Here is the venue of my weeding machine
it is a bit undulating, with different types of weeds and other stuff i don't want to cut (carpet grass, flower, other edible plant). Hence the idea is to 'sixth sense' those objects
Here let's take a look at all the objects
i obviously cannot cut my children pet guinea pig, and the flowering plants that it like to devour. pumpkin and other flowering edible vegetation are not the target
and these are the target to cut
a typical weed that i currently laboriously remove by hand another variant of weed
these weed at the edge are a challenge, partly because they are taller, in addition there is a cement step border that might cause problem for my robot
Challenge
to build a robot that can traverse the garden with sixth sense (aka automated)
I am delighted that i am selected to be a contestant. The first thing is to find out all my existing rovers and see whether they can fit the bill. The first to try is whether they can move in the garden at all (i do know most of them should fail - 
)
Here are them
these are 4WD but the platform is too low and i guess they will easily get stuck
the MiniQ can run the entire field but it is somewhat too fast and hard to maneuver as well Lego looks to be a possible candidate as the build can be customized, just that i need to interface with it special connector
