问题1:

  • moveit_setup_assistant配置后,launch demo.launch.py后不能显示机械臂模型。

解决1:

  • 修改moveit_config/config/joint_limits.yaml,将 max_velocity: 100改为max_velocity: 100.0000000000000001。这是一个待解决的软件本身bug。

问题2:

  • rviz中可以plan,但是Excute后Failed。

解决2:

  • 修改moveit_config/config/moveit_controllers.yaml,在其中添加以下内容:
action_ns: follow_joint_trajectory
default: true
