Soil compaction is an important problem in modern agriculture. Agricultural machines tend to become larger and heavier which may severely damage soil structure, particularly if fields are worked under wet soil conditions. Two potential ways to mitigate soil compaction are (1) controlled traffic farming (CTF) where vehicles can only drive on pre-planned tracks, and (2) using smaller and lighter autonomous vehicles. Either of the solutions requires carefully planned paths over the field while they will also benefit from optimizing routes over those paths.
This thesis topic is a continuation of on-going research, both within projects and MGI thesis research on path planning for agricultural purposes. The thesis topic can focus on software engineering aspects and/or application aspects of the work. Below you can find a non-exhaustive list of possible research objectives. Probably we will cooperate with a commercial partner developing an autonomous vehicle for agricultural operations.
Objectives (choose from):
- Increase the efficiency and robustness of path and route optimization
- Include feasible turning manoeuvres in path planning, accounting for machine kinematics
- Path planning on sloping land
- Collision avoidance
- Assess usability of services
- Increase usability of existing services
- To be discussed...
