dora-kit-car control

Introduce

Dora Kit Car is a DORA node for controlling a differential-drive mobile robot to move forward/backward and turn left/right. Developed in Rust with Python API support.

Highlights

  • Compatible with the ROS geometry_msgs/Twist.msg format, utilizing only:
  • linear.x (positive: forward movement, negative: backward movement)
  • angular.z (positive: left turn, negative: right turn)

Raw Message Definition

Accepts an array of six f64's

  • six f64 array [x, y, z, rx, ry, rz] only used x, rz

see https://docs.ros.org/en/noetic/api/geometry_msgs/html/msg/Twist.html

Environment

Adds an environment variable SERIAL_PORT to specify the serial port for the car device, with /dev/ttyUSB0 as the default value
