Motor Node

This node manages motor control with configurable controller backends. It provides velocity control through the standard /motor/cmd_vel topic and publishes odometry data.

Controller Selection

The node supports multiple motor controllers, selected via configuration:

• mock: Simulated motors for testing/development (no hardware required)
• l298n: L298N dual H-bridge driver for DC motors

Topics

• Subscribes: /motor/cmd_vel (Twist) - Velocity commands
• Publishes: /odom (Odometry) - Odometry data
• Publishes: /motor/status (MotorStatus) - Motor status
