IOBOT : Build your own Azure powered Robots

2nd Prize winner of Microsoft Azure IoT contest

Building robots from the scratch with speech recognition, remote voice control, learning intelligence with Raspberry PI, Intel Galileo and Microsoft Azure.

It was in my previous article on Internet of Things, I have mentioned that "making robots moving around without hitting each other is not easy". But, wait! Is that really not easy? may be yes or may be not that hard. But why not try building one by our own to see how it works. This article is an attempt to build two small robots which can interact with human as well as within each other. We are going to do almost everything from the scratch. Just imagine the Sonny character from I Robot movie. No, we are not going to do that. But, up to some level where our robot can respond to our commands and learn new commands, communicate with other robot etc., then you can extend this to any level as you wish. Sky is the limit for your imagination.


Internet of Things: Programming IoT Devices, Web Services and IoT Clients

A complete walk through on IoT Device programming, Web Service programming and IoT Client programming.

Internet of Things – There are many articles to explain about “IoT” out there on the internet, so we are not going deeper into what it is. In a simple term “Internet of Things – Making devices work based on connected data through internet”. The data source can be from a sensor, a web server, another device, a mobile phone or any form of an electronic device which can receive/send data through internet. So “Internet of Devices” + “Internet of Data” = “Internet of Things”. Is it that simple? Yes, it is, as long as you are thinking of clicking a button from your office to switch off your TV at home. But, if you want to build a bunch of devices to act and react to each other based on data it receives from each other like robots moving around without hitting each other, automatic cars moving on roads without any accidents, it is not that simple, isn’t it? Rome was not built in a day. This article is to give you some bricks to start building now.
