Custom Printed Circuit Boards

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).

Colour Detection using OpenCV

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.

Nerf and back again!

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...

Somewhere Over the Rainbow – Colour Detection

One of this years challenges is to detect  some coloured balls from a distance and visit them.

The full details are here. http://piwars.org/2018-competition/challenges/somewhere-over-the-rainbow/

For our robot we are using a Raspberry Pi Camera and OpenCV to detect the colours and some code written in C++.

You can see a video of our robot doing some colour detection below.

Whilst testing this w...

Nerf Assembly – 3D Render

Keith has been working with a tool called “Fusion360” to create the 3d models for our robot. This can then create the 3d printing file as well as laser cutter instructions. However – one other feature is that it allows you to create an animation of the 3d object!

This video shows our Nerf mount!

Nerf gun mount

Keith has been doing some more model work in Fusion360 (not on the cat walk!) So far he has the guts of the Nerf gun launch system and magazine modelled, and work has started on the mount system.  Over the next few weeks hopefully he will get this finished and we can get the parts cut and printed and trial fit them to the bot.
