I am currently in the process of designing and building a five-axis robot from scratch. I, therefore, also need a gripper to be able to manipulate objects. The drive for the gripper should be a commercially available micro servo, as shown in the following picture. In addition, the gripper should Read more…
I developed a 3D-printed robotic hand during my studies at the Technical University of Munich. I used a 3D printer to build the mechanical parts and a Raspberry Pi Pico for controlling the motors. Background Every four years, ETH Zurich organizes the CYBATHLON competition (cybathlon.ethz.ch), in which teams from all Read more…
In this article, I present the central concept of the robot control of my mobile robot. There are many different variants to structure the software for a robot. I will show you which one I implemented in MOBROB. Direct control The simplest option is the so-called direct control. Here, a Read more…
After I presented the hardware architecture in an earlier article, I want to dedicate this article to the software architecture of my mobile robot MOBROB. The software architecture is based on Robot Operating System (ROS), which allows me to extend the robot very modularly by functions. There are a lot Read more…
After a long time has passed, here is an update on the current major project MOBROB. My completely self-built mobile robot. In the last post, I introduced the basic functions. The next step is to place the complete electronics nicely on the robot, so that there is still enough space Read more…
I started to build my first mobile robot with Mecanum Wheels a few weeks ago. In this post, I would like to show a look at the hardware structure. The software is an ongoing process and will be a topic in several future articles. Parts for the mobile robot I Read more…
This model is one of my first self-made projects. At that time (2011) I tried to build a robot that can only move on its legs. I used the legs of a spider to design the mechanics, but I only wanted to use one motor per leg. So I had Read more…
In high school, I was part of my high school’s Student Engineering Academy (SIA). As part of this cooperation model between school, university and industry, I learned about many aspects of engineering. We visited different companies and were taught disciplines such as programming, design, and electronics based on a central Read more…
The starting point of my new project was the fact that I bought my own small 3D printer and now thought about what I can build with this printer. It should be a complex mechanical project, but it should also be automated. I came up with the idea to build Read more…
This is my most popular video on YouTube with more than 175.000 clicks. It is a special truck called the underbridge unit as it mainly used to do work below a bridge, while the truck stands on the bridge itself. My model built out of Lego Technic has the following Read more…
