Researchers at the University of Toronto have developed a robotic system named Organa, which can automate various chemistry lab tasks. Led by Alán Aspuru-Guzik, a chemist and computer scientist, the team created Organa to handle experiments traditionally done by humans, such as pipetting samples, running analyses, and generating reports. Organa uses computer vision and a large language model (LLM) to translate verbal instructions into an experimental process. This enables scientists to communicate with the robot naturally, allowing it to perform complex, multistep experiments and provide feedback during the process.
Organa stands out from other automated systems by being flexible and customizable. It can handle an entire experiment rather than just one part, and scientists don't need to know how to program it—Organa can understand their spoken instructions and convert them into steps it can follow. The system can even troubleshoot when there are ambiguous instructions or unexpected outcomes. A key benefit is that Organa’s hardware is largely made from off-the-shelf parts, making it easier for other labs to replicate.
Organa’s first major test involved characterizing the electrochemical properties of quinones, a compound used in rechargeable batteries. The robot completed the 19-step process with results comparable to those of a human scientist. Although it didn’t outperform humans in speed, its ability to work continuously offers a significant productivity advantage. Additionally, Organa can analyse data, identifying outliers and suggesting ways to address uncertainties.
This innovation could save researchers time and effort on repetitive tasks, allowing them to focus on more complex scientific problems. The team continues to refine Organa’s capabilities, aiming to make it even more adept at handling experimental challenges.
