CS 453 Lab 5: Docking

This lab serves as an introduction to ROS2 using the Create3 from iRobot. The Create3 is a mobile robot that can be controlled using ROS2. The Create3 has a docking station that it can autonomously dock with. This lab will focus on using the Create3 to dock with the docking station.

Steps:

1. Undock
2. Drive 1m
3. Turn randomly
4. Drive 0.5m
5. Dock without the Dock action

Additional Requirements:

• Add chirp tones between transitions. For Example, before you drive, play a tone to signify you’re driving.

• Different tones between steps might be a helpful debugging tool!

• Fully docked is: /dock_status.is_docked = True

Running the Code

Requirements

• ROS2 and the Create3 ROS2 packages must be installed. See the Create3 ROS2 Setup for guidance.

• This Repo

Build

Use colcon to build the packages

$ colcon build

Run

1. source the ROS2 environment:

$ source install/setup.bash

2. Spin up the dockStatus node:

$ ros2 run dockStatus dockStatus

3. Spin up the dock node:

$ ros2 run dock dock
