I want to simulate two differential drive robots carrying a box above their chassis. But I am having some trouble on the simulation because the box is vibrating when above the robots.

This is the sdf from the box, am I doing something wrong or is this expected? How could I correct it?

<sdf version="1.4"> <model name="box"> <static>false</static> <link name="chassis"> <pose>0 0 0 0 0 0</pose> <inertial> <mass>0.01</mass> <inertia> <ixx>0.001666666</ixx> <ixy>0.0</ixy><iyy>0.001416666</iyy> <ixz>0.0</ixz><iyz>0.0</iyz><izz>0.001666666</izz> </inertia> </inertial> <collision name="collision"> <geometry> <box> <size>.1 .4 .1</size> </box> </geometry> <surface> <friction> <ode> <mu>10000</mu> <mu2>10000</mu2> </ode> </friction> </surface> </collision> <visual name="visual"> <geometry> <box> <size>.1 .4 .1</size> </box> </geometry> </visual> </link> </model> </sdf>
