How to Build a Walking Mechanical Lego Spider Tutorial
If you have never built a Lego Technic model with legs this is a good tutorial to start with. This model is easy to build and has common parts.

When you add tread to a Lego 4x4 you get maximum traction. It goes through snow, loose dirt, over huge rocks and logs, and it can't high center because the body is tread. It is a tank and a truck. Better than an all tread because the tread and tire have different traction and mechanical characteristics.

It's a Lego tank and a Lego truck in one. It was so much fun to drive last time I had to build it again with some small improvements. It is lighter, stronger and more compact. Powered with SBrick and a 3 cell LIPO.
