Design And Function - Husqvarna Automower 310 Technical Manual

5.1 Design and function

5.1.1 Chassis and body
The robotic lawnmower is structured mechanically
around the following major components:
• Body
• Display cover
• Chassis, upper section
• Chassis, lower section
There are two sealing strips between the upper and
lower sections of the chassis, plus a sealing strip
between the upper section of the chassis and the
display cover. It is important to replace these sealing
strips each time the mower is opened.
5.1.2 Circuit boards
There are up to eight circuit boards in the robotic
lawnmower:
• Main circuit board (1)
• HMI circuit board (2)
• GARDENA Smart system board (3, only for
GARDENA Smart system models)
• Front loop sensor circuit board (4)
• Lift sensor circuit board (5)
• Collision sensor circuit board (6)
The circuit boards contain the electronics and
software required to control the mower's functions.
In simple terms this can be described as the main
circuit board gathering sensor signals that are
evaluated by the software and generating control
signals for the motors. The HMI circuit board
collects its information from keys that are pressed
on the keypad and conveys the menu selections
that the user has made to the main circuit board,
which saves them in its memory. These selections
