Here's the stellar work done by four IITians who built 'Drone Rancho' for the famous movie '3 idiots'

The makers of the drone 'Rancho' seen in the movie 3 idiots have created several unmanned aerial vehicles that are being used by Indian defence forces and in intelligence and surveillance ops.

A team of four IIT alumni - Ankit Mehta, Rahul Singh, Ashish Bhat, and Vipul Joshi - started a company called ideaForge in 2007 to give their dream wings. They were working on developing technologies back in college and had many ideas they wanted to convert into products by the time they graduated.

In 2008, recognition from government came to them when they won a Micro Aerial Vehicle competition at Massachusetts Institute of Technology, USA. Thereafter, they landed with several government projects, one of which wa NETRA – a vertical takeoff and landing UAV built on quadrotor configuration that the team developed in collaboration with Defence Research and Development Organisation.

This UAV could take off from a small area and could fly over an area up to the height of 400m sending continuous real time videos of movements on the ground. It was this early prototype of NETRA that you had seen during the shoot of 3 Idiots. The movie director of 3 idiots had read about the drone and work by IITians in the newapaper.

In 2009, ideaForge developed the world’s smallest and lightest autopilot drone and also came up with India’s first fully autonomous vertical takeoff and landing UAV. In this, a user feeds the GPS location of the required destination, which is then converted into command and instructions and the UAV reaches the location autonomously.

The UAV's made by this team are typically easy-to-use, so they can be used easily during emergencies. So far, they have been used by the Indian Army to look for survivors after the deadly Uttarakhand floods back in 2013, to map the positions of militants during defence ops, for disaster management during the Nepal earthquake, and to manage crowds during the Kumbh mela. One of ideaForge’s drones also helped in tracking a man-eating tigress in Uttarakhand.
