As we could find so many autonomous lawnmower but so expensive I am sure it could be interesting to have an autonomous lawnmower robot that could be used with this concept :
a four wheels robot : http://store.makeblock.cc/makeblock-starter-robot-kit/
with autonomous and remote control electronic parts
using a five motor that will cut the grass. This motor will use cutter blade
allowing to add a solar panel to auto charging the lawnmower that is used
option : timer (to decide to cut the grass only some days at precise hours) + raining detection to get it back to garage + auto-charging garage that also have a solar panel on top
Does somebody already had realised this use ?
