5.4 Hardware Abstraction Module

AgiBot X2 AimDK Hardware Abstraction Module – Provides Low-Level Hardware Interfaces and Sensor Data Access

The hardware abstraction module is a foundational component of the AgiBot X2 AimDK, providing abstracted interfaces to the robot’s various hardware devices. It follows the ROS2 standard and supports both C++ and Python, offering developers a unified hardware access interface.

Core Features

  • Sensor Interfaces: cameras, IMU, LiDAR, touch sensors, etc.

  • Power Management: battery status monitoring and power control

  • Hardware Monitoring: device status monitoring and fault diagnostics

  • Data Acquisition: real-time sensor data collection

Interface Specifications

  • Message Types: uses aimdk_msgs and sensor_msgs packages

  • QoS Policy: QoS varies by topic; see each topic table for details

  • Language Support: C++ and Python

  • Message Format: standard ROS2 message format

Safety Notes

Warning

Hardware Interface Limitations

  • Sensor data can be large; manage memory carefully

  • Hardware control must be used carefully to avoid equipment damage
