The layout of the mower is important to get right. Here are a few pointers.
| Point | Description |
|---|---|
| Distance | Keep a distance of at least 200 mm between the BWF coil reciever and the motors. The motors emit noise which are picked up by the coil and creates disturbances. A sure sign of this problem is if the mower starts to rotate in the middle of the lawn where the signal is as weakest. |
| Wheel placement | Metal can disturb the coils so try to avoid placing the wheels right below the coils. One solution can be to use only one wheel inbetween the coils or to have a bow made out of plastic instead. |
| Weight | Try to keep the center of gravity slightly in front of the rear wheels. This provides best possible grip to the wheels and make it easier for the mower to turn. There is of course a balance because you do not want the mower to tip in an uphill slope. |
| Cables | Twist all cables to minimize disturbance signals to the coils. Keep them as short as possible. |
| Controller | We have designed the controller board such that the all power connections are at the back side of the board and all signal connections on the front side. This is of course with the intention of separating them as much as possible. Placing the board in line with this (front pointing towards the sensors) and keeping the cables separated as much as possible with help significantly. |
| Brushless motor | One great advantage with the brushless cutter motor is that the noise emission is much less. |
| Cutter blades | Cutter blades are made out of metal and most of them are magnetic. We have found that if the cutter disk is placed so that the blades pass close to the coils, they can create fake signals. |
