Basic Buzz Concepts
Development, Compilation, and Deployment of Buzz Scripts
A dynamic extension language. Buzz is a dynamic language that allows one to express complex swarm behaviors with concise scripts. Buzz is designed as an extension language. The task of an extension language is to allow the programmer to work at a higher level of abstraction with respect to that of the underlying system.

Calculation of a Distance Gradient
The aim of this code is to have a group of robots form a distance gradient from a source.
There is one robot that acts as the source; for simplicity here it is the robot with id 0. Every robot, including the source, emits its estimated distance from the source, a listens to other robots.
* The robots that can see the source directly emit the distance they sense;
* The robots that cannot see the source are in two categories:text/html2019-04-05T13:31:25+00:00Anonymous (anonymous@undisclosed.example.com)buzz_kh4

Buzz on the Khepera IV
The Khepera IV is a commercial robot produced by K-Team.
A Buzz port for the Khepera IV is available at <https://github.com/MISTLab/BuzzKH4>. An ARGoS plugin to simulate the robot is available at <https://github.com/ilpincy/argos3-kheperaiv>.

Variables
Buzz is a dynamically typed language. This means that the type of a variable can change during the execution of a script, and it depends on the type of the value stored by a variable at any moment.
Buzz does not include the concept of constant. Every variable is always mutable.text/html2017-01-05T04:02:22+00:00Anonymous (anonymous@undisclosed.example.com)buzz_news

The Buzz Virtual Machine
The purpose of the Buzz Virtual Machine (BVM) is to collect sensor data, process incoming messages, execute a portion of the uploaded bytecode, apply values to the robot's actuators, and send messages to nearby robots. As shown in the picture on the left, to perform these tasks the BVM is formed by a number of interconnected components.text/html2017-09-19T19:22:11+00:00Anonymous (anonymous@undisclosed.example.com)start
