My granddad is 82, has alzheimers and emphysema and still tries to mow his two acre yard. My goal is to create a lawn mower that can handle this task for him. The mower will need to be able to avoid flowerbeds and ditches and stay in their yard only. This will be achieved with boundary beacons, proximity sensors, and gps. Navigational sensors will allow it to mow around buildings and fences. It will be fully electric and should dock itself after each run.
