Key Concepts in Robotics

Definition of a Robot

A robot is a programmable machine capable of carrying out a complex series of actions automatically. Robots can be autonomous, semi-autonomous, or manually operated, and they are designed to perform specific tasks across various environments.

Components of a Robot

  1. Sensors:Detect environmental conditions and internal states to provide data for decision-making.
    • Examples:Cameras, ultrasonic sensors, LIDAR, accelerometers, and gyroscopes.
  2. Actuators:Convert electrical signals into physical movement.
    • Examples:Motors, servos, and hydraulic or pneumatic systems.
  3. Control System:The brain of the robot, which processes input from sensors and sends commands to actuators.
    • Types:Centralized or distributed control systems, often powered by microcontrollers or computers.
  4. Power Supply:Provides energy to the robot’s components.
    • Examples:Batteries, solar panels, or wired power sources.
  5. End Effectors:Tools or devices attached to the robot to interact with the environment.
    • Examples:Grippers, welders, or surgical instruments.

Types of Robots

  1. Industrial Robots:
    • Application:Used in manufacturing for tasks like welding, painting, assembly, and material handling.
    • Designs:Articulated arms, SCARA, delta robots, and cartesian robots.
  2. Service Robots:
    • Application:Perform services for humans, such as cleaning, delivery, or healthcare assistance.
    • Examples:Robotic vacuums, autonomous delivery robots, and robotic exoskeletons.
  3. Humanoid Robots:
    • Application:Designed to mimic human form and behavior for interaction and assistance.
    • Examples:ASIMO, Sophia, and Pepper.
  4. Mobile Robots:
    • Application:Move through various environments for tasks like exploration, surveillance, and mapping.
    • Examples:Drones, autonomous vehicles, and robotic rovers.
  5. Collaborative Robots (Cobots):
    • Application:Designed to work safely alongside humans in shared environments.
    • Examples:Baxter, UR3, and LBR iiwa.
