Big scale landscape mower robot

The idea was to take all the experience we've gained during the past months
and develop a large-scale 'milling machine'. As architects we are using milling
machines quite often to generate our models. This is one step further, we want to
use grass on a nice site and cut our generated 3D models into it. That means
we want to cut a layer, let it grow for a while and cut it again until it turns
into a model.

Therefor we are using a Leica tachymeter for localization, which is typically used for landscape measurement, and a large radio controlled lawnmower, which can climb banks up to 40 degrees. After writing software that can locate and control the movement, we send that thing onto a grass slope. we could send it to specific coordinates. but it is very hard to bring hardware/movement/software/localization together. So it needs another round of thinking... if you are interested to join this project feel free to write me an mail: wartmann{a t}

Too much sunlight to see anything on the laptop screen.

Robot at full speed cutting grass!

Wondering if this will work
