Rocker-bogie rover suspension in unity?

[Robotengineer]

I am thinking about making a rover part based on the curiosity rover and was wondering if anyone has made rocker-bogie suspension that works in unity? If you have please post a screenshot or the unity package. Thanks.

I have used Magic Smoke Industries robotics parts to create boggies for rovers - lots of fun. I have a massive one with 32 wheels at one point, it gave a real smooth ride.

You can't make a rocker-bogie system without a plugin such as Magic Smoke; A part can only be a single wheel, and parts don't care about the animated movement of other parts, they only respect movement due to joint flex. So you require a mod that implements joints which can rotate freely. You could make MS parts to facilitate the suspension; and wheels that use attachnodes and have rock solid suspensions so that it's all put on the rocker-bogie, or you could make an alternate plugin which does this specifically; but I believe you would still require separate wheel parts I believe.

Side note, because Unity's WheelCollider system uses linecasting instead of actual round things to make the wheels work; and the glitches that happen when the linecast is not perpindicular to the terrain, a rocker-bogie's two linked wheels will behave strangely more frequently than normal.

Thanks! To fix the line casting issue would it be possible to make a plugin that gives a wheel mesh resistance so that you could use Magic Smoke/IR to turn the wheels?

If the rover is heavy enough, you can use something squishy like batteries in the suspension and make a makeshift rocker-bogie, but you'll probably need a plugin if you want this to be the same size as Pathfinder or Curiosity or whatever.

I made one in KSP a few months ago, using Infernal robotics and internal collisions: https://mathers.ovh/me/?custompage=ksp_rover
