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…
This time I will show how I built the LED light cubes shown in the picture above. I call them TinyLightCube, as they using an ATtiny85 as a microcontroller. The cubes will change their color depending on how they are tilted. Parts For one color cube we need following parts: Read more…
I show you how I build a pretty simple control unit for a fan, which should circulate the air around a heater. I used an Arduino Nano V3.0 as a microcontroller together with two CPUs fans. Requirements The fan shall turn on via a push-button mounted on a wall on Read more…
In this post, I will build a super cool word clock with Arduino and Neopixel LEDs. Such word clocks cost several hundred euros in the trade, but with a little skill, they are also fast self-built. I show you how it works. The electronic base is similar to that of Read more…
In 2014 I have built a model house made of plasterboard and equipped with electric light in every room. Here you can find some photos and videos of the project. Each room has it own lights, which can be turned on with a rotary switch. Highlights are the lights in Read more…
In this article, I document the few steps necessary to control the Wi-Fi switch Shelly 1 with a Siemens LOGO! 8. For this we use the help of the tool Node-RED, which is described on the own website as follows and is therefore perfectly suited for our use-case: Node-RED is Read more…
With this post, I want to start with the description of the software for my mobile robot. One of the first things I’m setting up in the software is an OTA (Over the Air) update function for all my components on the robot. That means besides the Raspberry Pi, I 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…
Table of Contents Introduction Java-Application Python TCP Server on Raspberry Pi Result: Stream video from Raspberry Pi to Java-Application During the development of my mobile robot, I was confronted with the problem of how to transmit the video stream of the robots webcam to my central Java-Application. The structure looks 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…
