1-90: Consider organizing dependencies by environment.The current list includes both runtime and development dependencies. Consider:
- Moving development tools (pytest, pylint, etc.) to a separate
requirements-dev.txt- Keeping only runtime dependencies in the main requirements file
- Using environment markers for Python version compatibility
This would improve maintainability and make the dependency structure clearer.

115-119: Consider consolidating angle normalization logicThe TODO comment indicates that
_norm_anglemight be duplicated across the codebase. Consider extracting this into a shared utility function.Would you like me to help identify all occurrences of this function and create a shared utility module?
robot_sf/robot/bicycle_drive.py (2)
129-129: Good fix for shared state, but consider simplifying the initialization.The use of
default_factorycorrectly ensures each robot instance gets its own unique state object, preventing shared state issues. However, we can make this more readable.Consider replacing the lambda with a class method or standalone function:
- state: BicycleDriveState = field(default_factory=lambda: BicycleDriveState(pose=((0.0, 0.0), 0.0))) + @staticmethod + def _create_default_state() -> BicycleDriveState: + return BicycleDriveState(pose=((0.0, 0.0), 0.0)) + + state: BicycleDriveState = field(default_factory=_create_default_state)This makes the initialization logic more explicit and easier to test.
Create a common angle normalization utility to eliminate code duplication
Found identical angle normalization implementations in:
robot_sf/robot/bicycle_drive.py:_norm_anglerobot_sf/ped_ego/unicycle_drive.py:_norm_angleBoth implementations:
- Use the same algorithm:
atan2(sin(angle), cos(angle))- Have identical docstrings and TODO comments
- Serve the same purpose of normalizing angles to [-π, π]
Recommendation:
- Create a new utility module (e.g.,
robot_sf/utils/angle.py)- Move the normalization function there
- Import and use it in both drive classes
This will:
- Eliminate code duplication
- Ensure consistent angle normalization across the codebase
- Make future maintenance easier

196-196: LGTM! Critical fix for state initialization.The change from
field(default=...)tofield(default_factory=...)is crucial as it ensures each robot instance gets its own unique state.

Consider pinning package versions for reproducible builds
Not specifying version constraints can lead to inconsistent environments across different installations and potential compatibility issues. Consider:
- Pinning specific versions (e.g.,
torch==2.1.0) - Using minimum versions (e.g.,
torch>=2.1.0) - Using version ranges (e.g.,
torch>=2.1.0,<3.0.0)
This ensures reproducible builds and helps prevent unexpected breaking changes.
Let's verify the latest compatible versions of key packages with Python 3.9-3.12:
✅ Verification successful
Based on the verification results, I can now provide specific version recommendations. Let me generate the final response:
Pin package versions to ensure reproducible builds
Based on the latest compatible versions and Python requirements:
torch>=2.5.1,<2.6.0gymnasium>=1.0.0,<1.1.0stable-baselines3[extra]>=2.4.0,<2.5.0shimmy>=2.0.0,<2.1.0- For other packages, use similar version constraints based on your specific needs
This ensures compatibility with Python ≥3.8 while preventing breaking changes from major version updates.

- Follow Python dataclass best practices
Also applies to: 36-38
Line range hint 1-85: Verify Python 3.9 compatibility.
The code appears compatible with Python 3.9, but let's verify there are no version-specific dependencies or features being used.
✅ Verification successful
Let me check the Python version requirements in setup.py to make a final determination.
Code is compatible with Python 3.9
The code in sim_config.py is fully compatible with Python 3.9:
- All type hints used (
List,float,int,bool) are standard typing features available since Python 3.7 - The dataclass implementation uses basic features (
@dataclass,field) that were introduced in Python 3.7 - The project's
setup.pyspecifiespython_requires=">=3.8", confirming Python 3.9 compatibility - No Python 3.9-specific features or future annotations are being used that could cause compatibility issues

