An assignment for IT requires students to create a programming project related to the school in some way. We had the option to work on code for the robot, which Ryan and I decided to do. I am working on the front end control interface for the robot. I have documented my progress, which is...Read More
I worked on a new power delivery system for the Raspberry Pi. Originally I designed this schematic: However I later found a simpler PCB that had all the functionality required. This is the device we will use: https://www.adafruit.com/products/1944 This is the PowerBoost 500 Charger. With a built-in battery charger circuit, it can keep the Pi...Read More
After a long hiatus, the team return to the project. Today, we set up a test print of our new modular chassis, which will take at least 10-12 hours. I made a few changes were made to the modular clip to increase the strength, however after some discussion we have now moved to a different...Read More
After taking home a 3D printer over the holidays, Matthew and I are working on designing the new modular chassis. Below is a modular locking “clip” mechanism I designed. It looks promising and is likely we will be using something similar to this on the final robot.Read More
Paper jam? Not quite. Although it does involve printers. 3D printers. Our new modular locking system is complete but has not been printed, and therefore has not been tested, and therefore has not been incorporated into the robot chassis. We have three 3D printers at our school, however the main one that we have used...Read More
Our team 3D design expert Matthew designed the new chassis for the robot, and then after a discussion with myself and Mr Elias, began to create a locking mechanism that would allow for a fully modular robot. One of the prototypes pictured above is a double-locking system with two stages of security. The first is...Read More
The team met for the first time since Robocup, but with OpenCV installed and working, we began to make some actual progress. Before we start describing that, it’s important to note that we now have an easy way to transfer files to and from the Pi without the need for a USB mass storage device....Read More
Robocup Regionals! I took the robot home overnight to install the necessary packages such as NumPy, SciPy, Matplotlib, OpenCV and ffmpeg. On the day, we got off to a great start, being super prepared with a fully functioning robot – we wish. There’s still a whole bunch of stuff we needed to do – and...Read More
Using the camera mounted cleverly by Matthew’s camera mount apparatus, I took a collection of test photographs and determined that the image must be flipped vertically and horizontally to perfectly represent what the robot is looking at. The piece of paper in the image above was placed under the right side of the robot, so...Read More
Matthew worked on designing a static camera mount for the Pi Camera, which will face down at the ground in order to make line following more efficient. We plan to have 2 cameras on the robot, one for line following and another that will stream to a remote machine – however, we still haven’t found...Read More
