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.
