Using WebSockets with Android to control Arduino robots

I just came back from DroidCon 2012 by hasgeek, where I gave a talk about using WebSockets with Android to control Arduino based robots. I talked about WebSockets, how it can be used with Android and then gave a demo that I made using WebSockets, Android and the node.js server which I wrote for jsFoo. The demo allowed anyone from the audience to control an Arduino based robot which I placed in the stage.

I didn’t just talk about making Android and Arduino talk to each other, since I have already covered that in last year’s DroidCon.

Slides

You can download the slides from my slideshare account or view them below.

Demo

I built the demo using WebSockets, Android and node.js which allowed anyone from the audience to control the Arduino robot that I placed in the stage. The user’s browser communicated with the node.js server using Socket.IO and the Android app received this information through socket.IO and controlled the Arduino using ADK. You can find the entire source code in my github account.

The demo was well received and it was good to know that many people liked it. You can checkout some of these tweets to know how much people liked it :)

Arduino Workshop

As I said before, I am conducting an Arduino workshop this weekend. The workshop consists of hands-on sessions, where you can learn about Arduino and then use that knowledge to build a fully autonomously bot from scratch similar to the one that showed in the demo. You can find more details about the workshop from the workshop page at hardwarefun.

Buying Arduino in Bangalore

As it used to happen in my other talks about Arduino, even today lot of people asked me about places where they can buy Arduino in Bangalore. I have already collect a list of places from where you can buy Arduino in Bangalore. You can refer to that page, in case you are planning to buy Arduino in Bangalore.

Couple of people asked me what’s next and someone suggested that I build two robots, that can interact with each other. My personal favorite is to create a bot, that can fly. Let’s see what I make next ;)

Building Robots using Arduino and Android at DroidCon

I just came back from yet another amazing event by HasGeek. This time it is DroidCon.

DroidCon

DroidCon is a developer conference and is part of world’s largest series of Android conferences. It happened at Bangalore on 18th and 19th of November.

Slides from my talk

I gave a talk about building robots using Android and Arduino. I explored the different ways by which you can make both Android and Arduino talk to each other, concentrating on the advantages and disadvantages of the different approaches.

When I find some free time, I will write about these approaches in more detail with code samples for each of them. So stay tuned :)

You can find the slides from my talk below.

Demo Video

Thanks to Arun for shooting this video

Demo source code

I also showed demo of my pet bot Asimi (more details about her later). You can download the source code and learn more about the bot from its homepage.

Update

Here is the video of my talk.
