WIRELESS ROBOT NAVIGATION IN MICRO-CLIMATIC ENVIRONMENT
[attachment=24061]
Abstract:
In the recent years, unmanned exploration of extra-terrestrial and uninhabited regions has become more common.
Land rover type robots are exclusively for this purpose.
The project involves the design of a PIC 16F877A microcontroller based environment monitoring robot with climate sensing capabilities for use in a microclimatic environment.
The robot is a land rover type model with DC motor based wheel movement.
The robot is maneuvered using a control and data processing system designed using Atmel AT89S52 microcontroller. The microcontroller is interfaced to a keypad and LCD display. They act as the input and output devices to the control system.
The control system acts as a command center with robot motion control and climate measurements. There is a special feature for this robot namely path-retrace which enables it to return to the starting point.
Introduction:
Sensor networks consist of physical sensing devices.
A model for algorithm support is analyzed for interfacing sensors to WSN.
PIC microcontroller,embedded sensor board, implement intelligence and grid function of sensor.
NODE A
A personal computer acts as node A.
Node A acts as the main control center and commands for navigation and sensor measurements.
Tarang F4 ZIGBEE module is interfaced to node A to transmit and receive data.
Various commands are transmitted through the serial port from node A to node B through the serial port. The characters are F-forward, L-left, R-right, B-backward, P-path retrace, T-temperature and C-Co2 gas
Node B
Node B is a land rover type robotic vehicle controlled and maneuvered by node A.
A 12V/7A Lead acid battery provides power to the vehicle which uses 2 geared motor based wheels controlled by relays for its movement.
The temperature and CO2 sensors are connected to the ADC pins of the PIC 16F877A microcontroller.
DS1307 IC is the real-time clock chip used to generate the time period.
The built-in EEPROM is used to record time and direction of movement so that it can be retrieved to perform path retrace.
ZIGBEE-TARANG F4
FEATURES
Modules operates with ISM 2.4 to 2.4835 GHz frequency with IEEE 802.15.4 Baseband.
Point - Point, Point - Multi-point and Peer – Peer topologies are possible.
It can be interfaced to a micro-controller or PC.
Outdoor line of sight range up to 50kms & Indoor line of sight up to 400m
