Hello,

I decided to change a bit the blog structure. Now, the front page shows an extract from the featured posts and pages, so that you can have a hint at glance to choose what to read.

I hope you like this small enhancement!

Ciao,

Introducing the Sup3r Car

Hi there! Here comes the Sup3r Car, or to better say a slightly modified version of the original Sup3r Car (read Super Car) model designed by Daniele Benedettelli in his fantastic book “The LEGO MINDSTORMS EV3 Laboratory”. Have a look here!

Manual actuators homing for Lego Mindstorms Ev3

Every automated equipment which features at least an actuator must have also a system and a procedure for its actuators homing, and of course, this is also true for our Lego Mindstorms Ev3 robots. In this page, a procedure for manual actuators homing

Ev3 Tracked Explorer Mark II is ready!

Ok, I think that I can finally start to describe this tracked rover I’m working on since maybe March 2018… and it’s December 2018 now! And so, yes, the Ev3 Tracked Explorer Mark II is ready at last! What is

The PID Controller – Part 3 of 4

← Back to Part 1 – Introduction and some math ← Back to Part 2 – Some more math 🙂 → Part 4 – Application to the Ev3 Medium Motor position regulation As described in Part 2, we need a new PIDController class that performs the following computation:

The PID Controller – Part 2

Howdy, In my previous post I introduced the PID controller; this time I’m gonna illustrate how to formulate the algorithm in a way which simplify the coding on board our EV3. This post will be saved as a static page here. I

Drive the Formula Ev3 with the IR Remote!

Today, I present the Formula Ev3: a racing car! Personally I like this model for its very clean profile, which aside from the cables, resembles pretty well a Formula 1 racing car from the eighties. It also features a openable

Latest pictures of the Ev3 Tracked Explor3r vehicle

Today, I finally post the pictures of the Ev3 Tracked Explor3r that I’ve built using the Lego Mindstorms Ev3 and programmed in Python with the Ev3Dev firmware. This model is a MOC (my own creation) so its full building instructions are available here. This model does

The PID Controller – Part 2 of 4

Back to Part 1. So, we’ve got the following equation: , which gives the controller output at each instant . To implement this controller, one thing to do is to consider the , i.e. the increment of the control signal from

The PID Controller – Part 3

Hi there! In my earlier post, I described the equations that drive the PID controller behavior. Finally here is the PID controller implementation. The code is very simple: there are just two things to notice: The thread is executed once

The PID Controller – Part 4

Hi there, In this last post about the PID Controller implementation, I present you the MediumMotorPositionPID class; the MediumMotorPositionPID inherits from the PIDController class and adds the reference to the Ev3 Medium Motor to it. From the Lego website: The EV3 Medium Servo Motor is great for
