My view on… Erasmus @ Group T

Note: This was the situation in early 2012, since then Group T has improved the whole process a bit.

As the minister of Education is aiming to get at least 1/4 students out on an Erasmus experience, let’s take a closer look at how things are handled at Group T. From my point of view that is. I’m not going to discuss coming to Group T as a non-Belgian student, just the other way around, as a Group T Electronics-ICT student going abroad.

As noted on the Group T website there are several semesters you can choose from, being in my 3rd bachelor year and having a friend who was considering it I thought it’d be a cool experience to have as well. Judging from the blog and photos of my stepbrother, it sure is. Anyway, we checked out the listed partner universities, too bad the information is insufficient and rarely updated.

We started out by selecting some universities we thought were pretty good, such as the ones in Finland and the UK. Sadly the Finnish one almost had no English courses and attending classes taught in Finnish wasn’t going to work. Rejoice when we found a lot of matching courses in England! When we decided to go ask the Erasmus coordinator at Group T, she informed us the agreement was only for the chemistry department (why isn’t this information on the website?). Onto Denmark, no luck either, after pushing to call the university it appears they do not accept any more Erasmus students. The search continued..

Matching courses is quite a bit of work, we had a couple of universities that would do, however none of them seemed to be eager to accept Group T Erasmus folks. At the moment we asked to contact the university my stepbrother is at, though enthusiastic, the coordinator didn’t call right away, which I think would give an answer a lot faster than ‘waiting a week for them to respond to my email’.

I think it’s kinda unfortunate Group T profiles itself as an ‘International University College’ though going on Erasmus as a Belgian student (at least when you’re in the Electronics department) is a huge struggle to even get one university you can go to. We’ve been trying for over a month now and without any luck. It seems most of the partners do not have matching courses for the Electronics master.

First of all they should put a LOT more work into the Erasmus section of the website, add more useful, correct, accurate and important information. There are just a couple of Electronics students that applied, a couple being less than five! I’m starting to think quite a lot of people just give up after spending hours on trying to get a program together which is shot down soon after.

That being said, the professors are very helpful on the other hand. The Electronics department director tried his best to help us and some of the professors we asked were prepared to take a look at courses of other universities to see if they matched with theirs.

In the end I think Group T still has a long way to go if it truly wants to be ‘International’, at least for its native students. Promotion for this is rarely seen, only after we asked about it they put a small news post on the Group T site linking to the (outdated) Erasmus page.

I’d love to hear other Group T students and their experience with applying for an Erasmus semester as well as the story of people who returned after being away for a semester. I’m sure if more people would blog about it, or even talk about it, more students would be interested and hopefully more effort would be put into the whole program. But there are no testimonies to be found (do link me to them if you come across them though).

We’ve been waiting for about a week for a reply from Sweden but no luck yet, it seems chances for a semester abroad are slimming by every passing day.

Update July 2012: Managed to get accepted into Politecnico di Torino, check the Erasmus tab at the top of the site to see more information.

Maestro MuzaBot

Every year at GroupT there are one or two so called Engineering Experience projects. These projects usually involve a team consisting of around five people from the same year. This semester it was time for ‘Engineering Experience III’.

I started off mailing people even before the start of the semester because I wanted a good, functional team to work with. My dreamteam was a group of only EA (electronics) students, but it was not possible partly because I didn’t know enough people who are going to do EA starting next semester besides a couple of friends.
After a few requests and another handful of e-mails the composition of our team was finalized. Diversity  all around with two biochemical, one electromechanical and two electr(on)ical engineering students.

The objective of this project was to create a machine or robot that could be controlled by a computer using LabVIEW, Computer Based Control. Joy for the EA folks, a little less happiness at the other quadrants of the GroupT spiral. Nonetheless, no one has died from this course yet so there we were, trying to come up with a cool and realistic idea.

After an hour of brainstorming or so we had a couple ideas written down on the blackboard. Some were too hard to even consider them, others were too silly or too easy. Being a musical person myself I proposed a robot that could play some instrument, just like The Trons. Eventually everyone agreed and we quickly decided to use a metallophone  and some homemade drumming construction.

After over hundred hours (per person) of working on the software, construction and electronic circuits the result is pretty satisfactory. It could’ve been a better had we not neglected deadlines a couple of times (not gonna happen again, ever!) as we had to rush some things in the end to make it ready for the presentation.

The construction of the modules consist of Fischertechnik, LEGO and LEGO Technic blocks. Since those don’t always fit flush together we had to glue some things to make it work. The big parts are

The Read Module

Read Construction

This part of the robot can read homemade music sheets which it translates to numeric values so LabVIEW knows how to handle it. This is achieved by using a set of IR-LEDs and IR-receivers (photo-transistors) . You feed the construction (not shown) a music sheet, it’ll detect it and start pulling it in. Once the sheet has gone through the reading part the motor automatically stops.

The Metallophone Construction

Metallophone

 

Next up is one of the two modules who take care of reproducing the music. This part contains 2 motors, four musical tones (C, D, E and F) and a couple of switches. Based on what is in the arrays the hammer will first move on the x-axis to the correct position and then move in an arc-like motion to ‘slam’ on the metallic plates. A bonus thing is, both this and the drum module are ‘in sync’ as they will hit their respective target at the same time.

The Drum Module

Drum

The  drum can either hit a metal can or a plastic cup. This is the simplest construction of the robot as it only uses one motor and two switches put in parallel. As mentioned before, the hitting takes place as soon as the x-axis of the metallophone signals it’s ready to start the “hit” sequence.

The PCB and DAQ

PCB

 

 

 

The missing link between the modules and LabVIEW on our computer is the actual PCB which every electronic component is connected with. This specially designed for this course circuit board contains some basic things such as 9V and 5V voltage sources as well as other in and out gates. Another interesting component is the H-bridge so we could easily make the motors run in both directions.

Aside from this PCB, we also had a National instruments DAQ card, the 6008-USB. This DAQ-card was hooked up with a computer which runs LabVIEW. It’s relatively cheap but it’s got more features than we could’ve asked for.

GUI

Actually using and controlling the robot can be done through a GUI I made. Here you can see what is going on (yellow part), how many beats are ready to be played and how many have already been played (orange) and the virtual representation of what is being played (green).
The blue and red parts are the areas where you can either save/load music or enter your own tunes. This makes a total of three ways to add music information into the robot.

This project was a lot of fun in my opinion, and I’ve learnt a lot by designing the program in LabVIEW and helping with the construction of the different modules. Last but not least, feel free to check out the following video of the machine in action (sorry for the crappy audio/video quality!)
