User Manual, FD20 v2.3

Version 1.2

– December 2021

Before changing to Highly Automated mode, the user should inspect the Robot mechanically to ensure

the safety system is fully functional.

6.3 Remote monitoring and operation

When the Robot is set to Highly Automated mode, it is possible to operate the Robot via the FarmDroid User
Application. From the Application it is possible to see a status of the current operation as well as performing
basic operation such as “Start” or “Stop”. The prerequisite for the simple remote operation is, that the user
actively and physically has set the Robot in Highly Automated mode.

It is not possible to switch between Manual and Highly Automated mode from the FarmDroid User

Application. For safety reasons this can only be done locally on the Robot.

6.4 Robot propulsion overload protection

The propulsion system is protected against overload. In case of abnormally high load, the robot will gradually
reduce the speed down to 350m/h, if necessary, hence limiting the load to an acceptable level. The robot will
automatically increase the speed when the load drops. When the function is active it will be displayed at the
home screen in the HMI.

The conditions on the field such as moist, stones and slopes will affect the load on the propulsion system.
Slopes and especially sideways slopes will increase the load compared to flat areas. Sideways slopes will
cause an uneven load distribution between the left and right side. To reduce this load, the speed reduces
automatically and temporarily, until the load again is acceptable.

To avoid excess load on the propulsion system, the users must ensure to operate within the technical

specifications of the robot in terms of weight and slopes.

6.5 Auto Load controller

If high load continues despite the propulsion overload protection has reduced the speed, and the Auto Load
Controller is on, the Auto Load Controller will temporarily reduce force on the trailers and soil tools, by raising
the hitch gradually, until the load is at an acceptable level. If the load continues to increase, the robot will
stop and send an alarm.

The Auto Load Controller function is only activated if the robot speed has been reduced to 350 m/h by the
overload protection function, and the load continues to be too high. When the load drops, the hitch will
reapply the force to the trailers, to the predefined level and the propulsion speed will increase toward the
predefined level.

If the Auto Load Controller is deactivated, the robot will stop and send an alarm message if the load remains
too high after the propulsion speed has been reduced to 350 m/h.

The Auto Load Controller can be activated/deactivated in the HMI at page:

6.6 Battery Replacement and Charging

The Robot is equipped with two 24 Volt, 120Ah, Lithium batteries. The batteries are connected to the Robot
with plug connectors.

Under normal conditions the excess production from the solar panels, during the day hours, will be used to
charge the batteries. Dependent of the weather conditions and time of year the charging level can vary.
