As explained recently in the journal Science Robotics, robots are rapidly, “Transforming Science Labs into Automated Factories of Discovery.” In fact, laboratories across the disciplines of chemistry, biochemistry, and materials science are on the verge of a sweeping transformation as robotic automation and AI lead to faster and more precise experiments that unlock breakthroughs in fields including health, energy, and electronics.
According to the UNC-Chapel Hill researchers, today’s human-paced, trial-and-error approach is unnecessarily time-consuming and labor-intensive, slowing the pace of discovery. Automation offers a solution. Robotic systems can perform experiments continuously without human fatigue, significantly speeding up research. Robots not only execute precise experimental steps with greater consistency than humans, but they also reduce safety risks by handling hazardous substances.
By automating routine tasks, scientists can focus on higher-level research questions, paving the way for faster breakthroughs. Robotics has the potential to turn everyday science labs into automated ‘factories’ that accelerate discovery, but to do this, we need creative solutions to allow researchers and robots to collaborate in the same lab environment. With continued development, robotics and automation are expected to improve the speed, precision and reproducibility of experiments across diverse instruments and disciplines, generating the data that artificial intelligence systems can analyze to guide further experimentation.”
This research defined five levels of laboratory automation to illustrate how automation can evolve in science labs:
- Assistive Automation: At this level, individual tasks, such as liquid handling, are automated while humans handle the majority of the work.
- Partial Automation: At this level, robots perform multiple sequential steps, with humans responsible for setup and super vision.
- Conditional Automation: Here, robots manage entire experimental processes, though human intervention is required when unexpected events arise.
- High Automation: At this level, robots execute experiments independently, setting up equipment and reacting to unusual conditions autonomously.
- Full Automation: At this final stage, robots and AI systems operate with complete autonomy, including self-maintenance and safety management.
These levels of automation can be used to assess progress in the field, help in establishing appropriate safety protocols, and set goals for future research in both science domains and robotics. Although level 1, 2, & 3 automation is becoming increasingly common today, achieving high and full automation is a research challenge that will require robots capable of operating across different lab environments, handling complex tasks and interacting with humans and other automation systems seamlessly.
As the researchers emphasize, the full potential of automated laboratories will be realized only if artificial intelligence enables scientists to advance automation beyond physical tasks. AI can analyze vast datasets generated by experiments, identify patterns and suggest new compounds or research directions. Integrating AI into the laboratory workflow will allow labs to automate the entire research cycle — from designing experiments to synthesizing materials and analyzing results.
In AI-driven labs, the traditional Design-Make-Test-Analyze (or DMTA) loop can become fully autonomous. AI could deter mine which experiments to conduct, make real-time adjustments, and continuously improve the research process. While AI systems have shown early success in tasks like predicting chemical reactions and optimizing synthesis routes, the researchers caution that AI must be carefully monitored to avoid risks, such as the accidental creation of hazardous materials.
Transitioning to automated labs presents significant technical and logistical challenges. Laboratories differ widely in their setups, ranging from single-process labs to large, multiroom facilities. Developing flexible automation systems that work across diverse environments will require mobile robots capable of transporting items and performing tasks across multiple stations. Training scientists to work with advanced automation systems is equally important.
Researchers will not only need to develop expertise in their scientific fields but also understand the capabilities and limitations of robots, data science and AI to accelerate their research. Educating the next generation of scientists to collaborate with engineers and computer scientists will be essential for realizing the full potential of automated laboratories. This integration of robotics and AI is poised to revolutionize science labs. By automating routine tasks and accelerating experimentation, there is great potential for creating an environment where breakthroughs occur more quickly, safely, and at much lower cost, than ever before.
