A Review Article on Automated Trolley

Our project focuses on benefit of the society and bringing automation in the field of weight carriage particularly trolley which is not in existence that is widely used by masses in airports, railway stations, colleges .After undergoing a survey on existing automation in trolleys we have come up with new ideas to benefit all the particulars. Our goal is to solace every individuals effort by making trolleys run automatically with use of PIR Sensor, Accelerometer , Bluetooth module, remote and speed adjuster at different situations .When the place is less crowded, one can make use of PIR Sensor to automatically follow human within its range or using Accelerometer and guiding the trolley with directions it must move and when there is a considerable crowd, one can use his own mobile’s app which uses Bluetooth to make it follow his device. Secondly use of remote when observed an intermediate crowd making it to move in front of one’s vision. Thirdly in more crowded areas, it’s about adjusting speed of the motor using button in handle and pulling the trolley as usual but without feeling load of the trolley since the wheels are in slow motion which holds the load and leaves less effort for the owner to drag it.
