Lecturer on Robotics and Biomechanics

Technical University of Cluj-Napoca


My name is Tassos Natsakis and I am lecturer and post-doctoral researcher at the ROCON lab of Technical University of Cluj-Napoca. My background is in Mechanical engineering and I have done extensive research on the biomechanics of human locomotion. More specifically I studied the behaviour of the human foot in-vitro, with the goal to understand and improve surgical procedures and medical implants. I am currently researching in the intersection of the rehabilitation and robotic fields, leading a research project for the development of a robotic rehabilitator.

Besides research, I am very interested in teaching methods, knowledge management and productivity, in an attempt to make my research more efficient, pleasant and easier to explain to others.

Upgrading the robotics laboratory

There is a small paradox at our department: we are teaching robotics to students, but we used to not have any robots around for them to play with. We actually did have one, that is very very dangerous to use close to people, so I slowly slowly phased it out of use. But I had to find an alternative: a small, versatile, cheap, robot arm, that we could buy multiples of it and have one for each table of the laboratory.

Wooden Robot Model

For quite some time now, I wanted to create a robot model to use it in the classroom. I started imagining it as a 3D printed model, then thought of making it out of styrofoam, converted the idea to carton, but was always stopped by the lack of materials around. Also, the fact that we’ve been teaching online for the past year and a half was not helping. Last week, I thought of wood.

Less Wrong Gems 2021

I don’t remember when did it exactly happen, but at some point I landed on a elegant looking community blog that is called Less Wrong. They advertise themselves as “[…] a community dedicated to improving our reasoning and decision-making” and the name is derived by the realisation that in order to learn, we must constantly err, but each time less and less. It is basically a blog where anyone can post essays or ideas on the topic of rationality and real-world applications of it.
