A 3D printed boat robot using Raspberry Pi, Arduino and PVC pipe #PiDay #RaspberryPi @Raspberry_Pi

Wes writes with information on his boat project.

Since my day job involves writing mobile applications, I knew I wanted to have a control system that used an iPad. I’m also the author of an iOS library that facilitates communication between ROS on Linux and iOS using websockets. The app is designed to use modular blocks that display one particular piece of information. In addition to the blocks shown here, there is a GPS block showing location, a navigation block showing waypoints, temperature and data recording. Click the magnifying glass to expand the block to full screen.

It has:
– 3D printed parts from FDM and SLS
– custom designed Arduino Mega shield PCB with SMD components
Adafruit INA219 x2 and BNO055
– Raspberry Pi 2 and Arduino Mega
– It runs Ubuntu and the Robot Operating System
– it is controlled via a custom iPad app I wrote

This is an in progress look at the electronics plate with its relevant components. Clockwise from top left: Cytron 3A dual motor driver, Adafruit BNO055 9-DOF IMU, Arduino Mega 2560 with custom PCB shield, Raspberry Pi 2 running Ubuntu Server, BU353 USB GPS receiver and 2x Adafruit voltage/current sensors (one for each battery). The Arduino accepts the sensor i2c signals and processes the data into ROS messages that are used by the Raspberry Pi.
