The gap is real2sim
Sep 21, 2026
Every robotics team has a sim2real story. A policy that works in simulation, deployed on hardware, and something breaks. The grasp misses by a centimeter. The wheel slips on a floor that looked like every other floor. The camera sees a shadow the simulator never rendered. We call this the sim2real gap, and we measure it at the point where it shows up: deployment. But that is not where it starts. Most of the gap was already there before training began, baked into the simulated world the policy learned from. The simulator was wrong about the world, and the policy inherited the error. Sim2real is the symptom. Real2sim is the cause.

Real vs Simulated Robot Training Data
Aug 6, 2026
Every robotics team eventually has the same argument. Should you buy real data or generate it in simulation? This article explores which problems simulation solves well, where it falls short, and why understanding the difference matters when training robots.

Why Egocentric Data Is Not Enough
Aug 6, 2026
Egocentric video became the standard for robot training because it is affordable, easy to scale through people, and closely matches a robot's point of view, making it the preferred choice for collecting training data.
