2.4.2.4 Safety Bumper
The safety bumper (5) (see figure 8 on page 2-14) makes sure the Mixing and Feeding Robot stops when it
hits an object that is at least 45 cm (17.7 in) above floor level. The reaction of the Mixing and Feeding
Robot depends on the object type and the route action
• If the Mixing and Feeding Robot hits a solid object (for instance a tractor), it drives back until there is
no contact with the obstacle. After a few seconds the Feeding Robot tries to continue its route. If it
hits the object again, it drives back again (until there is no contact). This way the Mixing and Feeding
Robot will try to continue its route for a few times and then it stops and generates an alarm message.
• If the Mixing and Feeding Robot hits an object that is not solid, or if a person or animal pushes the
bumper, the vehicle waits a few seconds and tries to continue its route. During feeding the Feeding
Robot will rotate a bit away from the feed fence. If the collision detector is activated a few more times
(within 50 cm (19.6 in)), the vehicle stops and generates an alarm message. The alarm message is
generated after the collision detector has been activated 5 times when the route action is feeding,
during other route action an alarm is generated after 3 times.
2.4.2.5 Safety Key
A safety key (4) (see figure 8 on page 2-14) is installed on the front of the control box of the Mixing and
Feeding Robot.
When the safety key is switched to the OFF position, the Feeding Robot immediately stops operation. The
key operates the same circuit as the emergency button, the same alarm will be generated.
The safety key must be removed before maintenance is done.
