Photos of the improvments I have made to my Sojourner rover.
About this creation
I made improvements to Sojourner many times. At this point, I don't think there is anything else I can do, so I am putting it up on the web. What I have done:
Rebuilt the whole body with a slightly different shape and in yellow, the closest color to gold (its actual color).
Made the APXS a little better.
Made a working rocker-bogie suspension system and a differential (many thanks to rgeiger), so that any combination of up to 3 wheels can be raised up and the body will still stay pretty much parallel to the ground.
And finally, got better, more realistic wheels (thank you again), and made kind of "hubcaps" for them. Most of these pictures were taken before I got the wheels, so look at the photo "new wheels" to see what they look like.
