My entry for this year’s Classic Space Pocket Money Contest: The 6855 Exploration Rover with an original Mars Rover “Rocker-Bogie” suspension and my new “Limeuron” colour scheme.
First of all thanks to “The Davids” for repeating this fantastic contest this year. For me there’s no better way to spend some of the free time during the Christmas Holidays :-)).
With the “New Colour Scheme” rule I had to cancel my original idea of building a later CS model in 1979 style. I’ll add that one to the “CSPM” group, later…
The basic idea was to build a rover with the original Mars Rover suspension. This special suspension has always fascinated me, so I started to do some research about it. The suspension is called a “Rocker-Bogie” suspension. When I was looking for photos with the suspension I immediately found photos of Lego models, too ;-)). The center piece is a differential. The first photos I found where from Keith Enevoldsen’s models. One version of the suspension with a differential bar is also included in the official 21104 Lego model of the Mars Rover “Curiosity”. I used a differential gearbox like the “Pathfinder” Rover “Sojourner”.
I was surprised to see that the suspension is quite sturdy. You can swoosh the rover around applying quite a pressure to the wheels without parts falling off. A simulated jump with some “airtime” wasn’t any problem, either.
The colour scheme is based on my favourite Lego colours lime and black combined with the typical white of the Futuron models. The Astronaut has a Futuron uniform with arms in lime colour and a visor in trans neon green. My name for the theme is “Limeuron” – Guess, why …! ;-))
A little sequence of the working suspension:
And the obligatory alternative models built with the parts of the original model:
