YoD Posted March 20, 2023 Share Posted March 20, 2023 When performing rover testing in the KSC, the wheel behaviour seems unexpected. At 20m/s, everything is rather ok: However reaching 21m/s (approx.) makes the rover drift/bump/salto, and changing the wheel traction level does not seem to have any impact: If rover behavior is not predictable on full flat ground, it can hardly be used in other situations. Maybe one of the reason is that the runaway is not actually flat, but slightly inclined, and going over a specific speed limit creates a collision detection between wheel and ground. However, it should not produce that behaviour. That type of behaviour might also happens with planes, complicating a normal take off. Link to comment Share on other sites More sharing options...
MehJeb Posted March 20, 2023 Share Posted March 20, 2023 No, that's not Runway - that is rover wheels... see here and many other bug reports: Link to comment Share on other sites More sharing options...
YoD Posted March 20, 2023 Author Share Posted March 20, 2023 Pushing the testing, I changed for bigger wheels At 21m/s, they behave better: And then at 24m/s, the drift happens again (for litteral no reason): Link to comment Share on other sites More sharing options...
YoD Posted March 20, 2023 Author Share Posted March 20, 2023 It is actually worse than I thought: I tried to maintain a speed of 10-11m/s, and the same drift continue to happen (with no info or log displayed in anyway). Drift behaviour seems to be based on an amount time passed driving, no matter the speed, which is even more unexpected as there is no way to avoid it.

JoeSchmuckatelli Posted March 20, 2023 Share Posted March 20, 2023 TR 4 pushed by rockets still has traction in the mountains at 35m/s. See my 'lots of wheels' thread Link to comment Share on other sites More sharing options...
