Transcript of Embedded Systems & Robotics
INTRODUCTION TO EMBEDDED SYSTEMS
A combination of hardware and software which together form a component of a larger machine.
An embedded system is designed to run
on its own without human intervention,
and may be required to respond to
events in real time.
An embedded system is designed
to perform a dedicated function.
SOFTWARE
PROGRAMHARDWARE
ESSENTIAL COMPONENTS
Micro Processor
Micro Controller
ARM 7/9/11
PIC 16Fxxx/18Fxxx
MSP 430
Sensors/Actuators
Convertors(ADC/DAC)
MICROPROCESSOR
A microprocessor is a single chip semi conductordevice also which is a computer on chip, but not acomplete computer.
Its CPU contains an ALU, a program counter, a stackpointer, some working register, a clock timing circuitand interrupt circuit on a single chip.
To make complete micro computer, one must addmemory usually ROM and RAM, memory decoder, anoscillator and a number of serial and parallel ports.
MICROCONTROLLER
A microcontroller is a functional computer system-on-a-chip. It contains a processor, memory, andprogrammable input/output peripherals.
Microcontrollers include an integrated CPU, memory(a small amount of RAM, program memory, or both)and peripherals capable of input and output.
SENSORS
A sensor is a Converter that measures a Physical quantity and converts it into a signal which can be read by an observer or by an instrument.
• Cost
-Low Cost .
-Cost Divided to Two Sections :
1) Cost Of Designers And Developer Of
Product .
2) Cost Of Production And Marketing

WHY ROBOTICS? Speed.
It can work hazardous/dangerous environment.
To perform repetitive task.
Efficiency.
Accuracy.
Adaptability.
