After the last assignment, I looked at my classmates’ launchers and realised how overcomplicated and difficult I had made life for myself. However as we know, there is always a silver lining and in this case, it means that this assignment should be right up my street! I am already the queen of overcomplicating everything for myself and so this assignment suited me down to the ground. After all, a Rube Goldberg machine is a chain reaction-type contraption which aims to perform a simple task in an overcomplicated and indirect way. We’re a match made in heaven. …

“Talk is cheap. Show me the code.” ~ Linus Torvalds

I’ve being doing a lot of talking about it these last few blogs but I haven’t really said how I’m going to get this robot around the course now have I? Well, as the creator and lead developer of Linux Kernel says, the only real way to do that is to demonstrate my code and show you!

Love it or hate it, coding is an integral part of being an engineer. You generally won’t get too far without being at least able to read it. In this assignment, we were…

“The strain (deformation) of an elastic object or material is proportional to the stress applied to it”

Above is a law of elasticity discovered by the English scientist Robert Hooke all the way back in 1660 but one which we still use every day and, conveniently, that I have also based my ping pong launcher on!

So once again, welcome back to my blog! Or, if you’ve just stumbled across this post in your quest to make the best DIY Ping-pong Propellor known to man, then welcome! …

Another day, another blog post! Welcome back guys!

As you can probably tell by the title, this blog post is going to take us through any of the little tweaks or changes I made to Eli’s physical set up in order to complete the tasks. You know the suss at this stage, Eli must navigate the obstacle course (without simply using all his pre-programmed code) and then he has to catch some ping pong balls.

“But Aoife, I can’t catch balls or stand up without you :’( “

The Catcher

Obviously first things first here, Eli simply has no way to catch these balls in his current form so of course something had to be…

When my mother first heard the words ‘Obstacle Course’ she was hesitant. When she then heard that I’d need to have it constructed for about two weeks in order to practise she said “No way.”. And to be fair there wasn’t really any 2m x 0.6m area in the house where I could build this thing without it being totally in the way and inevitably tripped over and destroyed anyway. So instead I decided that best way to go about this would be to tape out the outline of the course and make marks where I’d need the inner walls…

The moment has come, Eli has finally arrived! After weeks of waiting it was time to get down to business. The two things on my checklist? Assembling and Testing.


Firstly, Eli arrived in a cute little box and was very well packed up, giving me peace of mind that all the components would be in tip- top working order despite the long journey to Roscommon.

It’s blog post #3 and there is still no sign of Eli. I’d held off on this post in the hope that he would arrive and I would be able to show off my finalised CAD with all his little features but alas my deadline is approaching this weekend and I can’t hold out any longer. It’s a pity but what can you do, there were still bits and pieces I could add to my assembly without physically seeing Eli anyway.

The majority of the work was making slight adjustments to dimensions, materials etc that I hadn’t rectified first time…

Unfortunately due to Brexit and some.. shall we say sub-standard customer service, Eli’s arrival has been delayed :( So, to keep myself occupied in the meantime, I have began modelling his main features through the much-loved computer-aided-design package, SolidWorks! Of course this has proved difficult at times, as at the moment, I’m making approximate estimations of dimensions based on online pictures (such as the following) but bear with me as I take you through the process so far!

Also, just a little side note before we get cracking; if you’ve found yourself working remotely and using a SolidWorks on a…

Hello, world! and welcome to my blog.

First things first, get to know me! I’m in my third year of Engineering with Management; a unique course offered in Trinity College Dublin. One of 7 girls amidst 21 boys, blessed are thou amongst men as despite the unequal numbers there is a great dynamic in the group. We all motivate, inspire, encourage and help each other out, something which I think is especially important these days. …
