Hello everyone, while using Isaac sim, I have some doubts about simulating friction that cannot be resolved.
I want to simulate the phenomenon of a car encountering smooth ground and slipping wheels while traveling on the ground.
I set the red ground and friction (both dynamic and static friction are 1). The friction force on the green ground is 0. The ‘Friction Combine Mode’ is’ multiple ‘(I have also tried using’ min ‘and’ average '), but the results are the same.
When the car started on the red ground and reached the green ground (with zero friction), it did not slip but smoothly passed through, as if friction had no effect.
When I put the car on the green ground and started it from friction 0, it experienced skidding.
When I click “play” to simulate, it seems to only simulate the current ground, while ignoring the friction and physical simulation of other ground in the later stage.
I adjusted the dynamic and static friction of the wheels, and the result was the same.
The simulation of friction does not seem to update in real time, which is very unfriendly to physical simulation and cannot fully simulate the real physical world. I would like to know how to simulate the situation of wheel slip during the implementation of the car.
