The problem addressed
Impossibility of manually measuring growth tracking of thousands of saplings in large forestry areas.
Draft mission flow
- 1The robot walks autonomously between sapling rows in the afforestation area; measures each sapling's height and trunk diameter with centimeter precision via LiDAR.
- 2Growth rate curves generated from periodic measurements; saplings growing slower than expected flagged as stress risk.
- 3Leaf health and disease symptoms evaluated with RGB camera; drying or decaying saplings reported.
- 4Site report transmitted to forestry information system; biomass data provided to carbon credit calculation platform.
Proposed hardware
- 3D LiDAR
- HD RGB Camera
- RTK-GPS
- NVIDIA Jetson Orin NX
Proposed software
- Navigation
- Terrain-adaptive autonomous navigation between afforestation area rows
- Model
- Sapling Height/Trunk Diameter 3D Measurement and Growth Rate Trend Analysis
- Integration
- Forestry Information System (GDF) and Carbon Credit Calculation Platform

Values are manufacturer data. Scenario fit is determined by comparing these limits with site conditions.
From scenario to installation
Feasibility is determined by the site survey: floor and route, network coverage, the charging point, intervention responsibilities and the conditions under which the robot must stop. The survey report defines the scope, the constraints and the commissioning steps.
