3-Axis Parallel Robot with AlphaStep Absolute Stepper Motors

Posted by Johann Tang on Oct 29, 2020 8:25:46 PM

Remember the days when we used to go to in-person events, such as trade shows?  Robot demos have always generated a lot of foot traffic in booths.  What's better to illustrate the synchronism of closed-loop stepper motors than 3 motors working together to create one specific motion?

Monitor Your Machine Like a Traffic Light System

Posted by Johann Tang on Jun 19, 2020 8:00:00 PM

For automated factories, motor failures mean lost production and lost revenue.  Being able to identify the specific issue in advance and its location is critical to maintaining production efficiency.  To be successful, extra sensors must be added to detect abnormalities.  There may be an easier way.

Control Basics: The Difference Between Sink and Source Logic

Posted by Johann Tang on Apr 30, 2020 9:16:14 PM

For someone who has never had experience wiring I/O for motion control, it can be scary the first time.  If devices are not wired correctly, it can cause a range of issues from a motor simply not doing what's expected to irreversible product damage.  I still get that nervous feeling before I press the START button on a demo.  Murphy's Law, anyone?

Gear Basics: Backlash vs Lost Motion

Posted by Johann Tang on Apr 29, 2020 9:13:21 PM

The significance of position control accuracy of motors varies depending on the application.  For an AGV in a farm with DC motor-driven wheels, position control accuracy is probably not as crucial as a surgical robot where incisions are controlled by servo motors or stepper motors.
