## Foundation Models in Robotics

Robotics foundation models have made significant progress in following natural language instructions to pick, place, and manipulate various objects. However, as these models become more capable, evaluating them rigorously has become increasingly challenging.

## Challenges of Real-World Testing

Testing in the real world is expensive, slow, and difficult to reproduce. Therefore, simulations are used to evaluate robot performance. However, existing simulations have some critical issues.

## Visual Domain Overlap

The data and environments used for policy training and evaluation often come from the same visual source. This shows that the model has memorized the setup but does not measure its ability to generalize in the real world.

## Benchmark Saturation

Most benchmarks have a fixed task set that is rarely updated. This leads to models quickly reaching maximum scores, making it difficult to distinguish which model is genuinely more capable.

## Diagnostic Gap

A binary success/failure score does not explain why a robot failed. Was it confused by the object's color, instruction phrasing, or a shifted camera? Without answers to these questions, researchers have little to act on.

## Statistical Trustworthiness

Every physics engine and policy is subject to some stochasticity. A small sample success rate does not provide reliable information about a policy's true performance.

## Clopper-Pearson Method

The Clopper-Pearson method is used to construct a binomial confidence interval around the success rate. This method allows for a statistically reliable evaluation of policy performance.

## RoboLab Platform

RoboLab is a simulation platform developed to evaluate robot performance. It offers robot-agnostic evaluations, rapid task generation, and comprehensive analysis tools.

## Rapid Task Generation

RoboLab enables the rapid generation of new tasks. This prevents benchmark saturation and allows models to continuously improve.

## Comprehensive Analysis Tools

RoboLab provides a suite of analysis tools that show how well a policy is performing, when it fails, and why it fails.

## Agentic AI Support

RoboLab supports agentic AI workflows, allowing users to generate new tasks directly. This ensures the benchmark is future-proof.

## Conclusion and Importance

RoboLab is a significant step in evaluating how robot policies will perform in the real world. This platform enables researchers to obtain more reliable and meaningful results.
