Hi there. I'm using Ros Indigo with Gazebo2.
I modeled a car with two fixed rearwheels and two steerable (revolute joints) frontwheels using URDF. When the simulation starts the car falls down in the front. If i reduce the mass of the chassis the car won't fall down in the front anymore but starts to bounce. If I reduce the chassis mass to a small number (1kg) it almost stops bouncing.
My guess is, that this joint can only take a certain amount of weight.
How can I resolve this issue? After all my chassis weighs over 500 kg.
Thanks.
