Simplot

Simplot (Action Reasoner) turns plain English into validated action lines that drive NVIDIA Isaac Sim live. Instead of an LLM that narrates, we fine-tuned Meta's Muse-Glimmer-30B (QLoRA) on 470 machine-validated traces so it thinks in l ogic actions: every reply is executable, catalog-checked commands like create.objects.cuboid or robot.set.joint_drive. A Thinker plans, a reflex fast-path answers primitives with no LLM call, and an 18-agent dispatcher (sensing, physics, na vigation, manipulation…) decomposes multi-skill jobs with an xval QA gate. Execution runs through an in-sim extension pl us a file bridge, with a sense watchdog streaming stage events back as text. Proven live: an end-to-end DWA rover drive to goal, plus a safety net (math preflight, failure black-box, emission gate, proof-replay driver). The problem: robot-s im work today is manual GUI clicking or brittle scripts. Simplot makes it conversational, reproducible, and verifiable — 267/267 offline tests green.
