we should probably do this in the env side

robot_infra/env/wrappers.py

This is my first pass of the code review. Overall more work needs to be done for the refactoring (configurable configs, cleaning up of wrappers and env, etc.). Many of the impl can be made common in the FrankaRobotiqEnv, so reduce code duplications in pcb, cable and bin-pick. Also would recommend making this robot_infra as another package.

I can give another review after the first cleanups. Thanks for the hardwork.

Move euler_2_quat and quat_2_euler to a utils.py

This entire code block is quite unreadable. Requires more cleanup (e.g. what is jpos). Add those val (retry_count, tolerance, thresh, etc.) as configs/params and also add comments. type cast jpos: np.narray is always recommended

Now serl is organized as

serl
- franka_sim
- serl_launcher
- examples
- franka_env (TODO, or other names, serl_franka_infra)

Thus, if it make sense try to organize the robot code into a separate pkg, and add executables to examples or scripts

robot_infra/env/franka_robotiq_env.py

+                              if key == 'wrist_1':

Hard coded serial_num again. should have all these in a init_rs() function. All these detailed impl of getting the cam can be placed in rs_capture.py too

robot_infra/franka_server.py

have all these being placed within if __name__ == '__main__':?

Also, if this script flask server script is getting too long, would split both the flask server and "robot ros server" into 2 different scripts. I would also rospy.init_node() the node in the class init.

+                  print("Moving to", pos)

if these print out is getting overwhelming, can consider use logging.debug()
