Pi Wars

Helen: This December will see a Cambridge Raspberry Jam with a difference; we’re giving you all plenty of notice, so that you have time to prepare. We’ll let organisers Michael Horne and Tim Richardson tell you all about it. On 6th December this year, the Cambridge Raspberry Jam (CamJam) will play host to the first... Continue reading

An image-processing robot for RoboCup Junior

Helen: Today we’re delighted to have a guest post from 17-year-old student Arne Baeyens, aka Robotanicus, who has form in designing prize-winning robots. His latest, designed for the line-following challenge of a local competition, is rather impressive. Over to Arne… Two months ago, the 24th of May, I participated in the RoboCup Junior competition Flanders,... Continue reading

DoodleBorg: a three-horsepower robot tank

PiBorg are an organisation making add-on boards for your Raspberry Pi. Recently they produced the biggest and most powerful Pi robot we’ve seen so far, using one (six, actually) of their motor boards: the resulting DoodleBorg is a three-horsepower beast powered by motorcycle starter motors. To all intents and purposes, it’s a small tank. With... Continue reading

Ziphius, the Pi-powered aquatic drone, now on Kickstarter

We first came across Ziphius when Rob Bishop went to do some talks and workshops in Portugal. Ziphius is a Pi-powered aquatic drone, equipped with cameras, who displays autonomous behaviour and can also be controlled from your phone or tablet. I say “who” rather than “which” because despite the lack of a face, arms or... Continue reading

Pi-powered cat feeder

Mooncake, the Official Raspberry Pi Cat, is fed biscuits twice a day by an off-the-shelf cat-feeding robo-hopper that we bought before Raspberry Pi was a reality. (She also gets that horrible-smelling cat food in gravy from a packet, served up by real live humans.) I’ve just found out what to replace the robot with when... Continue reading


This is brilliant. Livebots is a project which allows you to control a robot (powered by the Pi, of course) over the internet. Follow the link, or watch this rather excellent video to see what’s going on. You’ll be using buttons in the browser to send Python instructions to the robots via their serial ports....

Guest blog #1: Repurposing a Roomba by Ben J

Clive: The future has been so disappointing. We were promised force fields; teleporters; and androgynous, android manservants. Instead we got cagoules, budget airlines and robovacs. And what do you do with a robovac when it reaches the end of its useful life? You stick a Raspberry Pi on it and make it into a proper... Continue reading

Thursday grab bag

Heatermeter Want to control the temperature of your barbecue, smoker, firepit or clambake over a web interface? Here’s the Raspberry Pi-powered HeaterMeter. Bryan Mayland says: HeaterMeter for RaspberryPi joins an Arduino / AVR ATmega328 microcontroller with OpenWrt running on a RaspberryPi $35 wonder-computer for the purpose of providing oven-like control of a charcoal BBQ grill via web...

The Dark Pi Rises

I’m getting a real kick out of some of the fan movies that have been appearing on YouTube. Algorhythmic from Aon² has been featured here before with his robot arm. Now he’s got a night-vision robot that wants to be Christian Bale. Is there anything you guys can’t do?... Continue reading

Robot: destroy!

Algorhythmic from Aon² has been working on speech recognition with his Raspberry Pi, and has a very nice video demo of a voice-controlled robot he’s been building, with full instructions on how to get something similar working yourself. (Edit to add, 12 Jul: the arm itself is available in the UK from Maplin – it’s... Continue reading
