Developing agricultural robots is challenging due to unstructured environment, lack of GNSS availability, and low income from majority end-users (farmers). To overcome these problems, INESCTEC developed cost effective, modular and reliable localization (works with/without GNSS available) and path planning systems (aware of soil compaction and robot center of gravity). This code is close source and we intend to make it opensource and maintainable by reviewing, optimizing the code, and test it in real conditions. The main outcome will be a open source for ROS Stack (AGROBIT) that will enable cost-effective mowing robot for steep slope vineyards.
