Description
Lero 03 is an autonomous field robot with two drive units and a rectangular frame, the bridge, for implements. It is suitable for long-term autonomous use in the field or in field trials with interchangeable implements, e.g. for laser weeding. It also has sensors and software to consistently map and assess plants in 3D while driving. In addition to its permanent plant identification and mapping, an automatic tool change enables the robot to cultivate a large number of different crops autonomously over a long period of time.
Thanks to its high flexibility, the Lero is also an ideal basis for research projects. The use of state-of-the-art robot software enables safe and efficient long-term navigation on uneven terrain.
Drive train type
Electrical drive train, four-wheel drive (4WD) / all-wheel drive (AWD) with four-wheel kinematics. Intelligent four-wheel control with different drive modes.
Characteristics
200 kilograms implement weight and 2,000 watts implement power for e.g. laser weeding, mechanical weeding, seeding or spot spaying.
Navigation system
Nature Robots employs a modular navigation suite tailored for diverse (agricultural) environments:
1. Open field nav for fields and grasslands
2. Horti nav for vegetable production, market gardening, and breeding parcels
3. OrchVine nav for orchards, vineyards, hops, agroforestry, and agri-photovoltaics
4. Mesh nav for forest, hilly vineyards, mining and Moon and Mars
including GNSS/RTK enabled navigation for simple environments and LiDAR and vision-based life-long SLAM for GNSS-denied environments like Agri-PV (farmland with solar panels), some orchards and vineyards, agroforestry and also mining.
AI-based vision combined with 3D laser models enables the recognition of humans, animals, and moving objects, ensuring safe interaction and halting or replanning operations if necessary. Integrated monitoring systems enable tracking of dynamic obstacles, adapting routes in real time. The navigation suite combines precision, adaptability, and advanced AI for robust performance across varied terrains.
