PiWars 2024: The Challenges and Their Challenges
There are seven challenges at the in-person event for PiWars 2024, each with their own problems to solve. They are split in to three categories: Autonomous only, Autonomous/Remote, Remote Only. For the second of those, if you are in the Advanced/Professional category you have to attempt the challenge autonomously. State of the Onion NE-Five exists […]
NE-Five Upgraded? Yukon Bet On It!
Upgrades galore in this latest post! Raspberry Pi 5, Pimoroni Yukon, and a banging sound system?!
NE-Five Mk4 – It’s All About That Base…
An update on the design of NE-Five Mk4
NE-Five (Re)design, Lessons Learned
One common questions I get asked about NE-Five is “is it open source” and I always give the answer “mostly…”, there’s a reason for that. The code has been available for a long while, along with a basic simulation that you can run in Gazebo, but the CAD model has never been shared. That’s becuase […]
Making the RedBoard Work on the Raspberry Pi 5
I’ve been using Red Robotics excellent RedBoard for years now, and while upgrading NE-Five to use a Raspberry Pi 5 I discovered breaking changes which means the available libraries wont work. Basically, the way that GPIO works on the Raspberry Pi 5 is different as it uses its shiny new RP1 chip to wrangle its […]
PiWars 2022!
So, for those who follow me on Twitter will know I’ve been accepted to PiWars 2022! The theme for this year is agritech, something I have a bit of experience with from my time at my old company. Here is a list of challenges, there’s three arena challenges plus a freeform obstacle course of our […]
MacFeegle Prime, Lessons Learned, and PiWars 2021!
Using The RedBoard+ From Within a Docker Container…
…because why do anything the easy way? I’ve switched to using the StereoPi image for MacFeegle Prime as it offers the lowest latency for streaming video, the downside is I can’t get ROS to build on it so I’m using Docker which needs to interface with hardware… I’m using the RedBoard+ by Red Robotics, it […]
Raspberry Pi – Docker on USB Drive
As per my last post I’m using Docker on my robot with ROS. The last task is to get docker running from a dedicated USB drive to split resources between that and the SD card the OS is running from. A good guide to mounting a USB drive can be found here. Note, rather than […]
StereoPi Image Mods
I’ve been using the Ubiquity Robotics Raspberry Pi ROS image to run both the robot and controller, it seemed the easiest way to get ROS running, but now I’m trying to get low latency streaming working from the cameras it is proving tricky. New Plan, use the Stereo Pi image with Docker to host ROS […]
