If you are looking for a STM32F3 board for your next project it might just be worth your while to consider the SP Racing F3 board. In a previous post I discussed how you can program an old Naze32 flight controller board using Arduino. While writing it I also looked at some other low cost […]

# First steps with ROS

As with many other complex problems, we can often solve and handle robotic problems more effectively if we break them up into smaller pieces. One way to achieve this is by using ROS (Robot Operating System), which promotes a more distributed design approach. The basic idea is that we break the project up into smaller […]

# Modelling an inverted pendulum

Aim Accurately model an inverted pendulum to use for control algorithms development for physical implementation. Personal goal: refresh basic understanding of modelling and control. Newton’s law The cornerstone for obtaining a mathematical model, or the equations of motion for any mechanical system is Newton’s law [1] F = the vector sum of all forces applied […]

# Blob detection and tracking

In an upcoming project I want to experiment with image recognition and have a balance robot track and follow a colored ball. As a prelude to that project and to learn more about what is involved in terms of the image processing I came up with a smaller sub project. The idea is to just […]

# Attitude estimation using IMU sensors

In this post I want to talk a bit about the use of accelerometer and gyroscope sensors to perform attitude (roll, pitch and yaw) estimations. Systems that perform these kind of tasks are often referred to as AHRS (Attitude and Heading Reference System) and is commonly used where it is important to know the attitude […]
