Python Developer for MuJoCo Motion Studio

have developed a custom desktop application called ERIC Motion Studio. It is a Python application that controls a simulated Unitree G1 humanoid robot in MuJoCo. The application includes a PySide6 desktop interface, a MuJoCo viewer, and a natural-language motion generation system. The project is simulation only. It is not connected to a physical robot, and it does not use BrainOS, DDS, SDK2, or Raspberry Pi hardware. Current Issue The application launches and runs correctly. Existing built-in gestures (for example "put hand on chin") work correctly. However, I want to add new natural-language commands such as: raise left hand raise right hand lift left hand lift right hand Currently these commands produce: MOTION_PARSE_FAILED NO_MOTION_GENERATED The project has gone through several revisions, and there appear to be multiple copies/backups of the main source file. I need someone to determine exactly which source file the launcher is executing and make the changes in the correct location. What I Need I am looking for an experienced Python developer to: Diagnose the current project structure. Identify the Python file actually used by the launcher. Remove any confusion caused by duplicate project files. Extend the natural-language motion parser. Implement the missing raise/lift hand motion routine if required. Verify the new motions animate correctly in MuJoCo. Ensure all existing features continue working. Test everything before delivery. Environment Python 3.11 MuJoCo PySide6 / Qt macOS Unitree G1 simulation Desktop application Deliverables Fully working source code. Backup of modified files. Short summary explaining what was changed. Confirmation that the new natural-language commands work correctly. Please apply only if you have strong Python debugging experience. Experience with MuJoCo, robotics simulation, or desktop applications is a plus.
