We build real-world RL environments for robots. Starting with tasks from industry partners, we test policies on real robots and identify where they fail. We use those failures to decide what data to collect and curate for the next policy update. Next, we're setting up physical sandboxes at partner sites, so policies can train on the exact tasks and conditions they'll face in deployment.
