A team of artists, scientists and engineers has developed a robotic lab assistant based on a modified 3D printer that can intelligently automate and adapt laboratory processes. By eliminating repetition and errors, aBioBot’s mission is to free up scientists’ energy and resources, potentially shortening the time between major scientific breakthroughs.

If life were like a movie, police stakeouts would only last a few minutes, cross-country travel would happen in seconds, and scientific discoveries would occur quite regularly, marked by a man in a lab coat shrieking “Eureka!” Unlike the movies, real life requires patience. Yet in the field of science, slow progress caused by tedious lab techniques isn’t just annoying, it may actually delay scientific discoveries that could benefit mankind.

According to San Francisco-based biotech startup aBioBot, one possible reason for this is the process of pipetting, wherein liquid chemicals, drugs, or biological matter are measured, transported and dispensed using small, vacuum-creating droppers.

Though considered a standard procedure in wet labs, it has significant shortcomings: “[Pipetting is] slow, boring, and causes repetitive strain injuries,” explains aBioBot. Moreover, it is often bad at delivering reproducible results that scale. “Pipetting wastes precious bio lab talent and time.”

The answer? To intelligently automate pipetting procedures, freeing up scientists to focus on, well, science, using a modified 3D printer and open source software.

“We are building a flexible and friendly robotic lab assistant to help scientists be scientists,” explained Dr. Raghu Machiraju, founder, CEO and primary software architect at aBioBot.

Machiraju is a Professor at the Ohio State University in the department of Computer Science and Engineering. He is also involved in the field of bioinformatics and cancer research, meaning has no doubt spent countless hours in a wet laboratory, frustrated at the inaccuracy of a pipetting experiment gone wrong.

The idea behind aBioBot comes from his real-world experiences, as well as a passion for ‘dabbling’ in new technologies, including 3D printing.  The liquid handling robotic platform he helped to design is, in fact, based on open source 3D printer hardware.

Using a series of custom adapters, the Bot allows scientists to use standard lab equipment, including common pipettes and well plates, while taking over the manual process. As aBioBot points out, Robots are great at doing boring things, like washing dishes and vacuuming—so why not let them do what already they do best?

While aBioBot is not the first company attempting to automate lab processes, what makes their machine unique is its sensing capabilities. Unlike other liquid handling robots, which could accidently drop a pipette yet to work unknowingly, aBioBot can ‘see’ and react thanks to Yan, it’s machine vision eyes.

“Yan is machine vision that watches over the experiment for you,” explains the company. Advanced sensors learn the layout of the bench’s objects, including wells, and can detect if something has been dropped or is being obstructed. Not only does this make the work more efficient, but also safer and less error-prone.

Another unique feature of aBioBot’s solution is called LabBench, which is a web browser interface that makes the entire pipetting process even easier. LabBench facilitates protocol authoring, monitors progress, and automatically records all records onto the LabCloud.

So far, the aBioBot has managed to port its APIs onto three different 3D printer-based hardware platforms. It has also been collaborating with an open-robotics company to provide software. “Although aBioBot is built on open source hardware and software, both Lab Bench and Yan will be accessible through open APIs and extended as necessary,” they explained.

While we’re not at the level of being able to fast-forward tedious and time-consuming tasks à la movie montage, aBioBot is a promising adaptive and flexible robotic assistant that could help bio-scientists speed up their work, and therefore their discoveries.

Currently, the company is working with early adopters to potentially develop protein assays for automation and improve on the 3D-printer based prototype Bots. aBioBot was funded in early 2015 by IndieBio’s startup incubator. Along with Machiraju, the company consists of hardware architect Ken Rinaldo, biologist Kun Huang, programmer Chaitanya Kulkarni and designer Trademark Gunderson.
