Program Robots with JavaScript

Rosnodejs is a Node.js module that lets you use JavaScript to interact with the Robot Operating System, an open-source robot framework used by many of the top universities and research programs around the world.

The slides were originally presented at a Node.js Meetup in Austin, Tx.

Transcript

1. How many of you have developed a web app?
2. How many of you think robots are cool?
3. How many of you have programmed a robot?
4. Programs robots Likes robots
5. Introducing rosnodejs
7. ROS = Robot Operating System
8. Not actually an operating system
9. More like a framework
10. Used in...
14. How does it work?
15. It’s a giant graph of nodes
16. It’s a giant graph of nodes (not the V8 kind)
17. A node could...
18. Process 3D data from a Kinect sensor
19. Direct the motors on an Arduino
20. Each node publishes or subscribes to messages
21. ROS is Pub / Sub for Robots
22. rosnodejs write ROS nodes with JavaScript
23. Node.js & Browser
24. XML-RPC and TCP to talk to ROS nodes
25. REST and Socket.IO to talk to server (robot)
26. Uses CORS
27. How To: Publish a Message
28. var ros = require(‘rosnodejs’); ros.types([ ‘std_msgs/String’ ], function(String) { // ... } ); Fetch message type
29. var node = ros.node(‘keyboard’); node.topics([{ topic: ‘talker’ , messageType: String }], function(talker) { // ... }); Create a ROS node
30. var message = new String({ data: 'howdy' }); talker.publish(message); Publish the message
31. What I learned
32. Backbone in the browser Good
33. Backbone in Node.js Bad
34. Backbone’s events only confuse things
35. The Future
36. Infrastructure as a Service
37. Platform as a Service
38. Robots as a Service
