"Dave, I think you know what the problem is, just as well as I do."
Clearly the author takes absolutely no responsibility for anything dangerous, illegal, destructive, immoral or just plain stupid that anyone does with these notes. Just a word of caution: 40kg robots are dangerous. 200kg petrol-powered robots with blades spinning at 200km/h are almost unstoppable. Think about a small person getting rammed at full speed with one of these. It will make The Walking Dead seem like a romantic chick flick. Think. Please.

Pest Eviction. Easing the kangaroos out of the paddocks, if kangaroos can be differentiated from sheep and alpacas ).
Weed Detection. Mounting a face-down camera and analysing the image to detect weeds.
Weed Removal. Either through spraying or mechanical means (a length of wire like a lowering spring on a motor can dig out weeds without chemical environmental damage).
