WHY THE AVR FAMILY?8051

AVR

8 bit micro based on CISC architecture.

8051 family is slower as compared to AVR.

Does not have a ADC. Instruction set is

large.

JTAG interface absent.

8 bit micro based on RISC architecture.

AVR's are fast, consume little power, are rugged.

It has an inbuilt 10-bit ADC.

Instruction set is simple and compact.

JTAG interface present.

Remote Terminal Used for an authorised client’s access to

robot.

Has a JAVA based client applet running on it. Moniters the temperature. Controls the motions of robot.

Server Machine Acts as an intermediate between robot and

user . Has a JAVA based server applet running on it. Connected via RS-232 to robot.

Microcontroller (AVR Atmega 32) Converts analog signal from sensor to digital. Sends digital data via UART to server PC. Receives control code from user through

server. Controls robot as per the received code. Detects errors ,if any and sends it to LCD.

Temperature Sensor(LM 35) Is a Precision Centigrade Temperature Sensor

with a sensitivity of 10mV/C. Senses temperature and converts into

equivalent analog voltage between -550 to 1500 mV. Techogroovy Systems India Pvt Ltd ,

Motor Motor used is a DC motor with an output of

1.18W and operates in 6-12V range. Motor is controlled by an H-bridge in the

driver.

Driver(L298) Is an interface between low power(AVR) and

high power(motor) devices. Contains an inbuilt H-bridge controlled by

AVR.

LCD Used to display temperature and to detect

errors in the robot control.Techogroovy Systems India Pvt Ltd ,
