La section Robotique

Hello, we are the robotics section of the CMC. Our aim is to be the go-to place for everyone who is interested in robots, electronics, hacking and general cool projects in, around and outside CERN. It should be stressed that although we're called the Robotics Section, we also have non-robotic adventures and projects.

We currently have our regular meeting on Wednesdays from 6pm in the Micro Club hut please come along to find about us in person.

If you can't make it in person check out our Github organisation here.

Current Project:

We are currently building an InMoov humanoid robot. Whilst we can more or less print modest objects with our 3D printer, we are using the Reprap Pro in Ideasquare for this, with their agreement. It's a complicated project that will require 3-5 people for a few months (maybe even a year - we've built one arm in 5 months so far) to complete. When it's finished it will be installed in Ideasquare to welcome visitors, and we can borrow it for any applications that present themselves. If you are interested in this, or have ideas for another project please contact James Devine or come along to our Wednesday meetings in Ideasquare.

What it looks like today:

InMoov Right Hand























What it will look like on completion:


Past project:

Decoding live satellite weather images, during the month of September. We're using an RTL SDR dongle and various bits of software to accomplish this, together with a fantastic antenna constructed by Ralf and Sebastien. Here are links to some of the resouces we've been using - images will be posted when we succeed!

Raspberry Pi Robot Challenge

On Wednesday 17th June three intrepid teams entered the IdeaSquare space to compete in the first Raspberry Pi Robot Challenge. Each team was given a Lego NXT robot chassis, a marker pen and a Raspberry Pi with which they had to solve two challenges, a drawing competition and a maze. Teams were able to connect to their robots via WiFi and programme the robot's actions using a web interface called Raspbuggy written specially for the event by Brice Copy. All teams were able to successfully use the web interface, which the Robotics Section plans to re-use for future events using the Lego NXT Robots and other platforms (including dedicated Raspberry Pi buggies and modified RC cars). All teams were successful in attempting the drawing challenge with varying degrees of success, however none were able to make it through the Maze within the time limits. The competition was great fun for all involved (even the organisers) and will be repeated in a similar form later this year.

Source code for the web interface is available from our GitHub account.

Robotics Section - Latest developments

What have the robotics section been up to recently? Here are some answers. Mostly - related to car hacking and playing (carefully) with lasers.


We bought some laser galvanometers from aliexpress for about 120 USD/each, without lasers. They run on 230V AC and have an ILDA interface + an SD card slot. 

It also has R-G-B TTL outputs for the control of 3 lasers. 

Here's a video of it in action. 

In terms of what we're doing - stage 1 will be to find a suitable housing to put it inside (from a skip!), possibly connect it to batteries instead of the mains. Stage 2 will be to make a direct computer interface, either via Raspberry Pi or Arduino. At the moment the ILDA interface is analogue, so an ADC hat/shield would be required - this is rather circumlocutory since the interface re-converts this to a digital signal, and then back to an analogue again to drive the galvos. Stage 3 will be to project something cool onto something big. 


Car Hacking

We've been playing with OBDII interfaces and helping out the folks at with the development of their open source, open hardware, community car sharing scheme. James has designed a Pi-Hat which integrates all the functionality required for the hardware module (just add a Pi + 3G dongle), the design is available here on Github.

Laser Projector Project

We are starting a new short project as a break from the InMoov assembly. We will be building several laser projectors, the quantity will depend upon the number of interested people. The idea will be that we bulk buy the equipment from a supplier and assemble/hack it together ourselves using our ingenuity on Wednesday evenings.

Coding Pi Science days 2016

2016-11-16 (journée entière)

On 7th and 8th October 2016, the club organised "Coding Pi Science Days" (Journées Raspberry Pi), an educational event to initiate children and students under 18 to programming.

Working together with long-term Pi supporter Alan McCullagh, the club invited three teams to prepare scientific kits to build and program with attendees. 

To motivate the teams and the other attendees, a series of talks on Friday evening were given at the CERN Council Chamber; these included a general introduction to the CERN Micro Club and the European Code Week, as well as a motivational talk on why computer programming is so important for scientific research. Each team then gave an overview of their project, in preparation for the workshop the next day. On Saturday morning, the teams, volunteers, children, parents, and teachers started to build a muon detector (Muon Hunter), a robotic arm (Poppy Ergo Jr.), or a programmable WiFi car (GianoPi).

The idea was to build a kit together with the team leaders and other volunteers, and then take the kit home to program it. 

The Muon Hunter was designed by Mihaly Vadai, in collaboration with the CERN Micro Club. The kit includes two Geiger-Müller tubes to detect ionising radiation, a circuit board that produces the 400 volts needed to bias the tubes and read the signals, and an ARM microcontroller to form the coincidence between the two tubes. The circuit board can be directly connected to a Raspberry Pi to read out the signals and produce plots of the data.

Poppy Ergo Jr. was invented by the Flowers team at Inria Bordeaux, and presented by Stephanie Noirpoudre and Theo Segonds. Their projects are designed to encourage children to learn about computer programming through interacting with robots. The kit includes 3D-printed parts and several servo motors controlled by a Raspberry Pi mounted in the base of the robot. A Camera Module can be used to check the colour of objects, and forms part of their Snap programming examples. 


GianoPi was designed by Stefania Saladino and the CERN Micro Club. It consist of four DC motors, multi-directional wheels, an ultrasonic sensor, a Pi Zero, a camera, a DC control HAT from Adafruit, a WiFi adapter, a battery pack, and some electronics to allow the kit to be easily turned on or off. Brice Copy created the software to interface with the GianoPi using Raspbuggy, which is a Blocky application.

Similar to the Poppy Ergo Jr., the GianoPi is controlled over a network connection, allowing the robot to be remotely accessed. It was an engaging weekend of soldering, building, and programming; Hopefully, these kits will encourage even more exciting projects in the future.

 The event was a great success, no thanks to the efforts and continued support of the CMC club committee and all event speakers !


Here is a very nice Ergo Jr assembly video prepared by event attendee young Guillame Delille :
