WetRobo: Coding Agents Run Wet-Lab Experiments with Robot Arms

A team led by @YunaOikawa1, with collaborators from NYU, the University of Tokyo and others (including Lerrel Pinto), released WetRobo (arXiv:2609.18435), a reproducible kit that lets coding agents autonomously write programs, control a robot arm to perform wet-lab operations, and adapt through physical trial and error. Sherry Yang argues the project shows coding agents as an interface between foundation models and scientific instruments—physically executing experiments and adapting along the way, not just reasoning about them.

Confirmed

• The kit consists of a robot arm plus experiment-related components and is reproducible
• Cross-lab generalization test: a VLA policy trained on Lab X demonstrations scored 10/10 in Lab X but 0/10 in Lab Y; the code-adaptive agent system achieved 10/10 in both labs
• Deployment: robot hardware, demonstration data and an AGENTS.md are packaged and handed to a coding agent, which adapts at the new lab—no new teleoperation data or per-site policy retraining needed
• During adaptation the agent can call existing tools such as SAM for segmentation

Why it matters

• Cross-lab generalization failure (10/10 to 0/10) is a classic pain point in robot learning; WetRobo's "hardware + demos + docs package with on-site code adaptation" sidesteps per-site retraining and offers a new transferable-deployment paradigm
• Pushing coding agents from pure software tasks into physical experiment execution is a notable step toward connecting foundation models with scientific instruments
