Behind every moving gear, glowing sensor, and decision-making algorithm lies a foundation of essential knowledge — the Core Principles and Terminology of robotics. This section of Robot Streets is your backstage pass into the language, physics, and logic that bring intelligent machines to life. From torque and tension to servos and sensors, this hub breaks down the scientific DNA of robotics in ways that are approachable, visual, and endlessly fascinating. You’ll explore the rules that govern motion, power, and perception — plus the technical terms that engineers use to describe the art of building smarter, faster, more adaptive robots. Whether you’re a curious beginner or a maker fine-tuning your next creation, these articles help you decode robotics from the inside out. Think of it as your translator between concept and creation — the spark that turns curiosity into capability. Welcome to the fundamentals that power every robot on the street, in the lab, and beyond.
A: Open-loop sends commands blindly; closed-loop uses feedback (encoders/IMU) to correct.
A: Servos = position control; steppers = precise steps; DC = simple speed + encoder for position.
A: Inertial Measurement Unit—gyro + accel (+/- magnetometer) for orientation/motion.
A: Brownout from inrush; add bulk capacitance, separate supplies, and proper grounding.
A: Switches current through a DC motor to go forward, reverse, or brake.
A: Forward: joints → pose; Inverse: desired pose → joint angles.
A: Building a map while figuring out where you are inside it.
A: Yes—start with P, add D to calm overshoot, then I to kill steady-state error.
A: To safely connect 5V and 3.3V logic without damaging pins.
A: Use RC filters or software debounce/timers to ignore rapid repeats.

What Are Sensors in Robotics? Types and Uses
Sensors are the eyes, ears, and nerves of modern robots. From LIDAR mapping and vision systems to tactile feedback and motion tracking, discover how sensing technology powers intelligent automation and real-world robotics innovation.

The Difference Between Robots, AI, and Automation
Robots move. AI thinks. Automation streamlines. Together they power the modern world—but they’re not the same. Discover how these technologies differ, where they overlap, and why understanding each one is essential for entrepreneurs, engineers, and innovators building the future.

Robot vs Automation: What’s the Difference?
Robots and automation are often confused—but they’re not the same. Discover how robots act as machines while automation orchestrates entire systems, and learn how both technologies power modern manufacturing, logistics, healthcare, and digital business. This in-depth guide breaks down the differences and shows how they work together to shape the future.

The Core Principles of Robotics Everyone Should Know
Robots shape modern life in ways most people never notice. From sensors and motion to autonomy and safety, these core robotics principles reveal how machines perceive, decide, and act in the real world—and why they’re transforming everything from factories to homes.

Robotics Terminology Explained: A Plain-English Guide
Robotics doesn’t have to sound complicated. This plain-English guide breaks down common robotics terms so anyone can understand how robots sense, move, and make decisions in the real world.
