    So, after thinking about this a little, I decided to try building a rover with a working rocker-bogie suspension as a proof of concept:

    VRPAB59.png

    It's all built with BG robotics parts, no stock wheels. The only powered parts are the wheel rotors and the two servos at the front used for steering. (I believe Perseverance uses four wheel steering, but I was lazy and only made two of the six wheel steerable for this test rover.)

    The real secret ingredient is the unpowered servo at the back of the rover body and the two grip pads attached to it, highlighted in the screenshot above. The grip pads have same-vessel interactions turned on, as do the four pads on the suspension that they're sandwiched between. What this simple mechanism does is implement the rocker part of the rocker-bogie suspension: it holds the pitch of the rover body at the average of the pitches of the two upper suspension arms on either side of it, thus allowing the body to match the approximate tilt of the terrain below it, even when said terrain is highly uneven:

    Looks good, I might try this myself using slightly different parts but with a similar concept.

    How does the rover remain powered with six motors, are there batteries clipped into the main body?

     

  2. Well this was fun, as my first rover mission I think it went well, I never had any interest in rover missions as I never saw the point in the stock game.

    I tried to launch ingenuity as well, but came across a few issues which were taking a while to fix so didn't launch it.

    This was on PS4 so no mods were used. I linked a video, the rover hits the Duna atmosphere at 5:36.
