The document describes a hand gesture controlled robot that uses a hand glove with an MPU-6050 gyroscope/accelerometer sensor and Arduino board to wirelessly control a receiving robot car chassis. The transmitter sends gesture movement data via nRF24L01 modules to the receiver Arduino, which uses the data and an L298N motor driver to control the car's two DC motors. Potential applications include remote control of devices, industrial equipment, military robotics, medical procedures, and construction.

3. Introduction
The decision of making a gesture controlled robot that will be operated
by a hand gloved mounted with the transmission circuit assembly. The
circuit assembly will consist of MPU-6050 Gyro Accelerometer sensor
for direction control & Arduino board along with a nRF24L01 RF
module to establish remote communication (data transfer) which
together function as a input device to the bot.

4. AIM
Where human intervention is not possible or is not desirable(e.g.
2013 Savar building collapse), as in the case of spying(e.g. July 2016
Dhaka attack ), so at those places we can use service bots and control
the movement.
85% of people with disability are found in developing countries and
about 10% of Bangladeshi population are affected, here service bots
become handy.
We can use it in Warfield for bomb detection, enemy search, etc.
