Robot control: Educational robots designed at IITB are used to teach principles of embedded software, algorithms incorporating artificial intelligence and data collection from various sensors. An application developed on Aakash allows the tablet to control the movement of the robot and see the video stream from a mounted camera, sent to it using WiFi.
IIT Bombay describes Aakash as an access device in which a Linux environment has been developed atop an Android operating system. Tailored compilers for C, C++, Python and Scilab are ported so that users can write and run programmes on the tablet, emphasising its use as a full-fledged computer. Powered by a 1GHz processor and backed with a 512 MB RAM, Aakash 2 sports a 7" capacitive screen, a USB port and micro SD card slot and promises a battery life of 3 hours for normal operations.
Jharkhand has placed a request for 4.5 lakh devices, out of an overall estimated nationwide demand of nearly 5 million.

The HRD ministry plans to invite tenders for five million upgraded Aakash tablets next month.
