  • Page 24: How Big Mow Bm 2050 Works

    Chapter 7 How Big mow BM 2050 works 7 How Big mow BM 2050 works The robot works in a number of 'states'. Within these states it is programmed to operate in a number of 'modes'. Operational state (page 24): In this state the robot operates in cycles in which it works, (cutting the grass), or is in the charging station either to charge the battery or for a rest period.

  • Page 25: Work Mode

    7.1.1 Work mode Figure 21: Work mode When in work mode, Big mow BM 2050 mows the grass in working areas. The RTK GPS positioning system enables the robot to mow the grass following a pattern. Pattern mowing can be disabled and the area will then be worked in random mode.
  • Page 26 Chapter 7 How Big mow BM 2050 works 7.1.1.1 Mowing using a random trajectory Random mowing in a wired parcel Figure 22: Random movement in a wired parcel The charging station emits a signal that generates an electro-magnetic field within the area bounded by the peripheral wire.
  • Page 27 Chapter 7 How Big mow BM 2050 works Figure 23: Random movement within a GPS defined zone The robot will leave the station, turn through an angle and head towards to the centre of the GPS defined zone (A). It will then work in the zone using a random trajectory. It will stay in the zone as closely as possible, but GPS accuracy is +/-10m.
  • Page 28 Chapter 7 How Big mow BM 2050 works Figure 24: Pattern mowing in a simple rectangular working area The robot will exit the station and move towards the working area using the GPS points. Once the working area has been reached the robot will calculate a path to the start point of the pattern for this cycle and will navigate to this point using GPS.
  • Page 29 Chapter 7 How Big mow BM 2050 works During pattern mowing, the robot turns before it reaches the peripheral wire, so the edge of the zone is not mowed. It is important therefore to make sure that the robot mows the border at least 2 times per week.
  • Page 30 Chapter 7 How Big mow BM 2050 works When mowing normally, the robot moves at a speed of about 1m/s (3.5km/h). In areas where the grass is longer, the robot will automatically adapt its mowing mode by slowing down. The robot can detect an obstacle (permanent or transitory) through a set of sonar sensors (page 21).

  • Page 31: Go To Charging Station Mode

    Chapter 7 How Big mow BM 2050 works This does, of course, mean that there is a risk of areas behind the obstacles not being mowed. However, since the direction of mowing changes with each cycle, this may well be remedied on subsequent cycles.
  • Page 32 Chapter 7 How Big mow BM 2050 works Figure 30: Return to station using the station loop At point A, the robot decides to return to the charging station. Note: Point A may be in a wired parcel, as shown above, or in a GPS defined zone associated with the wired parcel.
  • Page 33 Chapter 7 How Big mow BM 2050 works Figure 32: Opposite return directions Once the robot has arrived at the charging station, it enters Charge mode (page 37). 7.1.2.2 Return to station loop from chained fields The default method to return to station involves the robot following the track border. This is shown in the figure below.
  • Page 34 Chapter 7 How Big mow BM 2050 works When the robot reaches point C, it must follow the station loop wire until it arrives at the charging station. The route it takes depends on the return direction defined for the loop parcel.
  • Page 35 Chapter 7 How Big mow BM 2050 works Figure 36: Return to station using GPS These manoeuvres depend on whether the robot is in the parcel nearest to the station (Parcel 1) or whether it is in a neighbouring parcel (Parcel 2) when it needs to return to the station.
  • Page 36 Chapter 7 How Big mow BM 2050 works Figure 37: Matching return directions When the return direction for the parcel loop is opposite to that of the working loop, the robot will take the route shown in the figure below.

  • Page 37: Charge Mode

    Chapter 7 How Big mow BM 2050 works Return to station in a GPS navigation zone When a robot is working within a GPS navigation zone (page 82), it knows its location to a high degree of accuracy. When it needs to return to the station, it will navigate to a GPS point near the station and then follow the station loop wire.

  • Page 41 Chapter 7 How Big mow BM 2050 works Note: The robot may also leave the station to mow the border (page 38). Before leaving the station the robot must decide where to start mowing. See Choosing where to work (page 43).
  • Page 42 Chapter 7 How Big mow BM 2050 works Figure 47: Go zone using GPS into multi-fields When the robot leaves the station it follows the station loop wire, until it reaches point A, within the track border. The direction the robot takes depends on the return direction for the station loop.
  • Page 43 Chapter 7 How Big mow BM 2050 works Figure 48: Exit station with a single wire 7.1.6.4 Exit station into a GPS navigation zone A robot using the RTK GPS system knows its global position to a high degree of accuracy.
  • Page 44 Chapter 7 How Big mow BM 2050 works Working schedule When a schedule is defined, which dictates exactly where the robot should work, the robot will follow the schedule. This will override the percentage of time allotted to a working area.
  • Page 45 Chapter 7 How Big mow BM 2050 works The robot works in Zone G, until the cycle ends when it needs to return to the station to charge. The work in Zone G is not complete. When the robot resumes working, it will ignore the percentage times allotted and return to Zone G to complete the pattern.
