Testing and calibration of row offset when weeding in opposite direction
Problem description - Test procedure - Result evaluation
PROBLEM DESCRIPTION
When weeding in opposite direction one of the key parameters is that the robot runs in the correct track and spacing of the seeding and weeding units on the frame is correct. If this is not the case, then the basis for a successful result is not present.
TEST PROCEDURE
The following test can be performed either on a test field or on real farming field. In both cases, it is fundamental to see the tracks of the wheels of the robot and of the single trailers.
STEP 1
Let the robot drive into a pass located in a flat area of the field.
If the robot is not placed into the field:
-
- Select "weeding" as operation
- Drive it manually into a pass
- Ensure the robot is pointing towards the correct driving direction, according to the settings
- Select "make pass from here" in the route menu
- Calculate the new route
STEP 2
Let the robot drive autonomously for circa 30 meter in the pass, then stop it.
STEP 3
Turn the robot manually so that it faces the opposite direction in the same pass
STEP 4
Select the opposite driving direction in the route calculation menu, select "make pass from here" and calculate the new route
STEP 5
Start the robot and take a close look at the position of:
- Front and rear wheels
- Active and passive trailers
make sure all drive in the same spots (see videos below for ideal results)
STEP 6
If the field has a lot of hills, repeat steps 1 to 5 in a spot with side slope in relation to the driving direction
RESULT EVALUATION
| WHEEL TRACKS | TOOL TRACKS | REASON | |
| CASE 1 | Aligned in flat area | NOT aligned | Tool alignment has to be checked. |
| CASE 2 | NOT aligned in flat area |
1- Check mechanical integrity of the robot steering system 2- IMU calibration required --> contact FarmDroid |
|
| CASE 3 | NOT aligned with side slope | IMU calibration required--> Contact FarmDroid |
CAUTION ⚠️
if your robot has a special configuration that is not symmetrical, please contact FarmDroid Care for further information on how to proceed.
