Robotics

An actuator is a component of a machine that is responsible for moving and controlling a mechanism or system. It converts energy (electrical, hydraulic, or pneumatic) into mechanical force or motion.

The simulation of human intelligence processes by machines, especially computer systems. These processes include learning, reasoning, problem-solving, perception, and decision-making, enabling machines to perform tasks typically requiring human cognition.

An autonomous robot is capable of performing tasks and making decisions without continuous human intervention. It can perceive its environment, navigate, plan, and execute actions independently, often adapting to changing conditions.

Closed-loop control is a control system that uses feedback from the system's output to adjust its input. It continuously monitors the actual performance, compares it to the desired state, and makes corrections to minimize errors and achieve accuracy.

A collaborative robot (cobot) is a robot designed to safely and directly interact with humans in a shared workspace. Unlike traditional industrial robots, cobots often have safety features, force sensing, and intuitive programming for human collaboration.

Computer Vision enables robots to 'see' and interpret images or video from their environment. It involves processing visual data to identify objects, recognize patterns, and understand spatial relationships, crucial for navigation, manipulation, and inspection tasks.

A robot controller is the brain of the robot, responsible for executing programs, processing sensor data, and sending commands to actuators. It manages the robot's movements, sequences, and interactions with its environment.

Degrees of Freedom (DoF) refer to the number of independent parameters that define the configuration or position of a mechanical system in space. For a robot, it typically corresponds to the number of joints or axes that can move independently.

Dynamics in robotics is the study of motion and the forces that cause it. It analyzes the relationship between forces, torques, mass, and acceleration, essential for understanding how a robot moves, interacts with its environment, and handles loads.

An end-effector is the device at the end of a robotic arm, designed to interact with the environment. It is the tool that performs the robot's specific task, such as grasping, welding, painting, or inspecting.

Feedback control is a control system where the output of the system is measured and compared to a desired setpoint. The difference (error) is then used to adjust the input, allowing the system to correct itself and maintain desired performance.

Forward Kinematics is the process of calculating the position and orientation of a robot's end-effector given the joint angles or positions of all its links. It determines where the robot's tool is in space for a given set of joint values.

A gripper is a type of end-effector used by a robot to grasp and manipulate objects. They come in various forms, such as two-finger, multi-finger, vacuum, or magnetic, designed for specific object shapes, sizes, and materials.

Haptics in robotics refers to the technology of creating a sense of touch and force feedback for human operators. It allows users to feel and manipulate virtual or remote objects, enhancing immersion and precision in teleoperation or training simulations.

Human-Robot Interaction (HRI) is the study of how humans and robots can effectively communicate and interact. It encompasses the design of interfaces, interaction modalities, and social factors to enable seamless and intuitive collaboration between them.

An industrial robot is an automatically controlled, reprogrammable, multi-purpose manipulator programmable in three or more axes. It is designed to perform tasks in manufacturing environments, such as welding, assembly, material handling, or painting.

Inverse Kinematics is the process of calculating the required joint angles or positions for a robot's arm to reach a desired position and orientation of its end-effector. It's a more complex problem than forward kinematics, often having multiple solutions.

The Jacobian Matrix in robotics relates the joint velocities of a robot to the linear and angular velocities of its end-effector. It's crucial for understanding differential kinematics, force/torque mapping, and singularity analysis in robot control.

Kinematics in robotics is the study of motion without considering the forces that cause it. It focuses on the geometric relationships between the links and joints of a robot, determining its position and orientation in space.

Localization is the process by which a mobile robot determines its own position and orientation within its environment. It uses sensors like GPS, LiDAR, cameras, or odometry to build or update a map and pinpoint its precise location.

A subset of Artificial Intelligence that enables systems to learn from data, identify patterns, and make decisions with minimal human intervention. It uses various algorithms to process data and improve performance over time, without explicit programming.

A manipulator is the arm-like mechanism of a robot, typically consisting of a series of links connected by joints, allowing for movement and positioning of an end-effector. It provides the robot's reach and dexterity.

Mapping in robotics is the creation of a spatial representation or map of an unknown environment. Simultaneous Localization and Mapping (SLAM) is a technique where a robot builds a map of its surroundings while simultaneously determining its own location within that map.

A mobile robot is an autonomous robot capable of moving in its environment and is not fixed to one physical location. They use wheels, tracks, or legs for locomotion and are often used for exploration, delivery, or surveillance.

Navigation in robotics is the ability of a robot to move from one location to another in an environment without human intervention. It integrates localization, mapping, and path planning to safely and efficiently reach its destination.

Open-loop control is a control system where the control action is independent of the system's output. The controller sends commands without measuring the actual outcome, assuming the system will perform as intended without any error correction.

Path planning is the process of finding a safe and optimal path for a robot to move from a starting point to a target destination, avoiding obstacles. It considers kinematic constraints, dynamic limitations, and environmental factors.

A machine capable of carrying out a complex series of actions automatically, especially one programmable by a computer. Robots can perform tasks autonomously or semi-autonomously, often interacting with their environment.

Robot ethics is a field that studies the moral considerations and societal implications of robots and artificial intelligence. It addresses questions of responsibility, safety, privacy, bias, and the impact of automation on human labor and society.

Robot Operating System (ROS) is a flexible framework for writing robot software. It is a collection of tools, libraries, and conventions that aim to simplify the task of creating complex and robust robot behaviors across diverse hardware platforms.

Robot programming involves creating instructions or code that dictates a robot's behavior, movements, and tasks. This can range from teaching by demonstration to writing complex algorithms in specialized languages or graphical interfaces.

Robotics is the interdisciplinary branch of engineering and science that deals with the design, construction, operation, and application of robots. It integrates fields like mechanical engineering, computer science, and artificial intelligence.

A sensor is a device that detects and responds to some type of input from the physical environment. It converts physical phenomena (e.g., light, heat, pressure) into electrical signals that a robot's controller can interpret.

Teleoperation is the control of a robot or machine from a distance by a human operator. The operator uses an interface to send commands, and the robot provides feedback (visual, haptic) to give the operator a sense of presence in the remote environment.

The workspace of a robot refers to the total volume of space that its end-effector can reach. It defines the physical operational limits of the robot, determined by its kinematic structure, joint limits, and link lengths.
