Improve Javadoc Documentation for ServoMotorHelper Class

[yrlmanoharreddy]

Description:

The ServoMotorHelper class currently lacks comprehensive Javadoc documentation. To ensure better understanding and usability for future developers, we need to improve the Javadoc comments. The following areas need enhancement:

Class-Level Documentation:

Provide a detailed description of the class’s purpose and usage.
Include a usage example to demonstrate how the class should be used.

Method-Level Documentation:

Ensure that each public method has clear documentation, including:

• The purpose of the method.
• Parameters and their expected values.
• The return value, if applicable.
• Any exceptions that may be thrown.
• The setAngle method should include information about possible exceptions.
  Additional Information:

Verify that the Javadoc comments are consistent with the current implementation.
Regenerate Javadoc after making updates and ensure that the documentation is correctly included in the generated output.

Tasks:

1. Update Javadoc comments in the ServoMotorHelper class.
2. Regenerate Javadoc and verify that the documentation is visible and correct.
3. Check the generated documentation for completeness and accuracy.
