Introduction
To create a multi-tasking device that should be user friendly even for physically handicapped people.
To create a device that should be helpful for the people to move heavy loads in their daily life.
To create a robotic device which can be controlled by using gestures unlike a traditional remote controlled device.

AT89S52
The AT89S52 is a low power high performance CMOS 8-bit micro
computer, and it is designed using Atmel’s high-density nonvolatile
memory technology.
The main advantages of 89s52 over 8051 are
1.Software Compatibility
2.Program Compatibility
3.Rewritability
The 89s52 micro controller has an excellent software compatibility,
Program compatibility is the major advantage in 89S52.

MEMS Micro-Electro-Mechanical accelerometer Sensor (MEMS) is the
integration of mechanical elements, sensors, actuators, and electronics
on a common silicon substrate through micro fabrication technology.
Three-axis accelerometers measure acceleration in three directions.
The MEMS we use in our project is ADXL335 .

DC Motors
DC Motors are widely used in robotics because of
their small size and high energy output.
Key characteristics of DC motors include:
1. High Speed
2. Low Torque
3. Reversibility

Advantages
Easy to operate
Low power consumption
User friendly
Single equipment = multiple applications
When extended further in the hardware section ,numerous applications can be added
![Page 18: Mems based hand gesture controlled robot](https://reader033.vdocument.in/reader033/viewer/2022042522/55a1fcae1a28ab054c8b461d/html5/thumbnails/18.jpg)
Applications Plays a major role in helping very weak people in their
daily life.
Can be used as an assistance for physically challenged people.
Military applications
General purpose device for better living
Useful for moving heavy loads from one place to another.

Conclusion
By using MEMS Sensors, the Robot can be
controlled effectively and efficiently. MEMS are
very useful because, all the individual sensors
can be integrated on a single chip. Moreover, the
power consumption of MEMS is low.
MEMS are made up of components that are of
0.001 to 0.1mm in size and this os the main
advantages of MEMS Sensors for choosing them
to control the robot using hand gestures.
