Rakshak

Founder of Harvested Robotics, Rahul Arepaka (22) built Rakshak, an AI-powered laser-weeding robot that combats weeds without harming the crops. He is now using it to help farmers earn more.

Just like most other festivals in India, the history of Raksha Bandhan is rooted in various mythological legends and folklore.

A mobile app called Rakshak has been launched by Lucknow University to enable students in distress to call for immediate assistance. The app also works outside the campus, and will help the authorities in keeping a check on ragging.
