During the YRS Festival of Code 2015, “SubjectRefresh” and I created a revision app called Refresh. It’s built using Node.js and works by scraping the exam board website (currently only CIE) for the PDF for the syllabus the user has requested. The PDF is then converted to HTML using a PDF to HTML converter and is then shunted through Node’s Cheerio library. We then find out where the relevant information in the HTML is and send that off to TextRazor.

I admit it, I’ve started writing all of my new projects in Node.js. Why? Because most of them are lightweight and I want them to be real time.

We have also shown that it can be adaptable to any circumstance and any user or their medium of control.

The first prototypes we put together used an Arduino, and it was with these first prototypes that we had many problems with the motors.

Despite the fact that it didn’t make it into the final model, it was a valuable tool for prototyping, developing and testing our ideas before applying them to the robot.
