This system comes into the recognition mode. In this mode when a voice command input through the microphone will be again converted into an 8 bit pattern and will be compared with the stored pattern. If any match between the patters were found then the voice processor chip will place the corresponding 8 bit numeric code into its data bus . Data bus contents are to be latched. The data bus is interfaced with an 8 bit microcontroller(PIC 16F877A) and the code data accepted by the controller is processed and required commands will be send through-a transceiver-which i:is-based on ZigBee,that is interfaced with USART ; a built in peripheral''facility available with the microcontroller. An LCD display will also be there to verify the integer code. The control commands transmitted through the ZigBee is received by another ZigBee and the signal are processed by another microcontroller. The received codes are decoded at there and appropriate signals are generated to control the motor of the robot car. At the car there is an arm which collect s the waste from the required locations. And the robotic vehicle is attached with a color sensor which provides an output of RGB components .The color-sensor is used to identify the container or locations to which the waste to be deposited. This project is to design a waste bin detecting robot and useitas'a platform for the waste disposal purpose and maintain a clean environment. Sometimes a direct human interaction is hazardous to their health and may cause some severe health problems to the scavengers. This project will help them to overcome such problems. This system can be controlled by voice commands and the robotic arm can collect the waste and put them-to the specified location or containers. |
