Study Notes

Robotics Overview

Robotics combines art and technology, focusing on the design, application, and use of robots across various industries.
Applications include manufacturing, space exploration, research, assistance for disabled individuals, military use, and entertainment.
Defined by ISO 8373 as an "automatically controlled, reprogrammable, multipurpose manipulator" with at least three axes.
The Robot Institute of America highlights robots as multifunctional manipulators for moving materials and tools through programmed motions.

Historical Context

Karel Čapek coined the term "robot" in his play Rossum’s Universal Robots, addressing themes of work automation by man-made beings.
"Robotnik" means peasant, and "robota" translates to drudgery or servitude in Czech.
Isaac Asimov introduced the "Three Laws of Robotics":
- Zeroth Law: Prevent harm to humanity.
- First Law: Prevent harm to individual humans unless in conflict with a higher law.
- Second Law: Obey humans, unless in conflict with higher laws.
- Third Law: Protect its own existence, unless in conflict with higher laws.

Advantages and Disadvantages of Robots

Advantages:
- Increased productivity, efficiency, and quality in various tasks.
- Ability to work in hazardous environments without human limitations.
- Continuous operation without fatigue or need for rest.
- High precision and capability to handle multiple tasks simultaneously.
Disadvantages:
- Economic impact on the workforce, leading to job displacement and retraining needs.
- Limited emergency response capabilities.
- Safety measures required to protect human workers.
- Lack of cognitive abilities compared to humans.

Robot Classification

Fixed-sequence robots: Perform tasks in a predetermined order, hard to modify.
Playback robots: Learn tasks from human operators and repeat recorded motions.
Numerical-control robots: Movements are programmed directly, rather than learned by demonstration.
Intelligent robots: Adapt to changing environments and complete tasks successfully.

Robotic Components

Effectors: Movable parts like arms and legs that enable action in the environment.
Perception: Sensors act as the robot's senses, collecting data about the surroundings.
Control: The computing system that directs robot functions and actions.
Communication: Mechanisms that allow robots to interact with humans and other systems.
Power: Supplies energy that enables all robotic functions.

Robot System Elements

Manipulator or rover: Main body structure composed of links and joints.
End effector: The robot's "hand" that interacts with external objects, equipped with tools like welding torches.
Actuators: Move the robot’s components under signals from the controller.
Sensors: Gather information for assessing the robot's position and surrounding environment.
Controller: Manages motions and system feedback, analogous to a brain's functionality.
Processor: Executes calculations for movements and oversees system coordination.
Software: Includes the operating system, robotic software for calculating motion, and application-specific routines for various tasks.
