After weeks of build up, the Rube Goldberg Machine has finally been completed. Shown below is the course layout and the finished run is attached at the end of this post.
The course beings with my Arduino powered robot moving a piece of cardboard into a book. This creates a domino effect which tumbles around a corner, landing on a trip wire. This wire is connected across the room to a weighted basket on a height. Once the wire is tripped, the basket falls to the ground, pulling on another string that is linked to a swivel…
Welcome to the final blog post in this Design II module.
In this post I would like to tie up a few loose ends and comment on a few aspects of this project. But first, what you have all been waiting for, the successful course navigation and ping pong ball catch:
I would like to note that although I successfully managed to get the ball in to the basket first time in this video, this did not happen every single try. I was shooting the launcher from approximately 120cm away from the Robot and I had a success…
In this post I will be showing the Robot navigating the course with its cardboard basket attached.
In order to complete the final submission I must successfully record the robot navigating the course and collecting the pingpong ball before it returns back to the starting point.
The final video will be uploaded later this evening.
Welcome back Everyone!
Today is the final day of my Robot Project and I would like to share my Ping Pong Ball Launcher design.
On the left is my final design for the ball launcher. It is relatively accurate and can successfully launch the pingpong balls into the basket I have attached to the Robot. The zip tie connecting the bungee string and the bull clip builds up the potential energy and once the clip is opened it is converted to kinetic energy, launching the ball up to 120cm into the basket.

Stay tuned for more,
On a slightly un-Robot-related note, I would like to briefly talk about another part of my Design II module this semester. We have been tasked with designing a Rube Goldberg Machine. If you are unfamiliar with Rube Goldberg, he was a famous American Cartoonist. However, a Rube Goldberg Machine is a machine that performs a task as a result of a chain reaction. For example, in the image above, once the man lifts his spoon to have some soup, the napkin is triggered to wipe his face. These machines can range in complexity, as well as with what type of final task is performed.
As part of the brief my Rube Goldberg Machine must involve my robot. I am excited to share my machine once my plans and designs come together.
In this post, I will be sharing the set up process of my obstacle course. There have been a few small changes in the a, b and c dimensions in the schematic shown, but, the main layout still stays the same.
I have chosen to replicate this course using cardboard boxes. It was necessary to put down some cardboard in order for the robots wheels to move smoothly as I have a carpeted floor.
As I am nearing the end of my 2nd semester of 3rd year, the dead lines have been coming thick and fast so my progress with the robot has been slower than I had hoped. As per my last post, the robot is up and running and I am able to control it using the Bluetooth from my phone to control its navigation. The next step is to unpack and master the Arduino board’s code components.
The upcoming obstacle course challenge requires the robot to move through an obstacle course running on the instructions that I have programmed…
I am very excited to share my progress this week with you all! After a lot of waiting, the Robot Kits have finally arrived. I began the assembly process yesterday morning and before I knew it, I had a fully functioning self-balancing robot roaming around my desk! The assembly process was very straight forward, and the instructions were very clear. However, in true engineer fashion, I tried to assemble it without looking at the instructions (with no mistakes I must add).
Hello Everyone !
Now that you have all seen ELIE the Robot, the next task in my Engineering Design II module is to design a stabilising mechanism to allow the robot to navigate a small obstacle course without replying on its active balancing capabilities the whole time. It is suggested that the mechanical balancing mechanism is attached to the front of ELIE, connecting to the clear plastic L shaped bracket.
I am currently in the process of perfecting the design of the additional stabiliser on Solidworks. Shown are rough plans of what the attachment drawn up on Solidworks. I have…
