Study Notes

Robotics Overview

Robotics merges engineering and computer science, focusing on creating, designing, and operating robots.
In the 1930s, George Devol recognized factory automation's potential through magnetic recording technology.
The patented Unimate robot, created in 1954, featured a robotic arm capable of six degrees of freedom.

Electrical Components

Resistor: Passive component regulating electric current flow in circuits.
Variable Resistor: Allows adjustable control over current, commonly used in audio equipment like guitars.
Electrolytic Capacitor: Utilizes an oxide film as a dielectric, ideal for applications requiring significant capacitance, especially in power supplies.
Ceramic Capacitor: Fixed capacitor using ceramic material as dielectric; its behavior varies based on ceramic composition.
Diode: Semiconductor acting as a one-way switch for current, facilitating flow in one direction while blocking the opposite.
Transistor: Miniature semiconductor managing current/voltage flow, amplifying signals, and functioning as a switch.
Voltage Regulator: Integrated circuit that maintains a constant output voltage despite load or input changes, typically focusing on linear regulation.
Integrated Circuit (IC): Small electronic device combining various components (transistors, resistors, capacitors) on a silicon chip.
7 Segment LED Display: Digital module displaying numbers with arranged LEDs for visibility.
Relay: Electrically operated switch, featuring input for control signals and output contacts for operations.

Embedded Systems

An embedded system is a dedicated computing unit designed to perform specific functions within a larger device.
Originating in the latter half of the 20th century, the earliest example was the Apollo guidance computer (1960).
The first commercially available embedded system was the Intel 4004, released in 1971.

Components of Embedded Systems

Hardware: Comprises physical components, including:
- Power Supply: Battery or external source.
- Processor: Manages electrical/mechanical tasks.
- Memory: Stores instructions for operation.
- Timers: Monitors time intervals or durations.
- Communication Ports: Facilitate interactions between systems (e.g., UART, USB, Ethernet).
Software: Includes:
- Assembly Language: Low-level representation of machine code instructions, allowing for ease of programming compared to binary code.
- Emulators: Simulate embedded systems on standard computers for debugging purposes.
- Debugger: Tool for monitoring and controlling code execution on embedded hardware, identifying and fixing issues.
- Compiler: Converts high-level programming code into machine code or assembly for execution on processors.

Characteristics of Embedded Systems

Self-Functioned: Operates independently, performing tasks without external intervention.
Tightly Constrained: Operates under strict limitations in processing power, memory, storage, and energy.
Real-Time: Designed to handle tasks or respond to events promptly within specific time constraints.
