  • What is a Cobot?

    February 06, 2018, by Emily Blanchard

    A collaborative robot (or Cobot) is a robot that is made to work with or interact with human co-workers. For most of us normal folks, the most well-known example is Tony Stark’s robotic arm. (For those reading who are wondering why I don’t refer to the arm as JARVIS, it’s because JARVIS is the AI and controls other things but not the robotic arm.) Tony has bit of an unhealthy relationship with the robotic arm, he insults it, puts it in a dunce cap, puts it in time out, or threatens to dismantle it. At which point the robotic arm usually hangs his robotic limb downward into sadness. But, the robotic arm is there to do work for Tony in his basement. He may have a large house, but he doesn’t want a 10-foot-tall robot behind a fence. He wants an assistant, a co-worker of sorts that can help build his Iron Man suits.

  • We’ve covered feedback devices before in our Blog in Motion posts, but today we want to touch base on current trends we are seeing related to feedback devices for servo applications. We asked Dan Wolke a few questions about where we see the market heading.

  • On November 13, 2017 FDA approved a pill that can digitally track if a patient has taken their medication.  The pill is called “Abilify MyCite” and is used to make sure that patients with conditions such as schizophrenia have actually ingested their medication.  As news broke about this new tracking pill it rekindled both concern and excitement about technology in the field of medicine.

  • A few years ago I watched the DARPA challenge. If you’re not familiar with the challenge, the idea was to build a robot that could drive a car, climb a ladder, turn a handle, use a drill and various other activities.  In the challenge each robot was given an hour to complete the tasks.  It was a slow process. I had two reasons to watch, one, Kollmorgen has some frameless motors in the Carnegie Mellon robot and two, I’m a Virginia Tech graduate and they also provided a robot.

  • Last time in our Block and Tackle Series on “What is a Linear Actuator?” we identified the general types of mechanisms that are used to move loads in a straight line.  Today’s blog expands on that just a bit with a few more details on the different types used in the motion control world.

  • What is Mechatronics?

    October 04, 2017, by Bob White

    Mechatronics is taking a holistic look at a complete machine solution, taking account of all elements that make up that system that are part of the machine, including mechanisms, motors, drive electronics, controls, interfaces, and ergonomics.  A variety of disciplines are involved when considering a machine design utilizing a mechatronics approach. It is a melding of the physical expectations of a motion system whether mechanical, electronic, hydraulic, pneumatic or any hybrid of technologies used to accomplish a physical task. Often, these systems are trying to duplicate, simplify, or assist a human function, most often a repetitive motion that a machine can do better.

  • Question: What is a linear actuator?

    Answer: Quite simply, a linear actuator is a device that moves a load in a straight line.  Linear actuators come in many styles and configurations – our blog post today covers those actuators associated with motion control.

  • In our last blog related to decentralized drives, we indicated several key customer benefits tied to using this approach.  First, you can reduce your cable costs significantly in machine configurations with lots of axes spread apart throughout the machine.  Second, a reduction in cabinet space and cooling requirements since you’ve taken a number of heat producing elements (Servo drives) from the enclosure.  Thirdly, you increase flexibility in design. In this blog entry, we will explore what is meant by flexibility and how this offers several advantages.

  • Less Cabling, Smaller Cabinet, Less Heat…More Flexibility!  Less Cabling, Smaller controls cabinet, Less heat…wow, that’s all great stuff.  I can achieve this all with a decentralized solution?   Absolutely – and even more! Decentralized Control Architecture means shifting the motion control drives from the crowded cabinets, and moving them near to the motors – out on the machine where the action is.  Immediately you can see that this can reduce the size of the controls cabinet, moving all of those drives out onto the machine – but how do I see these other advantages?

  • Block and Tackle Series Volume 4 – What does TENV (Totally Enclosed Non-Ventilated) mean?

    Question: What does TENV, or Totally Enclosed Non-Ventilated mean in regard to a servo motor?

    Answer: Well – the answer is simply the motor is Totally Enclosed, and Non-Ventilated. Based on NEMA (National Electrical Manufacturers Association) definition, TENV states that the motor housing is fully enclosed and is not ventilated with a fan.
