The Volvo Digger of Mars.

If one considers the possibility of going to live on a planet other than the earth, Mars for example, one should also consider the construction of automatics machines to prepare the future planet, at the arrival of the man. That's why I built a prototypes among the most indispensable on the various constructions sites.

 The digger, the indispensable machine by excellence. this big excavators is used in many ways:

Digging of trenches, holes, foundations
Material handling
Forestry work
Demolition 

I used a power set that installs on the tracks so that the Digger can be controlled remotely.
