or how to combine the outputs of many sensors into one signal — One typical problem when dealing with complex systems such as robots or vehicles which are composed of plenty of sensors with different accuracy is the combination of the generated signals in order to extract the most accurate signal from the whole system. For sure, one thing you can always do…

Improving Scipy.curve_fit through a genetic algorithm — In my previous post System Identification with Python, I noticed that the tool from Scipy called curve_fit() has some limitations in terms of looking for the right solution when the given initial values of the parameters are far from the expected solution. This essentially means that its capacity of exploration…

Essentially, how to write a first Verilog app — In the previous post, I simply wrote a basic summary about how to set the Apio environment to run an example without trying to take a look to the code. The first problem I saw with the platform Apio was the number of available examples at the Github repository, which…

A series about iCE40-HX8K and Robotics — The following series of posts are only a log of my advances on the development of applications of the aforementioned FPGA in the field of Robotics. For myself to track my evolution and write them down before I forgot them. …

Some basic concepts on Life Support Systems (LSS) — For life support systems such as the ones for astronauts, divers or firefighters, it is critical to estimate the air consumption in real time and to monitor the resting air reservoir in order to know how much time do we have before running out of air. The equations for modeling…

Or how to use Scipy to approximate with linear systems — In the previous chapter, we saw how we can make simulations with transfer functions using Scipy and Python, essentially, compared to the simulations with the simulator I designed. There, I took a transfer function to approximate the nonlinear model of the motorized pendulum. Well, in this tutorial we see how…

Another charming hidden place in the province of Cádiz (Spain) — Camposoto is the only beach in San Fernando, the small city where I was born. Since I was a kid, I have spent countless afternoons and complete days there. …

Pendulums and robotics arms are (almost) the same thing — In the previous chapters I have tried to cover almost all the necessary software tools you could need to launch simulations of physic dynamics with Python. …

Magic places in the province of Cádiz (Spain) which you may not find in a tourist guide. — In this post about charming Cádiz hidden places I want to show you another place which does not appear (usually) in tourist guides: the Tarifa island seafloor. Tarifa is a very touristic town placed in the very south of Spain. Indeed, it is the southernmost point of continental Europe. Further…
