PoLARIS Project: Laboratories of the Future 🌐​

The Laboratory for Artificial Intelligence, Robotics, Informatics, and Standards for Polymers (PoLARIS) Project aims to combine polymer science with robots and artificial intelligence to conduct autonomous experiments remotely, via a new cloud infrastructure.

This ambitious project is funded by a $20 million grant from the U.S. National Science Foundation (NSF). It is being implemented through a collaborative effort between the University of Chicago Pritzker School of Molecular Engineering (UChicago PME), the University of Chicago Department of Computer Science, and Argonne National Laboratory.

According to UChicago PME, PoLARIS aims to strengthen local supply chains, reduce reliance on foreign materials, and help American companies lead in global competition in sectors exceeding $200 billion annually.

AI as the Brain, Robots as the Hands: An Interview with Jie Xu 🧠✋​

Jie Xu, one of the project leaders, answered questions from Automation World. Xu explained his role in PoLARIS and the project's goals as follows:

• Role: Assistant Professor at the UChicago Pritzker School of Molecular Engineering and co-principal investigator of PoLARIS. He leads one of the hardware infrastructures and scientific drivers. He integrates robotic platforms, instruments, and experimental workflows.
  
• Project Description: PoLARIS is a cloud laboratory for polymers and soft materials. It brings together materials science, artificial intelligence, robotics, automation, and advanced characterization. Its purpose is to enable researchers to conduct complex experiments remotely and to make materials research faster, more reproducible, and accessible to a wider community.
  

Collaboration of AI and Robots 🤝​

Xu explains how robots and artificial intelligence work in soft material and polymer science:

“I see robots as the hands and eyes, AI as part of the brain, and scientists as providing the scientific intent and judgment.”

• Robots: Perform physical tasks such as dispensing chemicals, conducting reactions, making films, transferring samples, and taking measurements.
  
• Artificial Intelligence: Decides which experiments should be performed, plans experiments, analyzes incoming data, identifies trends or uncertainties, and suggests the next step.
  
• Software Infrastructure: Connects these parts to work as a single workflow.
  

Scientists can supervise the process, impose constraints, and intervene with their expertise when needed. This human-AI partnership is central to their understanding of autonomy.

AI and Robotics in Autonomous Experiments 🔄​

According to Xu, the core idea is to close the experimental loop:

“Normally, a researcher performs an experiment, analyzes the results, decides what to try next, and then goes back to the lab. In an autonomous workflow, many of these steps can happen continuously. The robotic system performs the experiment and collects the data, the model analyzes the results and suggests the next conditions, and the system starts the next round. This way, research can progress much faster.”

PoLARIS will expand this type of workflow, already demonstrated with Polybot, the AI-driven robotic laboratory at the Center for Nanoscale Materials at Argonne.

Future Experiments and Industrial Impact 🚀​

Regarding how PoLARIS will affect the use of AI in experiments, Xu states:

“The broader impact of PoLARIS on soft materials research and engineering could be to move AI from primarily a data analysis tool to an active partner in experiments and scientific decision-making processes.”

AI can translate scientific goals into experimental workflows, select promising experiments, respond to unexpected results, integrate diverse data sources, and continuously improve its models as experiments progress.

This approach has the potential to transform many industries that need to navigate broad design spaces covering chemistry, formulation, and processing conditions, including coatings, electronics, batteries, packaging, and advanced manufacturing.

Example: Electrochromic Materials 🌈​

As an example of how AI, robotics, and data infrastructure combine in a remotely accessible cloud laboratory, he points to electrochromic materials:

A researcher might be looking for an electrochromic polymer with a specific color and/or optical switching behavior. They can define their target through PoLARIS. An automated synthesis platform can prepare candidate polymers, another platform can make thin films, and these films can be electrochemically and optically tested. Experimental data is collected into the same infrastructure, and the model can use these results to suggest the next compositions or processing conditions.

Supply Chains and Global Competition 🌍​

Regarding how PoLARIS will strengthen local supply chains and help U.S. companies in global competition, Xu says:

“Developing a new material can take a long time because companies often have to try many combinations of chemistry, formulation, processing, and testing before they find something reliable. PoLARIS can help shorten this process. Companies can use shared automated facilities to test more possibilities, reduce R&D risk, and generate consistent data without having to build and operate all this infrastructure themselves.”

The Future and Excitement of the Project ✨​

What excites Jie Xu most about the project is that this concept has existed for a long time, and now a great team has come together to build it and make it a reality. Making PoLARIS work for ambitious science will be very exciting. We have already seen what AI and automation can do for real materials problems through Polybot. PoLARIS offers an opportunity to take this much further.
