A custom-built lego machine for playing pong, featuring two controllers connected to the Mindstorms NXT brick. Programmed using NXC.

Developing in NXC using XCode

After comparing a number of options, I chose NXC as a pretty good alternative to Robot-C. It supports a lot of things like sensor and motor management, playing of sounds, basic 2D and 3D graphics, etc. Most importantly, you can compile your programs from the command line or from XCode. This tutorial assumes knowledge of XCode 4 and of C. The NXC programming guide is a good reference.

Setting up NXC Development on a Mac

This tutorial provides a step-by-step guide for setting up your Mac or Linux machine and your NXT brick for development with NXC. We will use the enhanced NXC firmware in order to enable extended functions for development.


The main purpose of pyCreeper is to wrap tens of lines of python code, required to produce graphs that look good for a publication, into functions. It takes away your need to understand various quirks of matplotlib and gives you back ready-to-use and well-documented code.

Citations count fails to measure the impact of research

Academic career progress is often judged by so-called "h-index", that measures how much your research is being cited. I recently had a detailed look at what exactly the citations, specifically those reported by Google Scholar, amount to. Only a relatively small fraction of the reported citations corresponded to research being applied or reproduced in a meaningful way.

V-REP, Gazebo or ARGoS? A robot simulators comparison

Let’s have a look at three commonly used open-source simulators for robotics: V-REP, Gazebo and ARGoS, to find out which one suits your project the best.
