Description

I have set up a Ros master slave system btw two boards, the master is for moving the franka arm and the slave is stereolabs zed box connect to zed2 camera. I am getting the rostopic of the slave on the master and have used that to calibrate Eye-in-hand between the arm and the camera. this works fine an I have generate a static tf .launch file.

The problem now is that I have calibrate the panda_link8 to zed_base_link. so now when I launch my static generated file, it affect the tf of the zed_wrapper, more like the tf are getting disconnected which stops the object detection of the camera from working

Here are some images for reference

This is the tf image before running the calibrated tf .launch file

Here's the tf after starting the static transform. it seems map -> odom -> base_link got disconnected from the zed_wrapper tf tree

This is preventing the camera from working, if I stop the static calibrated tf the camera works fine

Steps to Reproduce

  1. Set up a master-slave connection between both boards,
  2. Calibrate the arm pand_link8 to zed_base_link using moveit calibration too from here
  3. Make a lunch file from the calibration and run it, it should mess with the tf of the zed_wrapper.
    ...

Expected Result

The camera should work along with the static tf, I need it in order to transform the coordinate from the camera for the arm to move to the location of the X,Y,Z

Actual Result

The static transform is messing with the zed_wrapper transform

ZED Camera model

ZED2

Environment

Environment is a master-slave configuration of two different boards
The zed board orin nx running OS ubuntu 20.04 connect with the camera acts as the slave
The master is AAEON UPX-TGL01 from the UP Xtreme Series from Intel running OS 20.04 is connected to the arm

Anything else?
