Serving Raspberry Pi #7: Meet Berry Bot

Wednesday, October 26th, 2016

The November 2016 issue of Servo Magazine is out – and I got the cover!!!


It this article I started building Berry – a RoboPi + Raspberry Pi 3 based 4WD robot.

As you can see, Berry has a red 4WD chassis, Patriot USB power bank, RoboPi, Raspberry Pi 3, Sharp IR distance sensor, and a 9g micro servo.

What you can’t see is that Berry also has an L298N motor driver board, HMC5883L used as a compass, and a 4xAA cell battery pack to power the motors.

This article shows how to connect the parts, and presents some simple Python code for the compass.

For the full skinny, read Servo :)

Unpaid plug: if you are into bots, I highly recommend getting a Servo digital edition subscription – which also lets you read all back issues (including my past articles <grin>)

BTW, sorry about the lack of posts & articles, other work kept me busy.

  • I’ve found a freight forwarder to work with, which allows me to offer cheaper shipping to the US – with tracking!
  • Would you believe it is cheaper for me to ship to the US than to Canada??? Weird, eh?
  • I also have somewhat better rates to the UK and UE, but I am still trying improve shipping there
