摩擦
为了使对象(例如手指和对象)之间具有适当的摩擦力,需要在 URDF 中调整一些 Gazebo 参数。对于关节 panda_finger_joint1 和 panda_finger_joint2 我们建议设置以下参数:
<gazebo reference="${link}">
<collision>
<max_contacts>10</max_contacts>
<surface>
<contact>
<ode>
<!-- These two parameter need application specific tuning. -->
<!-- Usually you want no "snap out" velocity and a generous -->
<!-- penetration depth to keep the grasping stable -->
<max_vel>0</max_vel>
<min_depth>0.003</min_depth>
</ode>
</contact>
<friction>
<ode>
<!-- Rubber/Rubber contact -->
<mu>1.16</mu>
<mu2>1.16</mu2>
</ode>
</friction>
<bounce/>
</surface>
</collision>
</gazebo>备注
