This blog will detail the various adjustments I made to the robot to help it navigate the obstacle course and effectively catch the balls. It follows on from a few adjustments I made to the Robot Stabiliser in the Assembly and Testing Blog so make sure to check that out first!

For the most part, the robot could navigate the obstacle course extremely well. However, various design adjustments had to be made in order to add the bucket. I’d initially written parts of this into other blogs so there may be overlap once again. …

While I have a specific blog on the obstacle course that encompasses everything from navigating the course and firing the ping pong balls that you can find here. However, we’ve been tasked with writing a blog that covers its construction. I’ve explained a bit in the main Obstacle Course blog but here’s a quick refresher. There’s a bit of overlap but you’ll find the majority of the technical building aspects here.

I drew up a really simple CAD design to help visualise this course a lot more. …

This blog will cover the layout of the obstacle course and the various processes I went through in order to successfully navigate the course using the Elegoo Robot. The robot should navigate the course and then collect as many ping pong balls as possible being launched from the Ping Pong Launcher. Here are the draft rules as of now:

** While most of my blogs are dated and follow a chronological order, given the nature of this blog that involves the programming and launching aspects, I’ve split the blog into two sections rather than regular dates, chopping and…

The robot has arrived! I collected it from College yesterday (25th March) and started assembling it this evening. It was great to finally get my hands on the Robot.

Assembly, as predicted, was extremely simple and intuitive. There were no issues regarding screws or parts missing. Everything went extremely smoothly and I followed the process laid out in the manual to the letter. Ironically, having the CAD model done in advance of receiving the actual robot made assembly a dream. In-depth knowledge of the components made this a very simple process. …

Well, I thought it was time to start simultaneously get cracking on the Ping-Pong launcher at the same time as the Rube Goldberg Machine. I was hoping to focus more on it when my Robot finally arrived but it’s not looking too promising. Anyway, on we go. The Ping-Pong Launcher (PPL) is part of the obstacle course which I’ll discuss in further blogs. For the moment here are the requirements;

I must build a device that harnesses potential energy and launches a PP over a 500ml water bottle into a cup the Elegoo Robot Supports.

This blog will detail the intricacies of my CAD modelling of the Elegoo Robot. As stated in my general blog, I’ve decided to wait until the Elegoo arrives to construct it via SolidWorks. I understand a lot of my classmates have started and rendered their models, but I think I’d utilise my time best working on the Rube Goldberg Machine and the Ping Pong Launcher. I’ll update this blog as soon as it arrives!

Components

As previously posted on the general blog, here’s the list of components. I’ll be developing each part separately then assembling it using CAD software…

Introduction

This blog will document the design and construction of the Rube Goldberg Machine. As mentioned in my introduction blog, I’ve been tasked with constructing a Rube Goldberg Machine where the robot plays a starring role.

A Rube Goldberg Machine is a chain reaction-type machine or contraption intentionally designed to perform a simple task in an indirect and overly complicated way. Here’s a fantastic example: Page Turner. It takes 2 minutes and multiple unnecessary processes to simply turn a page.

I drew up some draft flow diagrams to help illustrate this concept with a bit more clarity.

To get started on this blog I thought I’d give a quick breakdown of what’s going on. Despite engineering being a practical ‘ hands-on’ degree, recent unmentionable events have meant that college continues to be online for the remainder of the semester. This blog is the result of a contingency plan to assess us for Semester 2.

Alas, fear not, just because it’s for college doesn’t mean it can’t be fun! …
