The application of field robotics to agriculture is an emerging area of interest for our researchers. The increasing demands on our agricultural sector are forcing farmers to consider robotic assistance where before they worked alone. In recent years GPS guided tractors have become commercially available and are now seen commonly in many countries in the world. These systems still rely on the farmer to supervise them – normally from tractor’s cab. It is hoped that the next generation of farm robots will be more aware of their immediate surroundings and will be capable of mapping obstacles and navigating autonomously. Unlike field robotics in other domains such as mining or the military (where safety and the removal of people from hazardous situations is a major driver), agricultural robotics will only make sense when the business case means that using robots will save money when compared to farming in a traditional manner.
