    Lego Implementation

The series of Rovers presented here are my attempts to model the functionality of Rover Systems as employed on the Sojourner and MER class of rover. Obviously not everything can be modeled in LEGO® , and the Mindstorm/Technic range has inherent limitations. However a quite functional and autonomous Rover can be built using standard, (and some custom) LEGO® components which exhibits the same mechanical and functional design characteristics as the original Rovers.



YogiBearThe chart below summarizes the key systems found in an exploration rover and their application in my 'Yogi' series of Rovers.
