Development of Zigbee based tele operated multipurpose robotic arm with hand gesture recognition

Abstract

The integration of technologies like Electronics and Mechanical has emerged a new branch which is most famously called Mechatronics. Robotics is a part of Mechatronics. Robotics refers to duplication of human actions by machines. Robotics is a very vast field that has helped us make some wonderful machines that assist us in our daily lives. Typical industrial robots usually perform tasks that are difficult, dangerous and too complex. They lift heavy weights, and a lot of manual work such as welding can be done using robots. They can perform the same course of action in lesser time with more accuracy. Many people have used various technologies to build such kind of robotic arm with wired or wireless communication methodologies. This proposed robotic arm is focused on developing a system that works wirelessly to recognize and control the robotic arm by using various methodologies such as hand gesture recognition technology, Zigbee wireless communication technology, MEMS-3 axis accelerometers, flex sensors etc. The combination of such latest technologies in a single platform has posed real challenge to design and develop. Hence, this work is undertaken to design and develop Zigbee based tele-operated multipurpose robotic arm with gesture recognition. Though the working of a robotic arm is very simplified, the implementation of this arm requires a good knowledge of Engineering Mechanics, Arduino platform, High end Atmega328 AVR RISC microcontroller, Electromechanical Devices mainly sensors, Mechanical Robotic Arm setup, Rover assembly and Embedded Systems as well.
