ESP32 Maqueen Battle Bots

This project consists of MicroROS running on an ESP32 and ROS2 running on a Host computer.

The ESP32 based Turtle bot consists of off the shelf parts

and the MBits ESP32 replacement for a MicroBit boaord. https://www.elecrow.com/mbits.html

The Development Environment

The development enviroment will consist of 2 docker containers. One Docker container will run the Host ROS2 system Anther Docker container will act as the Build/Debug platform for the ESP32 code / MicroROS.

Create the Docker container for Esp32 Maqueen Turtlebot

Clone this repository on to your host system From the top level directory, run the following commands.

Build the Docker Image

• docker build -t mros-esp32-idf docker/microros-espidf/

Launch the container

• sh docker/microros-espidf/startNode.sh

Compile the ESP32 code from within the container

Execute a bash shell to attach to the container then execute the following commands

• cd /opt/microros/bots/maqueen-esp32

• source /opt/esp/idf/export.sh

• idf.py fullclean

• idf.py reconfigure

• idf.py build

Upload the code to the ESP32 board

Connect the MBits board to your host computer and using the USB connection and run the following commands

• idf.py flash

Once the code is uploaded to the board, you can observe basic logging using the built in Serial Monitor.

• idf.py monitor

To Create the Docker that will run the Host System

From the top level directory execute

• docker build -t rosimg ./docker/ros/

• sh docker/ros/startNodeUnix.sh rosn10

To compile and run the MicroROS Agent code

Execute the following commands

• cd /opt/ros/ros_ws/agent

• source /opt/ros/galactic/local_setup.bash

• source install/local_setup.bash

• rosdep init

• rosdep update

• rosdep install –from-paths src –ignore-src -y

• colcon build –cmake-clean-cache –cmake-clean-first –cmake-force-configure

To run the MicroROS Agent

Execute the following commands

• source install/local_setup.bash

• ros2 run micro_ros_agent micro_ros_agent udp4 –port 8888
