UR5_gripper_camera_gazebo（无moveit）
视频讲解
B站-我要一米八了-抓取不止！Ubuntu 18.04下UR5机械臂搭建Gazebo环境｜开源分享
运行步骤
1.创建工作空间
catkin_make
2.激活环境变量
source devel/setup.bash
3.1 rviz下查看模型
roslaunch gjt_ur_description view_ur5_robotiq85_gripper.launch
3.2 gazebo下仿真
roslaunch gjt_ur_gazebo ur5.launch
4.查看相机内容（RGB,Depth）
rqt_image_view
遇到的报错
1.缺少依赖包
CMake Error at /opt/ros/melodic/share/catkin/cmake/catkinConfig.cmake:83 (find_package): Could not find a package configuration file provided by “object_recognition_msgs” with any of the following names: object_recognition_msgsConfig.cmake object_recognition_msgs-config.cmake Add the installation prefix of “object_recognition_msgs” to CMAKE_PREFIX_PATH or set “object_recognition_msgs_DIR” to a directory containing one of the above files. If “object_recognition_msgs” provides a separate development package or SDK, be sure it has been installed. Call Stack (most recent call first): gripper_breakdown_solution-master/gazebo_plugins/household_objects_database_msgs/CMakeLists.txt:11 (find_package)

解决方法
安装对应的ROS控制包
sudo apt-get update
sudo apt-get install ros-melodic-joint-trajectory-controller
sudo apt-get install ros-melodic-position-controllerssudo apt-get install ros-melodic-joint-state-controller
sudo apt-get install ros-melodic-effort-controllers
http://gazebosim.org/models/地址已经变换http://models.gazebosim.org，因此无法下载所需模型
下载Gazebo模型到本地~/.gazebo/models
cd ~/.gazebo/models/
wget http://file.ncnynl.com/ros/gazebo_models.txt
wget -i gazebo_models.txt
ls model.tar.g* | xargs -n1 tar xzvf
grasp-fix插件加载了两次，查看夹爪的urdf文件，发现下载的夹爪功能包中robotiq_85_gripper.urdf.xacro文件也加载了gazebo_grasp_fix插件，将其注释掉
设置gazebo环境变量
