Rostalk

=======

Rostalk is a ROS client implemented in Amber Smalltalk that used rosjs (ROS javascript binding) and rosbridge. The main idea of Rostalk is to be able to develop and control robotic systems on the web with a high-level language like Smalltalk instead of using JavaScript.

Amber Smalltalk (previously known as jtalk) is an implementation of the Smalltalk language that runs on top of the JavaScript runtime. It is designed to make client-side development faster and easier. Amber is written in itself, including the parser and compiler. Amber compiles into efficient JavaScript, mapping one-to-one with the equivalent JavaScript. There is no interpretation at runtime.

    ./bin/server

Setup your ROS environment

==========================

### Install ROS Electric

### Install ROSBridge

    

    apt-get install ros-electric-brown-remotelab

### Start up a roscore, if you haven't already:

### Launch rosbridge to connect ROS to rosjs:

    rosrun rosbridge rosbridge.py

### Launch your favorite web browser (supporting Websocket) on http://localhost:4000/rostalk.html in your favorite webserver.

Try a first example
