Glossary of Terms

D​

Digital Twin​

A virtual representation of a physical robot system that mirrors its real-world counterpart for simulation, testing, and analysis.

Dynamic Behavior​

The way objects move and interact in response to forces and constraints in a physics simulation environment.

G​

Gazebo​

A robotics simulator that provides accurate physics simulation and realistic rendering for robot development and testing.

H​

High-Fidelity Visualization​

The rendering of realistic visual environments that closely match real-world appearance and lighting conditions.

I​

IMU (Inertial Measurement Unit)​

A sensor that measures specific force, angular rate, and sometimes the magnetic field surrounding the body using accelerometers, gyroscopes, and magnetometers.

L​

LiDAR (Light Detection and Ranging)​

A remote sensing method that uses light in the form of a pulsed laser to measure distances and create 3D representations of the environment.

P​

Physics Simulation​

The computational modeling of physical laws and interactions in a virtual environment to create realistic robot-world interactions.

S​

Sensor Simulation​

The computational modeling of sensor outputs that replicate real sensor behavior in virtual environments.

U​

Unity​

A real-time 3D development platform used for creating high-fidelity visualizations and interactive experiences for digital twins.
