This is a motorized device, which picks up littered pieces of wrappers, papers, pouches, etc and collects them in a storage bin.

The brothers thought about this device when they saw a sweeper picking up waste pouches/ paper littered across a bus station. They realised how difficult it must be for him to bend every time to pick up such pieces.

With keen interest in science, both the brothers participate in a lot of science competitions and exhibitions. Diptanshu likes reading biographies of scientists and inventors and wants to serve ISRO when he grows up. His brother, Mukul also has similar interests and wants to become an engineer.
