The main aim of this project is to design a robotic vehicle which is operated wirelessly using MEMS technology. In this we are using ZIGBEE wireless communication between hand gesture and Robotic vehicle. Zigbee is a PAN technology based on the IEEE 802.15.4 standard. Unlike Bluetooth or wireless USB devices, Zigbee devices have the ability to form a mesh network between nodes. Meshing is a type of daisy chaining from one device to another. This technique allows the short range of an individual node to be expanded and multiplied, covering a much larger area. This project makes a use of MEMS, Zigbee TX, Zigbee RX, Arduino nano, PIC Microcontroller, DC motors along with l293d motor driver with robot chassis. The MEMS sensor is uses for rotational velocity along the X, Y, Z axes to control the all direction of the robot such as left, right, forward, backward and stop. We fix a MEMS sensor on glove. Based on the hand gesture, these values are fed to the Arduino nano microcontroller. This data is transmitting with the help of Zigbee transmitter module and received by Zigbee receiver and fed as same to the Microcontroller. The DC motors along with l293d motor driver are interfaced to the PIC microcontroller. Based on the received data microcontroller control the direction of robotic vehicle. To achieve this task microcontroller loaded program written in embedded C language.
