Pix Chassis Interface

Overview

Pixmoving chassis are driving-by-wire/DbW chassis, which are compatible with self-driving systems. We had designed an interface for Autoware.universe.

Notice

For the source code, please refer to pix_driver.

Before you can use the interface, make sure you have already installed and launched ros2_socketcan in your workspace.

Role

There are three main functions for Pix Chasssis Interface:

• Translation between CAN frames and pix_hooke_driver_msgs
• Conversion of Autoware commands to pix_hooke_driver_msgs
• Conversion of vehicle status in pix_hooke_driver_msgs to Autoware messages
