Overview
The tune_camera script provides an interactive tool for adjusting camera positions and orientations in a MuJoCo environment using keyboard controls, outputting the resulting XML camera tag for use in environment definitions.
Description
This script allows users to interactively position and orient cameras in a robosuite environment using keyboard controls, then outputs the corresponding MuJoCo XML camera tag that can be copied into arena or environment XML files. The user can either paste an existing camera XML tag, provide a camera name, or use a default example for the frontview camera in the Lift environment.
The KeyboardHandler class uses the pynput library to capture keyboard events and translates them into camera movements via the robosuite CameraMover utility. WASD keys control camera translation (forward/backward/left/right), R/F keys move the camera up/down, arrow keys rotate the camera view direction, and period/slash keys roll the camera. Movement and rotation deltas are defined as module-level constants (DELTA_POS_KEY_PRESS = 0.05 and DELTA_ROT_KEY_PRESS = 1 degree).
The script accounts for the difference between world-frame camera coordinates and the camera's local coordinate frame defined in the XML file. It computes a transformation matrix between these frames at initialization and applies it when outputting the final camera tag. Every 500 simulation steps, the current camera position and quaternion are printed as a ready-to-copy XML tag.
Usage
Use this script when defining new camera views for robosuite environments or arenas. It is a development utility for finding camera positions and orientations that provide useful viewpoints, then exporting the resulting XML tag for inclusion in MuJoCo model files.

Usage Examples
# Tune the frontview camera in the default Lift environment
# python robosuite/scripts/tune_camera.py --env Lift --robots Sawyer
# (Then paste a camera tag or press Enter for the default example)
# Key controls during execution:
# w/s: Zoom camera in/out
# a/d: Pan camera left/right
# r/f: Pan camera up/down
# Arrow keys: Rotate camera view direction
# ./slash: Roll camera clockwise/counterclockwise
# Example camera tag input:
# <camera mode="fixed" name="frontview" pos="1.6 0 1.45" quat="0.56 0.43 0.43 0.56"/>
