Robotics Industry Glossary
E
Edge AI
Running inference and lightweight training directly on robot hardware to minimize latency, bandwidth, and cloud dependency.
Edge Computing
Processing data locally on or near the robot rather than in a remote cloud, enabling low-latency real-time decision-making.
Edge Computing in Robotics
Processing data on the robot (“at the edge”) rather than in the cloud, reducing latency for time-critical decisions.
Educational Robot
A robot designed to teach programming, engineering, and STEM concepts to students at various levels.
EKF (Extended Kalman Filter)
A nonlinear state estimation algorithm used in robotics for sensor fusion, localization, and SLAM.
Elastic Actuator
An actuator with an intentionally compliant (spring-like) element, providing shock absorption and energy storage.
Embedded System
A dedicated computer system within a robot that performs specific control tasks, often running real-time operating systems (RTOS).
Embodied AI
AI research focusing on agents (robots) that learn through interaction with a physical environment, not just data.
Emergency Off
A hardware-level safety circuit that removes power from robot actuators in an emergency, more severe than an E-Stop.
Emergency Stop (E-Stop)
A hardware-level safety circuit that immediately cuts power to actuators when triggered, independent of software control loops.
Encoder
A sensor that converts rotary or linear motion into electrical signals, providing position and velocity feedback for robot joints.
End-effector
The device at the end of a robotic arm designed to interact with the environment such as a robotic gripper, welder, or camera).
End-of-Arm Tooling (EOAT)
See End-Effector. Also includes mounting plates, tool changers, and sensors attached at the robot’s wrist.
Energy Harvesting
Technologies that capture ambient energy (solar, vibration, thermal) to power small robots and extend mission duration.
Envelop (Work Envelope)
The complete volume of space that a robot’s end-effector can reach, defined by its mechanical structure and joint limits.
EOD Robot
A bomb disposal (Explosive Ordnance Disposal) robot used by military and law enforcement to remotely inspect and neutralize threats.
Epipolar Geometry
The geometric relationship between two camera views used in stereo vision to compute depth information.
Ergonomics
The study of designing robot workstations and interfaces to optimize human comfort, safety, and productivity.
EtherCAT
A high-performance industrial Ethernet protocol widely used for real-time communication between robot controllers and drives.
Ethical Ai
The practice of designing, developing, and deploying AI systems that are fair, transparent, and beneficial.
Euclidean Distance
The straight-line distance between two points in space, a fundamental calculation in robot navigation and path planning.
Exoskeleton
A wearable robotic device that augments human strength, endurance, or rehabilitation by assisting limb movement.
Explainable AI (XAI)
Making AI/robotic decision-making transparent and understandable to humans, crucial for trust in autonomous systems.
Exploration (Robot)
The process by which an autonomous robot discovers and maps unknown environments using sensors and planning algorithms.
Exteroceptive Sensor
A sensor that measures the external environment, such as cameras, LiDAR, ultrasonic sensors, and infrared sensors.
