Understanding Machine Learning Interatomic Potentials in Chemistry and Materials Science

Image
Machine learning interatomic potentials (MLIPs) sit in a sweet spot between classical force fields and expensive quantum chemistry. They learn an approximation of the potential energy surface from reference calculations (often density functional theory or higher-level methods), then use that learned mapping to run molecular dynamics and materials simulations far faster than direct quantum calculations—while keeping much more chemical realism than many traditional empirical potentials. That speed-up changes what scientists can attempt: longer time scales, larger systems, broader screening campaigns, and faster iteration between hypothesis and simulation. But MLIPs also introduce new failure modes: silent extrapolation, dataset bias, uncertain reproducibility, and “it looks right” results that may not hold outside the training domain. This page explains MLIPs in a practical way—how they work, which families exist, how to build them responsibly, and how to trust (or distrust...

Ensuring Data Privacy in Physics-Based Robot Simulation Workflows

Image
Physics-based robot simulation can generate a surprising amount of data: camera frames, lidar-like point clouds, control commands, collision events, trajectory traces, scenario metadata, and full “replay” logs. That data is incredibly useful for training and validation—but it can also leak proprietary design details and, in some workflows, personal or sensitive information (for example, when simulations use real facility maps, human recordings, or logs collected from deployed robots). Disclaimer: This article is for general information only and is not legal, compliance, or security advice. Data privacy requirements vary by country, industry, and contract. If you handle personal data or safety-critical systems, consult qualified privacy/security professionals and follow your organization’s policies. Tools, standards, and regulations can change over time. TL;DR Simulation data can expose IP (CAD/meshes, controller logic, scenario libraries) and sometimes per...

Advancing Generalist Robot Policy Evaluation Through Scalable Simulation Platforms

Ethical Considerations of Robots Learning from Single Demonstrations

Image
Note: Informational only, not legal or safety advice. Real-world robots can behave unexpectedly; always test carefully, keep humans in control, and follow applicable safety guidance. Policies and best practices can change over time. Robots capable of learning tasks from a single demonstration have advanced through training in simulated environments. The appeal is obvious: instead of engineering every behavior by hand, a robot can watch once, generalize, and act. In practice, that “watch once” moment is supported by extensive prior training—often in simulation—so the robot has already learned useful building blocks (grasping, moving, aligning, timing) before it ever sees your specific task. In May 2017, discussions about safe autonomy often returned to a simple philosophical benchmark: Isaac Asimov’s “Three Laws of Robotics” . They are not a technical specification, but they are a useful checklist for what society expects from machines: prevent harm to people, follow hu...
