The development of karelNXT robot as a simulation of xkarel programming language

Abstract

The article is dealing with programming of a robot KarelNXT made from a LEGO construction set. The idea comes from xKarel programming language, which is a traditional programming language utilizing a virtual robot only shown on a screen. The virtual xKarel programming language was extended by its implementation in LEGO Mindstorm NXT-G integrated development environment. Real robots built from LEGO construction sets use additional sensors in order to make possible building of a robot with equal functions to the robot in xKarel programming language. KarelNXT robot built from LEGO construction set is using the control unit in NXT version. In the article we mention the description of individual robot movement instructions.
