Latest Happenings

DD News did a documentary on the design and development of autonomous helicopter at IIT Kanpur.

 

NAAVIK auto-pilot has now been tested and proven on a flybarless 700 class helicopter Align T-Rex. Attitude stabilization, height hold mode, translational rate command, GPS based position hold mode and way point navigation capability has been implemented and tested. 

Autonomous Mini Helicopter IIT Kanpur
 
Payload / package delivery system for aerial logistics has been developed at IIT Kanpur for the Autonomous RUAV platform. A demonstration of the mechanism is shown in the video below.

Below is the demonstration of aggressive attitude tracking for flipping the helicopter and achieving autonomous inverted flight. This work is joint effort between IIT Kanpur (Dr. Mangal Kothari and Dr. Abhishek) and IIT Bombay (Prof. Ravi Banavar).

 

NAAVIK autopilot has been now enhanced to enable autonomous autorotations for our unmanned helicopter. This work is possibly only third such effort after Stanford University and Georgia Tech, USA to demonstrate this capability. Further, this makes use of a novel and simpler approach to autorotation without the need for deep / reinforced learning methods, which was the basis of all earlier efforts. The most common use of autorotation in helicopters is to safely land the aircraft in the event of an engine / transmission failure or tail-rotor failure. It is a common emergency procedure taught to helicopter pilots as part of their training. See the video below:

 

 

Check out the video of flight test of Biplane-tailsitter Quadrotor VTOL UAV. It is one of the various VTOL solutions under development in our lab.

NAAVIK is the new autopilot being developed for cross-platform operations. It has already been tested on a fixed wing UAV for fully autonomous flight. It has also been tested on coaxial MAV, flapping wing MAV and Quadrotor. Objective is to develop NAAVIK for application on wide range of UAV platforms.
