of remote control.
Title: Intelligent scarecrow system for utilization in agricultural and industrial applicationsApplicant: D. Andrea Paul (CA)Patent number: US2007163516Publication date: July 9, 2007
A bird, animal or the like deterrent system for monitoring and protecting an area from intrusion to be utilized in agricultural and industrial applications comprises one or plurality of vision control units, one or plurality of mobile robots, and one or plurality of wire tracks for the robots. The system is not prone to bird habituation such as static bird deterrents such as scare balloons, bird bangers loud speakers and predator decoys. It combines both movement and localized sounds to scare birds. It is easy to install and easy to maintain.
Title: Safety system designed to prevent collisions between individuals and static or mobile robots, compares their relative positions, warns of impending hazard, and shuts down if appropriateApplicant: Reis GMBH and CO KG Maschinenf AB (DE)Patent number: DE102005037650Publication date: February 8, 2007
The position of a person in the defined region is continuously registered using a navigation system. The position of the person in the defined region is compared with that of the defined safety zone associated with each robot. On approaching and/or entering the safety zone, in accordance with pre- allocated safety parameters of the robot, it is reduced to a safe state or switched off. Other possible defensive actions are described, e.g. robot actions are slowed down. An independent claim is included for the corresponding system.

Field The invention refers to robotics and designated for definition of spatial position on the all three Cartesian coordinates and an angular orientation at its displacement along the surfaces close to horizontal, for example along the floor coverings of manufacturing facilities.
Substance This information is necessary for identification of the position and the angular orientation of a robot. The mode is in installation of three static beacons on an area with the in parallel to the plane of prescribed absolute Cartesian system of coordinates in which two axles are directed in parallel to the plane of displacement of the trolley and one axle is perpendicular to it. Their centers with the known absolute coordinates are located in the plane of displacement of the trolley, on the trolley a local Cartesian system of coordinates with a center which is on the given height in relation to the flat surface is chosen and three sensors are installed on the trolley. The angles of declination relatively to the local plane of displacement of the trolley and the angles of the turn relatively to this plane of position of the beacons are defined, after that approximate absolute coordinates of the center of the trolley are calculated and the turning angle around the vertical axle at assumption that the sensors are located in the center of the trolley and then at initial approximation the refined absolute coordinates of the center of the trolley and the angles of the turn of the trolley around three axles are defined by the way of iterative numeric solution of the system of equations.
EffectProvides possibility of automated refinement of the spatial position on the all three Cartesian coordinates and the angle orientation on the all three possible directions of rotation around the axles of the trolley of a mobile robot.
