Most processors have interrupts. Interrupts let you respond to “external/internal” events while doing something else. This article uses concepts that have been covered in the previous post “AVR Di...
Robotics Theory - 2D Robotics
Introduction Coordinate Transformation in 2D The motion of manipulators and robots is often very complex and mathematically demanding. A single coordinate frame usually isn’t sufficient, and its o...
Hands On with AVR - 03 Timers
The ATmega328p has two 8 bit timers and one 16 bit timer. Each timer has multiple modes of working. We will be covering all the timers together in the tutorial, one mode at a time. Timers & Pr...
Hands On with AVR - 01 Port Manipulation
Port Manipulation refers to the technique of directly working with the underlying registers of the ATmega chip(in this context) instead of relying on predefined Arduino functions. This is primarily...
Underwater Rover
The primary objective of this project was to build an underwater rover platform that can be used to experiment with topics ranging from control systems and computer vision to embedded systems and...
Spherical Robot
A project to explore the use cases and challenges of using a spherical robot for omnidirectional traversal. Note: This is an old project and has been recently documented, most of the project med...
