feat(arduino): impl robust serial connector with pydantic and extende…

[emrhnyz]

Overview

This PR refactors the move_serial_arduino connector to improve robustness and expands the movement capabilities for serial-based robots. It introduces Pydantic for configuration validation and fixes an import path issue.

Type of change

• Bug fix
• New feature
• Documentation improvement
• Bounty issue submission
• Other: Refactor

Changes

• Refactored serial_arduino.py: - Implemented Pydantic configuration schema for validation (baudrate, timeout).
  • Added robust error handling (try-except blocks) to prevent crashes when the serial port is unavailable.
  • Replaced hardcoded values with configurable fields.
• Expanded Interface: - Updated interface.py to support locomotion commands: WALK, TURN_LEFT, TURN_RIGHT, DANCE.
• Bug Fix: - Corrected the import path in the connector to point to the local extended interface (actions.move_serial_arduino.interface) instead of the base module.

Checklist

• Code complies with style guidelines
• Self-review completed
• Documentation updated (if applicable)
• Local testing completed
• Tests added/updated (if applicable)

Impact

These changes ensure that the serial connector does not crash the system when hardware is missing and allows developers to use OM1 with standard Arduino-based wheeled robots (walking/turning) reliably.
