Accelerometer Based Hand Gesture Recognition and Control of Motor Powered Trolley

Abstract

The passengers and workers always prefer the wheeled trolley due to its ease of transporting goods. It is still challenging for the old people to manage themselves and the trolley. This paper presents the insight of the hand gesture-based smart control of trolley with speed variation to match the user requirements. There is a lot of scope in this area to improve the smartness of control, but this work gives a complete description of the hardware equipment's design idea and experimental values. It uses an accelerometer (ADXL-335) to sense the hand gesture and sends them to the receiver through a wireless RF transmitter. An L293D driver drives the motors in the receiver with proper motor wiring to ensure the progression of the trolley as per the command received by the RF receiver.
