About Ravi

Ravi is a french acronym for Robotics, Learning, Vision and Integration. The initial aim of this project was to provide an environment for research in Computer Vision in Robotics.

We were looking for a full-fledged programming language (not only a scripting language) powerfull enough for image processing, control of mobile robots, trajectory planning, and reasoing about actions and plans. No single programming language is well adapted for all this - some languages are better for tasks like image processing, others for Artificial Intelligence tasks. For this reason we decided to create a n open multilanguage platform with low-level and high-level languages.

We think that such a tool can be very usefull for many purposes, not only for Computer Vision and Robotics.

Features

Here is a summary of the main features of the Ravi system:

• Virtual machine based architecture
• Scheme interpreter written in scheme
• Byte code compiler
• Dynamic loading of C/C++ libraries
• Automatic generation of C++ interfaces
• Dynamic loading of new types
• Type driven garbage collector that can handle C++ objects and external memory management methods (i.e. reference counting).
• Prolog and Production System available

About this site

This site is automatically generated with the Ravi's scheme interpreter using a "scheme markup language" which allow us to insert scheme commands in a source text and so generating documents in Html, texinfo or LaTeX formats with a nice design.

On the home page the background of the image is a part of Ravi's scheme interpreter.

All the graphics are by gimp.
