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.
Big or small, selecting the right encoder for your motion control application is crucial to meeting your system requirements.
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.

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.
Closed Loop Motion Control
Step motors are a common solution for controlling the position of moving components, but in some cases can be inadequate since the motor position is not necessarily known. Even though step motors are inexpensive when compared to Brushless motors, in many critical applications, care has to be taken to ensure that when a command is given to the step motor controller, the motor actually ends up where the user wants it to go. In this article, we will look at each motor control design option and provide an in-depth review of a new closed-loop motion control system.
Several trends have been driving the use of sophisticated, complex motor control algorithms. The most important of these trends include the desire for lower energy consumption and the need for higher performance. In this article, Chuck Lewin addresses these trends and introduces the major techniques used to control multi-phase motors, both Brushless DC and AC induction.
This article will review the mathematics of motion profiles and help you understand which profiles work best for which applications. You'll gain valuable insights into how to tune your motion control profile for maximum performance.
Motion Control Techniques
Explore why a machine is exhibiting mechanical resonant frequency and what tools can be used to analyze it.
Examine trends and review the four major motion control architectures in use today. Two of these can be traced back to earlier motion control approaches, and two are more recent additions.
A detailed look at design choices for building a machine controller that provides precision motion control. This article addresses whether it is best to build or buy motion control hardware and software, and what aspects of your application are most important for determining the architecture of your machine controller.
