A universal platform for humanoid robot teleoperation and data collection, compatible with leading humanoid robots. Walk naturally in any direction with a VR omnidirectional treadmill, powered by ultra-low-latency first-person control. By KAT PRO

Physical AI is making a classic Moneyball error by mis-pricing data. Optimizing for "cumulative operational hours" or relying on low-variance production telemetry is the robotics equivalent of chasing batting averages, when we should be isolating on-base percentage. Unlike text, every useful hour of robot data is paid for. If you aren't calculating marginal utility per dollar based on data novelty and intrinsic dimensionality, you're allocating capital based on vibes. In physical AI, useful data is strictly resource-constrained, shifting the goal from maximizing compute efficiency to maximizing marginal loss reduction per dollar. A framework breaking down: - Interventional vs. Observational channels - Why deployment telemetry behaves like a decaying oil well - The "Convergence Trap" of narrow commercial niches - Metrics to replace raw operational hours check out the full post here: open.substack.com/pub/praxiscurr…
