Advanced Trolley with on Spot Billing - by Pashupati Nath Mishra, B.Tech.student

Nowadays, in shopping mall for purchasing a variety of items trolley is required. A customer has to pull the trolley from rack to rack for collecting items and at the same time customer has to do calculation of those items and need to compare it with his budget in pocket. Again, the customer has to wait in queue for billing.

So, to avoid headache like pulling trolley, waiting in billing queue, thinking about budget, Pashupati has introduced a new concept "ADVANCED TROLLEY FOR MALL".

It's a microcontroller based TROLLEY which is totally automatic. It follows the customer while purchasing items and "it maintains safe distance between customer and itself".


Advanced trolley has an artificial intelligence of tracking the customer path request. If the track has been set then there is no need of manual function. That's why the customer needs less effort to pull trolley and gets "on-the-spot billing facility".

Other benefits


Adoption by every major grocery store chain in India and other countries.
