English articles about physical ai companies at Physical AI Lab.
GelSight Mini is a commercial optical tactile sensor, DIGIT is an open design, and Digit 360 is a newer multimodal research platform—not three simple performance tiers.
mmWave radar can add independent range and radial velocity in darkness, glare or airborne obscurants, but it does not replace camera semantics or LiDAR geometry by itself.
Google does not currently own Boston Dynamics. Google DeepMind is an AI partner working on Atlas foundation-model research and selected Gemini Robotics uses with Spot and Orbit.
Simulation fidelity is not one universal score. Test the subsystems that can change the target task using the same fixtures, inputs and metrics in simulation and hardware.
An open-data label does not automatically permit commercial use or redistribution. Review dataset terms, code, people, locations and third-party material as separate rights layers.
Robot red teaming is not permission to attack a live system. It is defensive validation with written authorization, containment, reduced-energy progression, stop conditions, evidence and remediation retests.
The cheaper option is not revealed by subscription price versus robot price. Put integration, downtime, utilization, overages and residual value on the same time horizon.
An exported checkpoint is not a deployable robot policy. Treat input contracts, dynamic shapes, end-to-end latency, numerical parity, closed-loop safety and rollback as one release gate.
A remotely supported home robot is both a moving sensor and an actuator. Use it only after the household understands who can connect, what they can see or move, how access is shown and logged, and how data is deleted.
A hand-eye calibration is trustworthy only when frame directions are explicit, the pose set contains independent rotations, and the result survives unseen poses and real task-space measurements.
