Pitch #21 - FIRA 2019

1. How does robotics provide solutions to the
constraints of field crop monitoring?
December 11,
2019

2. Observation and expectations
Aims
2
Monitoring crops
growth
Detection of potential
biological threats
Image
resolution
Means
Full plot
Temporal
resolution
Features
All types of
wheather
Scouting
robot

3. Robot SentiV – prototype
Technical specifications :
 Spoked wheels to step over plants
 Modular to adapt to types and growth of crops
 Lightweight = 10kg
 Working area = 20ha a day
 Cameras
- Multispectral (R,G,B,IR)
- RGB (to see under canopy)
 12-hours battery life
3
1m
Data collected :
 Full area scanning
 High resolution imagery
 High time-sequence
 Biological threats under canopy
- Weeds on soil
- Pests and diseases under leaves
How it works :
 Plot contours (CAP)
 Path planning and autonomous
navigation
- Full GNSS
- NRTK soon
 No operator nearby
- Autonomous scanning
- Proximity sensors

4. Data analysis
Images
4
Vegetation indexes
- EVI/NDVI
- LAI, biomass, etc.
- Plant moisture/dryness ->
need other wavelengths in
IR
Biological threats indexes
 Weeds
- Species
- % of covering
 Pests and diseases
- Species
- % of infested plants Spatiale interpolation
(kriging)
Variability
maps
For a better monitoring :
1. Need to know plot’s background
2. Link with other information (ie. soil
profiles, P-rate, N-credit)
3. Should be coupled with agronomic
and climate models
