The work of chemists permeates almost every aspect of modern life, from engineering life-saving vaccines and medicines to supporting industry, agriculture, material science and the energy sector.

Given the importance of their work, it’s a little surprising that in an age of automation, some of the most time-consuming tasks chemists perform are accomplished much as they were a century ago: Lab processes are often manual and repetitive, and they frequently require a great deal of low-level task monitoring. Efforts to change this have been limited, primarily because chemistry labs are such high-risk environments—toxic chemical exposure, fires and explosions lead to tens of thousands of injuries each year.

However, a team of researchers at ��ϳԹ� was recently awarded $1.8 million by the National Science Foundation for a project, titled "Human-Robot Collaboration for the Future of Organic Synthesis," to help change this. Led by Carson Bruns, assistant professor of mechanical engineering with the ATLAS Institute, the team aims to shift some of the most time-consuming tasks to robots by developing new, open-source robot software and innovative hardware designs.

“Our goal is to develop technology that can be the hands of the chemists,” says Bruns, “freeing them up so they can do the hard cognitive work that only people can do.” Advances in robotic chemistry assistants could help transform synthetic chemistry worldwide, accelerating progress in critical fields like biomedicine, material science, and energy production and storage.

Divided over four years, the award falls under the Future of Work at the Human-Technology Frontier, an NSF initiative focused on augmenting human performance by developing more sophisticated human-technology partnerships. Bruns’ principal CU-based collaborator is Alessandro Roncone, assistant professor of computer science at ��ϳԹ�. A third partner on the project is Dan Szafir. A colleague of Bruns’ at the ATLAS Institute until Spring 2021, Szafir is now an assistant professor of computer science with the University of North Carolina Chapel Hill, where his work will be supported with $600,000 of the total award amount.

This isn’t Bruns’s first foray into chemistry-related automation. For the last three years, a PhD candidate he advises, Kailey Shara, has been developing a lab robot that automates repetitive chemical reactions. Her latest prototype is able to heat, cool and stir precise quantities of wet and dry reagents—technology she's commercializing with the launch of a private company, Chembotix, which won awards from ��ϳԹ�’s New Venture Challenge (first place) and, in November 2022, Lab Venture Challenge.

Alessandro Roncone works with a student in his lab, the Human Interaction and Robotics Group.

Complementing Bruns’ knowledge in chemistry automation, Roncone brings critical skills to the project with expertise in human-robot interaction. Director of the Human Interaction and Robotics [HIRO] Group in the Department of Computer Science, Roncone specializes in developing robotic technologies that facilitate close, natural and extended cooperation with people.

However, designing a robot that can operate alongside people in cluttered and crowded spaces where dangerous chemicals are present, is no small challenge. Most mobile robots currently rely on visual cues for navigation, but when objects or people obscure lines of sight, visual information has limitations. To address this issue, Roncone plans to incorporate a flexible artificial skin on the robot that is equipped with accelerometers, along with proximity and pressure sensors. “For a robot to be effective in this context, its actions must build confidence and trust,” says Roncone. “It’s not enough that it never collides with anything or anyone; people must also feel comfortable and safe working alongside it.”

They will be adapting a sophisticated commercial robot that was purchased in 2019 with funds from a joint proposal submitted by Szafir and Bruns. While still at ATLAS, Szafir used the robot for several studies aimed at developing software to facilitate robot-human collaboration: One focused on improving a robot’s ability to select specific objects in a cluttered space based on verbal cues from a human. Another was aimed at helping robots recognize active group conversations that should not be interrupted. Szafir’s role will be to continue this work, shaping software to achieve the team’s objectives.

Final confirmation for the award came through from the NSF in September. It was a moment to celebrate to be sure, and also the moment when aspirations become a concrete challenge.

The team begins with a deep well of relevant experience and knowledge, and their work has the potential to accelerate chemistry research in many different fields. It will also have wide-ranging impacts on similar development in other fields—a robot that is able to move around a crowded chemistry lab, performing useful tasks while safely handling dangerous chemicals will be capable of many less challenging tasks.

Robots help build cars, fly planes, fight wars and provide healthcare; they play a role in countless industries, but for the most part, they don't work in chemistry labs. A team of ��ϳԹ� scientists plans to change that.