22-22: LGTM: Import of field is correctly added.
The addition of field from dataclasses is necessary for the refactoring of dataclass fields.
39-43: LGTM: Proper initialization of dataclass fields.
The use of field(default_factory=...) ensures each instance gets its own fresh copy of the settings objects, preventing the sharing of mutable default values across instances. This is a significant improvement in terms of safety and correctness.
75-75: LGTM: Consistent with parent class field initialization.
The use of field(default_factory=UnicycleDriveSettings) for ego_ped_config maintains consistency with the parent class's field initialization pattern while ensuring each instance gets its own fresh copy.
41-42: Verify behavior with Union type default factory.
The robot_config field uses a Union type but defaults to DifferentialDriveSettings. Please verify that this default is the intended behavior and that the code handles both robot types correctly.
✅ Verification successful
The previous output shows BicycleDriveSettings is used in several places, but we need to verify:
- The robot factory implementation to ensure both types are handled
- Usage patterns of DifferentialDriveSettings
- Test coverage for both robot types
This will help us confirm if the Union type with DifferentialDriveSettings default is properly implemented and tested.
Union type default factory implementation is correctly handled
The codebase properly handles both robot types through the robot_factory method which includes type checking and appropriate instantiation for both DifferentialDriveSettings and BicycleDriveSettings. Specifically:
- The factory method correctly handles both types with proper type checking
- It returns the appropriate robot instance (
DifferentialDriveRobotorBicycleDriveRobot) based on the config type - It includes error handling for unsupported types
- Both robot types are actively used in the codebase, with
DifferentialDriveSettingsas a sensible default

42-42: Verify impact of velocity type change
The velocity field type has changed from float to PolarVec2D. This is a breaking change that may affect existing code.
128-128: LGTM! Improved initialization pattern
Using field(default_factory=...) ensures each instance gets its own state object, which is the correct pattern for dataclasses.
✅ Verification successful
Let me analyze the initialization and reset_state usage further.
Based on the gathered information, I can now generate the final response:
Verified: The default_factory initialization is safe and properly handled
The change to use default_factory for state initialization is well-integrated in the codebase:
reset_stateis properly called in simulator.py when initializing pedestrian positions- The only direct instantiation (in env_config.py) passes required configuration
- The state is properly managed through the pedestrian lifecycle

The previous command didn't properly extract the extra dependencies. Let's try using pip's dry-run to see what additional packages would be installed with the [extra] variant.
Let's check if there's any documentation or setup files that might list the extra dependencies for stable-baselines3.
Dependencies look appropriate for the project's needs
Looking at the project's setup.py and requirements.txt, the dependencies are well-structured and appropriate for the project's needs. The stable-baselines3[extra] package is used alongside other essential dependencies like gymnasium, pygame, numpy, and wandb, which are commonly used with stable-baselines3 for reinforcement learning tasks.

💡 Codebase verification
Add version constraints and remove redundant gym dependency
- The codebase exclusively uses
gymnasium(notgym) in all imports and class inheritance setup.pyalready specifiesgymnasiumas a requirement and Python>=3.9- Key dependencies have compatible Python requirements (all support Python 3.9)
Recommendations:
- Remove
gymfrom requirements.txt as it's not used - Add version constraints aligned with setup.py:
gymnasium>=0.29.0
torch>=2.0.0
stable-baselines3[extra]>=2.0.0
- Keep other dependencies but consider adding minimum versions
🔗 Analysis chain
Consider adding version constraints for critical dependencies
Removing all version constraints could lead to compatibility issues when new versions are released. Consider adding version constraints at least for critical dependencies like torch, gymnasium, and stable-baselines3.
Let's verify the compatibility between these packages:
Let me gather more information about the dependencies by checking setup.py and any other configuration files that might have version constraints.
Let me check the actual usage of gym vs gymnasium in those files to understand if both are really needed.

1-16: Consider adding upper bounds to version constraintsWhile minimum version constraints are good, consider using version ranges (e.g.,
>=1.0.0,<2.0.0) for critical dependencies to prevent potential breaking changes. Some version constraints are very recent and might limit compatibility:

1-2: LGTM: Core ML package versions are compatible
The version constraints for core ML packages (gymnasium, gym, torch, stable-baselines3) are well-specified and compatible with each other. Retaining both gym and gymnasium is intentional as confirmed in previous discussions.

