SEA:ME / DES_PiRacer-Assembly

1. Install Ubuntu 22.04 Server on Raspberry Pi (Using Raspberry Pi Imager)

1. Download and start Raspberry Pi Imager from here.

2. Choose OS: "SCL or GUI (Raspbian 64/32 bits)"

3. Select USB Driver.

4. Go to Settings (Advanced Option).

   • Enable SSH and set User_Name, Password.

   • Configure Wireless Lan.

5. Press the Save Button.

6. Press the Write Button.

7. Insert the USB Driver into Raspberry Pi to start installing Ubuntu.

2. Follow the Hardware (H/W) Assembly Manual

Follow the PiRacer Assembly Manual.

3. Follow the Software (S/W) Guide

Follow the PiRacer-py guide.

1. Run the following commands to add the Raspberry Pi repository and update the system:

   sudo -s
   echo "deb http://archive.raspberrypi.org/debian/ buster main" >> /etc/apt/sources.list
   apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv-keys 7FA3303E
   apt update
   exit

2. Install the required libraries and tools:

   sudo apt update
   sudo apt install \
       gcc \
       v4l-utils \ 
       i2c-tools \ 
       raspi-config \ 
       python3-dev \
       python3-setuptools \ 
       python3-venv \
       libopencv-dev \
       piracer-py

3. If you choose Ubuntu, mount the boot partition:

   mount /dev/mmcblk0p1 /boot/

4. Enable I2C and Camera using the 'raspi-config' tool:

   • i2c: Interface Options > I2C
   • Camera: Interface Options > Camera

   Afterwards, reboot the Raspberry Pi:

   sudo reboot

5. Install the piracer-py package:

   cd ~
   mkdir piracer_test/
   cd piracer_test/
   python3 -m venv venv
   source venv/bin/activate
   pip install piracer-py

After following these steps, you can try the example code provided in the link.

• basic_example.py: Operating throttle and steering.
• rc_example.py: Check the Controller (Check Connect, Throttle, Steering works correctly)

• camera_grab_example.py: Check the Camera.

4. Simple Explanation about code

1. basic_example.py

   • Test pi-racer operating well
   • Moving Forward - Backward - left -right - sleep

2. camera_grab_example.py

   • Test pi-racer camera working well
   • After working this file, if you get some image and it operates correctly

3. rc_example.py

   • Control the pi-racer using controller

4. shutdown.py

   • Stop movement of pi-racer
