Hello @yun-goon, I'm Gemini Code Assist¹! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

Summary of Changes

This pull request addresses build errors in the dynamixel_hardware_interface package. The changes include updating the package version, modifying velocity conversion functions, adding a default case to the error string conversion, and adjusting the format specifier in error messages. Additionally, it removes unused parameters in callback functions and updates the changelog.

Highlights

• Build Error Fix: Addresses errors encountered during the build process, ensuring successful compilation.
• Velocity Conversion: Modifies ConvertValueRPMToVelocityRPS and ConvertVelocityRPSToValueRPM functions in dynamixel_info.hpp to remove the unnecessary id parameter.
• Error Handling: Adds a default case to the DxlErrorToString function in dynamixel.cpp to handle unknown error codes.
• Format Specifier Update: Updates the format specifier in fprintf calls within ProcessReadCommunication in dynamixel.cpp from %d to %ld to match the size of the read_data_list_.size() argument.
• Unused Parameter Removal: Removes unused previous_state parameter from on_activate and on_deactivate methods, and unused time and period parameters from read and write methods in dynamixel_hardware_interface.cpp.

Code Review

The pull request addresses build errors and includes several modifications to improve the code. The changes include updating the changelog, modifying the dynamixel info header, updating the package version, adding a default case to the DxlErrorToString function, correcting format specifiers in fprintf calls, removing unnecessary id parameters from conversion functions, adding maybe_unused attributes, and updating the reboot_dxl_srv_callback function. Overall, the changes seem reasonable and address the stated goal of fixing build errors.

Summary of Findings

• Missing ID Parameter in Conversion Functions: The removal of the id parameter from ConvertValueRPMToVelocityRPS and ConvertVelocityRPSToValueRPM in dynamixel_info.hpp and the corresponding changes in dynamixel.cpp raises a concern. It's crucial to verify that these functions don't rely on the id for any internal calculations or data access. If the id is indeed unnecessary, the change is valid; otherwise, it could lead to incorrect behavior.
• Format Specifier Correction: The change from %d to %ld in fprintf calls within dynamixel.cpp is essential for handling the read_data_list_.size() variable, especially if its size exceeds the range of a standard int. This prevents potential data truncation and ensures accurate logging.
• Adding Default Case in DxlErrorToString: The addition of a default case in the DxlErrorToString function within dynamixel.cpp is a good practice for handling unexpected or unknown error codes. This ensures that the function always returns a meaningful string, even if the error code is not explicitly defined.

Merge Readiness

The pull request appears to address the stated goal of fixing build errors. However, the removal of the id parameter from the conversion functions warrants further investigation to ensure that it does not introduce any unintended side effects. I am unable to approve this pull request, and recommend that others review and approve this code before merging. At a minimum, the high severity comment should be addressed before merging.

The id parameter is removed from dxl_info_.ConvertValueRPMToVelocityRPS. Ensure that this function does not rely on the id for any internal calculations or data access. If the id is not used, this change is valid; otherwise, it could lead to incorrect behavior.

	*data_ptrs[item_index] = dxl_info_.ConvertValueRPMToVelocityRPS(

	*data_ptrs[item_index] = dxl_info_.ConvertValueRPMToVelocityRPS(static_cast<int32_t>(dxl_getdata));
	*data_ptrs[item_index] = dxl_info_.ConvertValueRPMToVelocityRPS(static_cast<int32_t>(dxl_getdata));
