Kyosho (#40661) Wave Master Box

More than a few years ago, I bought myself a Remote Control boat, a Kyosho Wave Master:

The WaveMaster is a semi scale model of an F-1 tunnel hull racing boat. Tunnel hulls work by trapping a cushion of air between the hull and water to reduce friction which allows the boat to travel even faster. The WaveMaster’s hull and upper decking is made of lightweight, tough and glossy ABS plastic, and is largely pre-assembled to help reduce build time. Power is supplied by Kyosho’s new design outboard motor. This compact power plant utilizes an 550 class motor and drives the propeller via a wire type drive shaft.

I mostly sailed/controlled it of a Friday evening at Bowmoor Lake while out with First Swindon Sea Scouts, for the last few years it has mostly been sat in my parents loft, however with wanting a test bed for K9 and ROV stuff it seemed like a good development platform for using to test software and hardware. especially as being a boat, I can use it while at home.

I came across a RC Car Controller thing for the Arduino / Raspberry Pi on Github “rc-car-controller” – Operate a RC car over the internet via node.js using socket.io and johnny-five, using an Arduino connected via USB, however I have a RPi-UNO-HAT – Raspberry Pi Arduino Extension from Watterott electronics (github link) to play with.

I have been unable to get the rc-car-controller software to work, however it has given me a starting point to play with.

Getting the Raspberry Pi Ready

1. Grab the Latest Rasbian Image from http://downloads.raspberrypi.org/raspbian_latest
2. Burn the image to an SD card
3. Change the Host name by editing these two files /etc/hosts and /etc/hostname.
4. Update/upgrade OS, then restart:

   sudo apt-get update
   sudo apt-get upgrade
   sudo rpi-update
   sudo ldconfig
   sudo shutdown -r now

5. Then use rpi-config as normal to expand the file system and enable the camera

   sudo raspi-config

6. There are some additional things to install once the storage has been expanded:

   sudo apt-get install minicom g++ curl pkg-config libv4l-dev libjpeg-dev build-essential libssl-dev cmake git-core build-essential libjpeg8-dev imagemagick subversion netatalk mosh arduino <code class="bash plain">tightvncserver</code>

7. Set up the UART on the GPIO pins (instructions here).
8. To make using the RPi-UNO-HAT it is worth now installing and setting up VNC, and then setting up the Arduino IDE:

   wget //raw.github.com/watterott/RPi-UNO-HAT/master/docu/autoreset
   wget //raw.github.com/watterott/RPi-UNO-HAT/master/docu/avrdude-autoreset
   chmod +x autoreset
   chmod +x avrdude-autoreset
   sudo mv autoreset /usr/bin
   sudo mv avrdude-autoreset /usr/bin
   sudo mv /usr/bin/avrdude /usr/bin/avrdude-original
   sudo ln -s /usr/bin/avrdude-autoreset /usr/bin/avrdude

   Test that the above has worked by running

   sudo avrdude -c arduino -p m328p -P /dev/ttyAMA0 -b 57600 -v

9. Link ttyAMA with a serial port that the Arduino IDE can see by creating the file

   sudo nano /etc/udev/rules.d/80-arduinopi.rules

   and adding

   KERNEL=="ttyAMA0", SYMLINK+="ttyS0",GROUP="dialout",MODE:=0666

   to it, then rebooting.

10. 

    Raspberry Pi Arduino with RPi-UNO-HAT

    Dial into the Raspberry Pi via VNC, you will need to run vncserver :1 to start the server (will work out why at some point), Connect RPi-UNO-HAT, and open the Arduino IDE.
    Open the Firmata sketch via the menu:

    • File > Examples > Firmata > StandardFirmata
    • Select your Arduino board type (Arduino Uno) via Tools > Board
    • Select the port for your board via Tools > Serial Port > (/dev/ttyS0)
    • Upload the program by selecting File > Upload

    Close the VNC connection.

11. Install node modules:

    npm install socket.io express johnny-five body-parser

12. Install python libraries:

    sudo apt-get install libopencv-dev python-pip python-opencv python-dev python-picamera

I will be working on part two soon 🙂
