Work at Aarhus University in Denmark hopes to produce a bolt-on accessory package for mowing robots to provide both simple weeding tools and possibly even lasers for zapping undesirable plant growth. The system can also be used to dispense chemicals in a very focused way in order to reduce environmental impact. Hortibot is not completely autonomous but still claims an improvement in work efficiency. The project list includes squeezing Hortibot's Linux-based controller into the size of a credit card, and allowing a mobile phone to retrieve system status - iMow anyone?
