Customization Plan

The Goal


AND adding computer vision capability to the robot.


Arduino Shields

It's easy to add remote connectivity to robot using Wifi/Bluetooth shields for Arduino. But that doesn't help with the limited computing power of Arduino. I don't want to build a purely remote-controlled robot with it's brain sitting in an iPhone or Android. I have a plan to plugin a camera for computer vision, Arduino can't help on this.

Raspberry Pi

It sounds a good option. Raspberry Pi 2 or 3 is powerful enough to run Linux programs on the robot. And it's cheap, compared to Arduino shields, only a few bucks more.

The challenge is how to plug Raspberry Pi to Zumo. Google didn't tell me much useful information (I need details!). Some projects make me fell confident down to this road:


Most of Raspberry Pi on Zumo projects connect Pi and Zumo using either:

  • USB cable (may not work with Zumo for Arduino)
  • Arduberry or similar solutions

And the Pi is powered separately. You can find the funny pictures showing little Zumo carrying big USB powerpack for Raspberry Pi.

I don't like a separate power supply. I want to use the single power source from the batteries of the built-in Zumo chassis. I'm not quite sure 4 AA NiMH batteries will be enough. I'm willing to find out.

Besides, I want to assemble these pieces of PCBs, camera supporting kit and camera in a clean way (without too many wires flying around). It will make my life much easier in future to build a shell for it.

Detailed Plan

This is the plan to build zpi1:
