目的：

实现其他标准/非标准机器人的构建

案例一：

成果展示

添加机器人JAKA ZU 7 这个模型

具体步骤：

URDF文件准备

从 github 或机器人官网，下载 urdf 模型以及对应的 mesh

xml文件生成

官方提供的 urdf 模型如下：

<?xml version="1.0" encoding="utf-8" ?>

</robot>

修改最下面，将 gazebo 改成：

    <mujoco><compiler meshdir="/home/idm/Downloads/jaka_robot_v2.2/src/jaka_description/meshes/jaka_zu7_meshes/" balanceinertia="true" discardvisual="false" /></mujoco>

注意修改下 meshdir 的路径。

然后执行 ./compile urdf robot.xml，实现 urdf 到 xml 的转变，后续操作之需要在 xml 的基础上修改即可；

xml修改

原始生成的文件如下：

</mujoco>

首先把 compiler, size 这两行去掉，没用了，然后把 asset 中的 file 修改下路径即可；
增加代码

<actuator><motor ctrllimited="true" ctrlrange="-150.0 150.0" joint="joint_1" name="torq_j1"/><motor ctrllimited="true" ctrlrange="-150.0 150.0" joint="joint_2" name="torq_j2"/><motor ctrllimited="true" ctrlrange="-150.0 150.0" joint="joint_3" name="torq_j3"/><motor ctrllimited="true" ctrlrange="-28.0 28.0" joint="joint_4" name="torq_j4"/><motor ctrllimited="true" ctrlrange="-28.0 28.0" joint="joint_5" name="torq_j5"/><motor ctrllimited="true" ctrlrange="-28.0 28.0" joint="joint_6" name="torq_j6"/>
</actuator>

在 link_6 后面加上 right_hand

 <body name="Link_6" pos="0 0.107 0" quat="0.707105 -0.707108 0 0"><inertial pos="2.7652e-05 -1.3485e-05 -0.021245" quat="-0.0453216 0.705107 0.0468242 0.7061" mass="1.4169" diaginertia="0.0011337 0.00072384 0.000718438" /><joint name="joint_6" pos="0 0 0" axis="0 0 1" limited="true" range="-6.28 6.28" /><geom type="mesh" contype="0" conaffinity="0" group="1" rgba="0.84706 0.84706 0.84706 1" mesh="Link_6" /><geom type="mesh" rgba="0.84706 0.84706 0.84706 1" mesh="Link_6" /><body name="right_hand" pos="0 0.098 0" quat="0.707 -0.707 0 0" ><!-- This camera points out from the eef. --><camera mode="fixed" name="eye_in_hand" pos="0.05 0 0" quat="0 0.707108 0.707108 0" fovy="75"/></body>
</body>

截止到此，该机器人配置文件可用了。
