    Chapter 1 Introduction 1 Introduction This manual provides all the information required to use your BM-850 battery powered robotic lawnmower. Your robot uses the system RTK GPS to accurately determine its position at any time. This allows it to mow following a pattern of straight lines and so operate more efficiently than when following a random trajectory.

    Chapter 4 How BM-850 works 4 How BM-850 works The essential elements of your robot's installation are shown in the figure below. Figure 11: Components of an installation 1 The robot The robot contains an antenna that connects with GPS satellites in order to determine its geo-location.

  • Page 19: Leaving The Station

    Chapter 4 How BM-850 works 7 NoGo zone These are areas where the robot is excluded from working. Most typically they contain permanent obstacles, such as plants or buildings. 8 GPS point This is a point known to the robot that it uses for navigation. Most commonly this is to steer it back to the station from the working area.

  • Page 20: Choosing Where To Work

    Chapter 4 How BM-850 works Figure 13: Leaving the station and following a path In this case the robot follows the loop (1) then enters a small safety zone (2) which surrounds a path (3). The robot follows the path until it enters the safety zone where it is to work (4).
  • Page 21 Chapter 4 How BM-850 works Figure 14: Multiple working zones In this example there are three safety zones (1,2, and 3) in which the robot can work, as well as the station loop (4). It is recommended that a working schedule is defined for a robot. This means, for example, that the robot can be configured to only work during a certain number of hours each day.

  • Page 22: Mowing

    Chapter 4 How BM-850 works 4.3 Mowing When the robot leaves the station it will move to the point where it needs to start working. This may be the start of the pattern line where it stopped on the previous cycle (point 1 in the figure below), or the exact point where it stopped (point 2 in the figure below).

  • Page 23: Returning To The Station

    Chapter 4 How BM-850 works Avoiding obstacles when mowing When the robot detects an obstacle when working in pattern mode, it will move backwards and try to navigate around it using small changes in angle. If this is successful, it will continue along the path it was following.
  • Page 24 Chapter 4 How BM-850 works Figure 18: Returning to the station loop In the case where there is more than one GPS zone, the robot will move towards a GPS point that will lead the robot into a zone that is nearer to the station.
