For the EFITA
Field robot day
14 June: warming up,
The Wageningen Field Robot Event shows a
vision of the future of modern precision agriculture. Right now, a small
revolution is taking place. A new breed of robots will soon be able to carry out
a variety of tasks in row crops, such as weeding, spraying and disease
monitoring. Agricultural robots working in a field, completely autonomous: the
Field Robot Event proves this is possible!
Intelligent robots will compete in 4
navigation in a maize field with curved rows
The robot should cover as much distance as possible
in 3 minutes time while navigating between curved rows of a maize field, making
a head-land turn and returning in the adjacent row. See figure 1 for
illustration. If mother nature is willing to support this task, there won’t be
plants missing in the rows.
This task is all about speed, accuracy and
robustness of navigation and smoothness of operation.

with curved rows.
2. Advanced robust navigation in a maize
field with straight rows
The robot should cover as much distance as
possible in 3 minutes time while navigating between straight rows of maize
plants. The robot should be able to follow a certain pre-defined pattern over
the field. See figure 2. At various places in the maize field, plants will be
missing in either one or both rows over a length of maximally 1 m. A head-land
of only 1.5 m will be available for turning.
Coding of the pattern of
the path through the maize field is done as follows. S means Start, L means
left-hand turn, R means right-hand turn, F means Finish, the number before the L
or R represents the path that has to be entered after the turn. So, 2L means:
enter the second path after a left-hand turn. 3R means: enter the third path
after a right hand turn. The path shown in figure is coded as follows: S, L3,
R2, L1, R1, R3, L2, R1, F.
Competitors may choose from two options:
use a path of which the code is made available upon registration. This path will
be the same for all competitors.
2. use a path of which the code is made
available to the competitors 1 hour before the start of the competition without
having the opportunity to test it in the maize rows.
Clearly and definitely,
good performance using option 2 will be rewarded with more

3. ‘Weed’ – control in a maize
The robot should cover as much distance
within 3 minutes time while navigating between straight rows of maize plants. In
the maize field randomly distributed artificial weeds yellow golf balls have to be
detected. Detection of a ‘weed’ should be demonstrated by producing a clear
signal such as a flash-light or a sound. Additionally, a ‘weed-killing’
operation should be performed on the ‘weed’.
A set of 5 yellow
golf balls that will be used during the event will be supplied to the
competitors when they register.

4. Free style
Robots are invited to perform a free-style
operation. Fun is important in this task but agricultural relevance is
