Liquid Handling, Closed Loop Motion Control, Syringe Dispensing
Automated Liquid Handling systems are the preferred method when accurate dispensing of liquids is required. Two common architectures for dispensing are contact and jet dispensing. This paper will demonstrate motion control dispensing applications where the required motion accuracy can only be achieved with a closed loop control architecture (position feedback).
Everyone who has worked in motion control has a war story, be it the machine that mysteriously stopped working or the motor that wouldn't stop vibrating. Fortunately, common problems often have common solutions.

Economics, Motion Control Techniques
Whether you build your own controller or buy off-the-shelf, knowing how to implement these new approaches is important for maximizing cost-effectiveness, and minimizing project design times. This article examines current control techniques, including a comparison of various commutation techniques.
Noise Control, Common Motion Architecture, Juno Ic, Digital Current Loop, Liquid Handling, Medical Equipment
Conventional step “current chopper” drives result in a large amount of step motor noise, needless motor heating, and consume more current. A digital current loop will result in significantly quieter and lower temperature motor operation which is beneficial in many applications. This article details how a digital current loop will result in a significantly quieter, faster running and lower temperature motor operation which is beneficial in many applications.

Field Oriented Control (Foc), Step Motors, Servo Motors And Drives
Brushless DC, step, and DC brush motors are the three most commonly used motor types for positioning and velocity motion control applications. Of these, brushless DC and step motors are “multi-phase,” meaning they require some type of external coil excitation. Explore the most popular techniques for multi-phase motor control, including Field-oriented Control (FOC), and determine which techniques work best for various positioning and high-speed spinning applications.
Many motion applications require high accuracy both during, and at the end of, the move, but even if you are using perfectly optimized PID values to control position, the compensation loop is never perfect. You can improve motor performance by adding motion control elements outside of the PID loop. In this article, we will look at torque control and the related subject of torque FeedFoward, which will make your equipment run smoother, and deliver better accuracy.
Healthcare / Life Sciences, Motion Control In Robots, Advanced Motion Control
Motion control applications with an operator remotely controlling a robot hand or mechanism can now be expanded to where the operator can “feel” what the robot is touching. This article talks about two common ways to implement robotic hand haptic feedback.
Automation And Robotics, Liquid Handling, Peristaltic Pumps
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.
