Back from the Christmas break with a quick update, the team has not only been working hard expanding the Makerspace and drinking it’s Mead, but also working on Tractorbot 2019. Matt and Jon have been testing the motor controllers with the new wheels. In our latest video we show off the strafe capability.
PCBs arrived from jlpcb.com, looking pretty good. OK so they are a bit wrong in places and not well labelled, but we got them quickly 🙂 Im sure it can be quickly adjusted if needs. These were 10 fro $10 including DHL shipping in 5 days! which I can hardly believe.
They fit in the old robot chassis, and I am told motors are working!
This weekends progress….
Mal had made a proposal to upgrade the Nerf gun for the Space Invaders Challenge! At a firing rate of about 6 per second, “The Judge” can output 30 shots into its enemy in well, not much time at all.
More seriously though, v0...Read More
The team is making progress..
Inbetween procrastinating and discussing how to build a 22ft Stargate Christmas Tree, the team has actually been making some progress.
Mal has been prototyping some Pi HAT modifications from the last year design to accept a (physically) larger I2C expander, time of flight sensors and dedicated servo connectors.
We started with Matt’s sketch..
After some...Read More
Yes! Ipswich Makerspace is back again! This time with a tweaked team and a tweaked robot.
This years Pi Wars joins NASA in marking the 50th anniversary of the Apollo Program that landed American astronauts on the moon between July 1969 and December 1972.
The 2019 competitors will navigate “The Canyons of Mars”, autonomously visit the 4 coloured corners of the “Hubble Telescope Nebula Challenge” an...Read More

One thing that has cropped up each year with our robot has been wiring issues. This comes about due to the modular nature of our bot.
We can swap modules based on the challenge we are doing. This has normally led to needing to swap wires around in a very cramped space.
This year the team have decided to replace as much of the wiering as possible with custom made Printed Circuit Boards (or PCB’s).Read More
The below clip shows another example of our colour detection script running on the Raspberry Pi.
We have used C++ and Open CV to detect the colour at a certain position in the frame.
The colour is then show in the top left corner of the video.
This will also be shown on a tiny OLED screen on the body of the robot.
Since our robot base is staying much the same as last years, we have been working on modules that can be switched for each competition.
We need our robot to hold and fire Nerf Darts.
Our excellent team engineer has been working his magic with a 3d printer and a lot of patience to create us just what we need!
Above you can see the 3d rendering of our robot and mount...Read More
