Inverse Kinematics Tutorial Introduction What is Inverse kinematics in robotics? With your robot having legs the position of those legs dictates where its feet are. Where its feet are dictate its point of balance. As you …

This Simple Hexapod Robot is more like a downgrade from my last robot. The quadruped robot I was trying to build didn’t actually quite work though I spent quite a lot of time, but I have …

Visual Basic Arduino. So, Why? When we are debugging and testing our circuits and codings, most of the times we reset the Arduino board and upload the new program. But the thing is everything has a …

Arduino HC-SR04 The Arduino HC-SR04 is different from most of those commonly seen on the market, which have 4 pins compared to 3 pins. But the operation principle is the same, transmit signal, and depends …

My First ever Robot. It tracks objects using Infra-red sensors, and has basic AI that follows and avoid objects. I will describe the how I made this robot, and upload some videos.

Let’s have a look at the result! Check our my last tutorial to see how it works (theory and example). https://oscarliang.com/infra-red-detection-and-photo-transistor-testing/

IR is invisible to human eyes.  There are two main frequency IR emitters are used: 850nm and 950nm. however for detector, the detectable range covers both frequencies. As we can’t see IR, one way to …

This one hasn’t got too much technical stuff involved, all the operations are from previous tutorials. The main things would be the turning head that I made purely from cardboard, and a couple of screws.
