Episode 98: Robotic chemists to discover new materials - Gabriella Pizzuto

What this episode covers

Gabriella Pizzuto, a Lecturer in Robotics and Chemistry Automation at the University of Liverpool, discusses deploying intelligent robotic manipulators to accelerate material discovery in chemistry labs. She explains how her team uses dual-arm mobile manipulators to handle powders, solvents, and glassware, aiming to run experiments around the clock while minimizing human exposure to chemicals. Pizzuto highlights the shift from pre-programmed open-loop systems to robot learning, where AI-driven methods like Bayesian optimization guide chemical reactions based on sensor feedback. She also notes that while data interpretation is easier, the physical challenge of making robots robust enough to handle non-standardized materials in semi-cluttered lab environments remains significant.
