I am on a mission to disrupt the destructive little furry rabbits that are killing my lawn. The dream machine would be a rover that lived on a drive on charger like my rumba does and have some kind of detection system that sees the little bastards come onto my lawn either by motion or IR sensors etc. Once detected the rover would drive a pre programmed path or more sophisticated attack by using sensors to locate the fury little bugger and it would be chased off just by the rover driving towards it. I would love to mount a water canon or something just to make it more fun!! I have a pixihawk controller and the gps etc from a drone that I didn't end up building so I need to pick a base vehicle (lawn that is mowed weekly and is flat terrain) I am not sure how I would go about this. I can't sit up all night waiting for a dam rabbit. I need to make it run a patrol ever 15 min or on sensing something. Any suggestions on how this could be accomplished? My son is starting this fall in his second year of mechanical engineering and I think this would be a fun project for the two of us to work on together. I have a nice 3d printer to make parts and some time to tinker. Help me get Bugs Bunny off my Lawn!!