🛠️ Refactor suggestion
Consider separating development dependencies
Testing and profiling tools (pytest, scalene) should be moved to a separate requirements-dev.txt file to keep production dependencies minimal.
Create a new requirements-dev.txt:
# requirements.txt
-pytest>=8.3.3
-scalene>=1.5.48
# New file: requirements-dev.txt
+pytest>=8.3.3
+scalene>=1.5.48📝 Committable suggestion
‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Learning: In the 'robot_sf_ll7' project under full development, it's acceptable to keep all dependencies, including development dependencies, together in the 'requirements.txt' file.
Note: Learnings are effective only in the context of similar code segments. To apply general coding guidelines, please configure review instructions. You can manage existing learnings in the app.

128-129: Consider making the frame rate configurableThe TODO comment suggests making the sleep time configurable. This would be useful for different performance requirements.
Would you like me to help implement a configurable frame rate system? I can generate a solution that includes:
- A new class attribute for target FPS
- A frame rate limiting mechanism using
pygame.time.Clock

77-96: LGTM! Well-structured initialization of dataclass fields
The initialization of class attributes is well-organized, with appropriate use of field(init=False) for PyGame-specific attributes and default_factory for mutable types like lists and numpy arrays.

89-98: LGTM! Good improvements to field initialization.The use of
field(default_factory=...)for mutable defaults and the addition of UI state fields improves the class initialization. The type change fromnp.arraytonp.ndarrayis more precise.Consider adding type hints to the UI state fields for better code maintainability:
- display_robot_info: int = field(default=0) - display_help: bool = field(default=False) + display_robot_info: int = field(default=0, metadata={"valid_values": [0, 1, 2]}) + display_help: bool = field(default=False)
115-133: Consider using PyGame's clock for frame rate control.The current implementation uses a hardcoded sleep duration. PyGame provides better tools for frame rate control.
Consider this improvement:
+ clock: pygame.time.Clock = field(init=False) + def __post_init__(self): pygame.init() pygame.font.init() + self.clock = pygame.time.Clock() def render(self, state: VisualizableSimState): """Render one frame and handle events.""" # Handle events on main thread for event in pygame.event.get(): if event.type == pygame.QUIT: self._handle_quit() elif event.type == pygame.VIDEORESIZE: self._handle_video_resize(event) elif event.type == pygame.KEYDOWN: self._handle_keydown(event) if self.is_exit_requested: pygame.quit() if self.is_abortion_requested: exit() return - sleep(0.01) # limit UI update rate to 100 fps + self.clock.tick(100) # limit to 100 FPS
296-300: Consider implementing image-based rendering for entities.Multiple TODO comments indicate a plan to use images instead of shapes. This would improve visual quality and potentially performance.
Would you like me to help create a new issue to track the implementation of image-based rendering for robots and pedestrians?

529-558: Optimize grid drawing performance.The grid drawing implementation recalculates positions frequently and creates new font objects. This could impact performance with frequent updates.
Consider these optimizations:
+ _grid_font: pygame.font.Font = field(init=False) + def __post_init__(self): pygame.init() pygame.font.init() self.screen = pygame.display.set_mode((int(self.width), int(self.height)), pygame.RESIZABLE) pygame.display.set_caption(self.caption) self.font = pygame.font.Font(None, 36) + self._grid_font = pygame.font.Font(None, 24) def _draw_grid(self, grid_increment: int = 50, grid_color: RgbColor = (200, 200, 200)): - font = pygame.font.Font(None, 24) + # Cache calculations + scaled_grid_size = grid_increment * self.scaling + start_x = ((-self.offset[0]) // scaled_grid_size) * scaled_grid_size + start_y = ((-self.offset[1]) // scaled_grid_size) * scaled_grid_size + + # Pre-render labels + x_labels = {x: self._grid_font.render(str(int(x / self.scaling)), 1, grid_color) + for x in range(start_x, self.width - self.offset[0], scaled_grid_size)} + y_labels = {y: self._grid_font.render(str(int(y / self.scaling)), 1, grid_color) + for y in range(start_y, self.height - self.offset[1], scaled_grid_size)}

209-241: LGTM! Well-structured key handling implementation.
The dictionary-based approach with lambda functions makes the code clean and maintainable. The use of modifiers (Ctrl, Alt) for different movement speeds is a good UX feature.
Update the Python version requirement to 3.9, refactor dataclass fields for better initialization, and include a comprehensive list of installed packages.
