So it seems like what you want to perform is camera-lidar extrinsic calibration. Seems like you have the translations figured out but not the rotation? You can use one of the already available packages that do this for you. Like Autoware's calibration tool autoware_camera_lidar_calibration. This tool will let you select points in an image and corresponding ...

Actually, the HECTOR_NAVIGATION package depends on other packages and one of them is ceres_catkin (https://github.com/tu-darmstadt-ros-pkg/ceres_catkin) which you need to clone and build in your catkin workspace. However, this ceres_catkin further depends on catkin_simple (https://github.com/catkin/catkin_simple), glog_catkin (https://github.com/ethz-asl/...

What is your cycle time, what latency can you accept, what jitter is acceptable by your application. If your requirements can be fulfilled by a PC with a CAN-Open extension, then you can use a ROS CanOpen package (like this) ...

You're not going to get a parent-child relationship with this because it's not a kinematic tree. You've got a four-bar linkage, which is closed chain linkage. The angle that Link 2 makes with Link 1 depends on the angle at AxisX1 AND the distance from AxisX1 to AxisX3 AND the length of bar1 AND the length of link1 AND the distance from Axis4 to AxisX7.

What do you mean by "end of an URDF file"? The last two links (wrist_3_link and ee_link) are connected by a fixed joint. Change the joint type to prismatic and then update the joint properties (joint axis and joint limits). Or do you want to add an additional link to the manipulator i.e. add a new link after ee_link? In that case, define a new link ...

From the error screenshot you posted: Add the installation prefix of "gazebo" to CMAKE_PREFIX_PATH or set "gazebo_DIR" to a directory containing one of the above files. If "gazebo" provides a separate development package or SDK, be sure it has been installed. Since you said that you have gazebo installed, do you have the ...
