line follower using lpc2148

Abstract

Performance efficient processors have become increasingly important for mobile robots with numerous actuators and sensors. Therefore, this project is to implement a 32-bit low-power ARM processor into the development of a 3WD omni-directional mobile robot equipped with IR sensor capabilities. The scope of the project is narrowed down to the usage of Embedded Artists' LPC2148 USB QuickStart Board, digital fiber sensor, DC brushless motor, and omni-wheel. Most of the tools and necessary equipment for the project development can be obtained within the UTHM. At the end of this project, the ARM processor has successfully generate the desired PWM for motor control and respond to the digital input from the interface of IR sensor to the microcontroller.

Introduction:

In this project is to implement a 32-bit low-power ARM processor into the development of a Mobile Robot using ARM Processor for Line Following Application mobile robot equipped with IR sensor capabilities. The scope of the project is LPC2148 Arm Processor DC brushless motor 100 RPM Motor is used. At the end of this project, the ARM processor has successfully for motor control and respond to the digital input from the interface of IR sensor to the Microcontroller.

Circuit Description:
This project Microprocessor ARM LPC2148 is used, 2*16 LCD module to display the Direction of the Robot and Motor Driver L293D is used. D.C Motor 100 RPM is using in this project, why we use 100RPM motors lesser RPM to control the speed otherwise use PWM Technique to control the speed of the D.C Motor.
Two IR Sensor pair is used to follow the line, one set of IR sensor is used to detect the Obstacles. One IR Transmitter (TX) and 1 IR Receiver (RX) and LM358 two independent, high-gain, frequency-compensated operational amplifiers is used. ARM processors chip that contains two 16 Kbyte, 32-way set associative caches for instructions and data can be used in mostly any domain such as handheld devices, automation system, robotics, and other consumer electronics since it provides comprehensive support required in developing a complete system.
The Hardware’s like LCD and L293D,IR Sensor, Buzzers how to connect the Processor is explain as follows, the 2X16 LCD is used here 4bit mode, the Data Pins are connected D4 to P1.20 and D5 to P1.21,D6 to P1.23,D7 10 P1.24. Register Select R/S P0.10 and Enable Pin P0.13 and R/W directly Connected to GND Pin. The L293D is connected to Input1 to P0.14 and Input2 to P0.15, Input3 to P0.3 and Input4 to P0.4.The obstacle Sensor is connected P0.8, the line following two IR Sensors Left and Right is connected to P0.29 and P0.30 of LPC2148 ARM Processor.
