PiBoe = Pi + RoboPi + Boe-Bot

Upgrading the Parallax Boe-Bot with RoboPi + Raspberry Pi

Back in 2011, I upgraded a standard Parallax BOE-Bot with my RoboProp propeller based robot controller.. I wrote a two part article for Servo magazine about the upgrade, and it was published in September 2011 (I got the cover!) and Octoboer 2011.

Fast forward to 2014, and once I designed my RoboPi controller for the incredibly popular Raspberry Pi, I could not resist trying to control a Boe-Bot chassis with a combination of RoboPi and a Raspberry Pi.

The only problem with my first attempt is that it was way too tall!

PiBoe previously consists of:

  • Deck 4: RoboPi – Main engineering :-)
  • Deck 3: Bridge – Raspberry Pi Model A (or B), communications (WiFi)
  • Deck 2: EZasPi (B), prototyping, P5 Pi I/O
  • Deck 1: Proto 300, prototyping, sensors
  • Main deck: USB Battery Pack, sensors
  • Engineering deck:: Servos, battery pack for servos

The USB battery pack, plus the AA pack under the aluminum deck, should provide a low enough center of gravity that PiBOE won’t tip over.

Previously I wrote:

Right now I am considering eliminating Deck 2 (EZasPi (B)) in order to reduce PiBoe’s height. I just need to provide a female header to match P5 on the Pi, and drill two mounting holes.

I can’t eliminate the Proto 300 deck, as I need the space below it for the Pi’s battery pack.

Well, I have done just what I said I would do, and shortened PiBoe:

  • Deck 3: RoboPi – Main engineering :-)
  • Deck 2: Bridge – Raspberry Pi Model A (or B), communications (WiFi)
  • Deck 1: Sintra deck
  • Main deck: USB Battery Pack, sensors
  • Engineering deck:: Servos, battery pack for servos

Now that is much better! PiBoe looks much better proportioned.

Let’s take a look from the back:

I’ll keep this page updated with PiBoe’s progress!

Coming next:

  • Ultrasonic Range sensor
  • IR range sensor
  • compass
  • Pi Camera
