Synthetic Data For Robotics

Definition and Core Concepts

Synthetic data refers to artificially generated data that mimics real-world information. In the context of robotics, synthetic data is created using computer simulations, algorithms, or generative models to replicate the types of data robots encounter in their operational environments. This data can include images, sensor readings, motion trajectories, and environmental variables, all tailored to specific use cases.

The core concept behind synthetic data is its ability to simulate diverse scenarios that may be difficult or impossible to capture in real life. For example, synthetic data can model extreme weather conditions, rare events, or hazardous environments, providing robotics systems with the training they need to perform reliably under various circumstances.
