Liquid Handling Robot systems oftentimes use peristaltic pumps to deliver reagents and other fluids to test sites. Although some smaller volumes of liquid can easily be delivered by plunger-style syringe pumps, larger liquid volumes often use peristaltic pumps because they have much higher displacement volumes and the mechanical system of rollers and motors are not exposed to the liquid itself. This paper will demonstrate the statistical differences in delivered volume with and without an adaptive control system and the resulting higher accuracy that can be achieved.

Improve Liquid Handling Robot Throughput with Direct Path Planning
In Liquid Handling Robots that are properly balanced, the gantry robot utilization reaches close to 100%, meaning the robot is almost always moving. This article (and poster) shows how we have implemented a high-speed motion system on a Liquid Handling Robot gantry that is aware of system clearances so that it can start a planar (X/Y) move while a Z-axis move is still ongoing. By employing such a motion control solution, robot move times can be improved by 25% over conventional robot moves and over 50% compared to systems that only employ single axis moves.
