Using a Kalman filter on a single analog channel

Things have been slow here at YardBot HQ recently. Not only do I work full time as a mobile software developer, but part time I work for a mechanical engineering company (same building and owners) that will be releasing a

Building Arduino firmware with CMake and catkin

As projects get more complex, the tools you use start to become somewhat unwieldy, and they are no longer as effective as before. YardBot runs with 2 Arduinos, and currently my process for updating their firmware requires starting an Ubuntu

Open loop DC motor control with a PS3 controller

The next stage of my robot project is to make software talk to hardware. Previously I mentioned how I translate PS3 controller data into something useful for a robot. Before getting into complex real-world control, I wanted to check that

Writing a custom joystick teleop node for ROS

I’m learning a lot about ROS with every component I add to YardBot but one of the things I haven’t done yet, and will be required to do lots of, is make a custom C++ node for controlling systems. The

Prototyping part of the electronic system with Arduino

When I started this project I knew I couldn’t attack it all at once. This was for reasons of time, money and tool access so I have to pick away at it whenever I can. Currently that means working on

Creating a standalone ROS computer system

The brain of a robot is very important. In my case, YardBot is an excuse to learn the ins and outs of ROS, or Robot Operating System. ROS is a framework for allowing robot components to talk to each other

Meet YardBot

Robots. They’ve been around for a while, but thanks to the quickening pace of technology progress, they’re only starting to hit their stride. I built LEGO Mindstorms robots many years ago, and working for a robotics company was a dream
