WetRobo: A Reproducible Robot Kit Lets Coding Agents Run Real Wet-Lab Experiments
sherryyangML · x · 2026-09-19
Sherry Yang and collaborators released WetRobo (arXiv:2609.18435), a reproducible robot kit where a coding agent observes a wet lab, writes and executes robot programs, and adapts via physical trial and error.
- The kit bundles a robot arm, lab equipment (incubator, capped reagent bottle, Petri dish), recorded teleoperation demos, and a general skill file, designed to transfer between laboratories
- Biologists give natural-language tasks with no local teleop data collection or neural-net training
- Using OpenAI Codex (gpt-5.6-sol), the agent completed three real-world tasks in two labs: lifting a Petri dish lid, removing a bottle cap, opening an incubator door
- A VLA fine-tuned on Lab X demos failed to transfer to Lab Y, while the coding agent succeeded in both
The authors argue academia's edge over fast-improving generalist robot systems is robots doing real science in physical labs.
