Dertermining the centre of gravity for a self-balancing robot

This is part of a series of posts covering the development of a self-balancing robot: Modelling an inverted pendulum Building a self-balancing robot This post The mathematical model of an inverter pendulum previously developed for the self-balancing robot, needs three parameters to accurately represent reality. These are Weight of the cart Weight of pendulum And […]

Building a self-balancing robot

This is part of a series of posts covering the development of a self-balancing robot: Modelling an inverted pendulum This post Dertermining the centre of gravity for a self-balancing robot   Previously we investigated how to model an inverted pendulum. It is now time to go ahead and build the actual robot. This robot will […]

Low cost STM32F3 board

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 […]

Programming Naze32 with Arduino

The Naze32 is one of those iconic flight controller boards of the early days of FPV quads. It superseded the 8bit boards of the time and was the board to have. Fast forward to today, flight controller firmware has generally become much more complex with support for new features and increased flight performance. This left […]

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

This is part of a series of posts covering the development of a self-balancing robot: This post Building a self-balancing robot Dertermining the centre of gravity for a self-balancing robot Aim Accurately model an inverted pendulum to use for control algorithms development for physical implementation. Personal goal: refresh basic understanding of modelling and control.   […]

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 […]

Building a UAVCAN Node

Using CAN bus to connect peripherals on a drone has always sounded like a good idea. It is well known for it’s robustness and efficiency in connecting electrical control units in cars together, so it should also be well suited for drones. Flight controllers like the Pixhawk and Cube have always had a CAN bus […]

Multi-protocol Module for RC Models

A couple of weeks ago I was searching for a cheap brushed flight controller, for a mini quad project, and stumbled upon the Beecore Lite. At 26mm x 26mm this little guy featured a STM32F030 MCU with MPU6050 IMU and a built in RC radio receiver. All this for less than 10 Euro from a […]

FPV Racer Build

In recent years the FPV (First Person View) drone racing industry has grown tremendously with tournaments around the world offering up to one million dollars to the fastest pilot! The widespread interest has flooded the market with low cost components that is of decent quality, making it easier and cheaper than ever to get your […]
