Welcome to Oriental Motor's "Engineering Notes" Blog:

A gripper is typically an end effector that is installed at the end of a robotic arm or on a cartesian robot and can be used to grip parts in order to transfer them from one location to another.  However, there's more to it than just closing the jaws to pinch a part.  

In the spirit of Thanksgiving, I thought I'd change gears (pun intended) and write about what Oriental Motor is thankful for.  

First, we are thankful for our customers for being our customers and helping us grow to be a globally reputable motion control manufacturer. 

Second, we are thankful for the awards and recognition we've received over the years.  It's always good to know that we're doing a good job and these accolades definitely serve as motivation to become even better at what we do.

While we are grateful for these awards and recognition, our greatest satisfaction comes from applying our award-winning products to solve motion control challenges for our customers.

The terms "absolute" and "incremental" come up frequently in the world of position control.  The exact meaning can be the type of motion done by the motor in programming terms or the type of feedback device used with the motor.  In this article, we will focus on the differences between an incremental closed-loop feedback system and an absolute closed-loop feedback system.

The word, "AlphaStep", describes Oriental Motor's patented Hybrid Control technology, which offers improved stepper motor performance by sensing the rotor position and automatically switching between open-loop and closed-loop operation when necessary.  This post explains the unique technologies offered within the AlphaStep family of products and summarizes the numerous integrated options available.  It also can serve as a website navigation guide (video added).

Robot adoption is increasing in many industries due to global efforts in reducing long term costs, maintaining quality, and freeing up time for humans to do "human" tasks.  For example, by using a robot to clean floors or restock shelves in a supermarket, human employees can spend more time helping or selling to their customers.  A company can either tap into this robotic trend by buying ready-made robots, or by making their own with less cost. 

If engineering resources are limited, selecting the right components can reduce the difficulty and time for building a robot.

There are many mechanisms that convert rotary motion of an electric motor to linear motion, such as belt/chain drives, screw drives, rack & pinion drives and even CAM drives.  Each mechanism offers advantages and disadvantages. Choosing the right technology can help increase load, speed, travel distance, or positioning accuracy.

In the world of industrial robotics, there are several types of robots typically offering multiple axes of motion for tasks such as parts assembly, material handling, or pick and place operations.  These include articulated robots, cartesian/gantry robots, SCARA robots, and Delta robots.  Variations of end effectors such as grippers, welders or part rotators can be mounted on the end of the arm to perform different tasks.  Depending on number of axes or load capacity, costs can easily add up.  Limiting the operation range for these robotic axes of motion is an easy way to prevent costly problems or safety issues later.

With recent trends focusing on improving engineering efficiency, many products have been developed to specifically help shorten design cycles for machine automation.  Part of improving efficiency is making products easier to use, so additional time and resources can be spent elsewhere.  This post describes a product feature that can make index table applications less complex to manage.

Automation is great for repetitive tasks, such as test fixtures for a process that has to repeated.  In this post, we will explain how to perform a reciprocating motion (back and forth cycles) with a product that does not require a PLC or external presence sensors, which can help speed up design cycles.
