Navigating Drop-Offs with the R2300 LiDAR Sensor

Posted by Aaron English on Thu, Sep 17, 2020

Mobile robots typically use some version of a LiDAR sensor for navigation. LiDAR, which stands for light detection and ranging, is a remote sensing method that measures variable distances using light in the form of a pulsed laser. LiDAR helps localize, navigate, and avoid obstacles so the robot can perceive surroundings and select a collision-free path. As new industries continue to adopt mobile robots, they must be able to navigate new, dynamic environments. One of the challenges in these environments is navigating around drop-offs or cliffs, also known as negative obstacles.

Ask an Expert Industrial Sensors - Episode 19

Posted by John Appleson on Fri, Jul 22, 2016

This episode of Ask an Expert for industrial sensors examines and provides answers to interesting sensing questions we've received from customers just like you. We explore and answer these questions:

1. Can the inductive sensor NJ6-F-N operate at -40 °C?
2. How far can a target reflector move sideways before a photoelectric sensor can't read it anymore?
3. Do you have distance sensors compatible with EtherNet/IP and ControlLogix Safety PLC?
4. What sensors could sense plastics and metals through a plastic tray?

5 Things to Look for When Comparing LIDAR Scanners

Posted by Patricia Stafford on Tue, May 31, 2016

This LIDAR image was recorded with the Pepperl+Fuchs R2000 LIDAR scanner. The R2000 was mounted vertically on a rail car. From there, the sensor recorded slices of its surroundings and translated the information into distance and reflectivity values. The 3-D point cloud was then processed by a powerful computer program that put together the image based on the distance and reflectivity data. Since the R2000 has a 360° field of view, it created a full view of the street.

What’s the Big Deal about Discrete Outputs on a 2-D Laser Scanner?

Posted by Colton Rentsch on Fri, Apr 15, 2016

What is a 2-D laser scanner?

A 2-D laser scanner consists of a light beam that’s rotated or fanned around a circular path in order to detect anything that is in the plane of the light beam. The light beam emitted will measure both the distance and the angle to the given object in the plane of view.

Boosting Productivity with the Help of Laser Barcode Scanners

Posted by Tim Cicerchi on Thu, Jun 25, 2015

Laser barcode scanners have been used in material handling applications for decades.  It is an integral part of routing boxes down a conveyor line.  The production of products such as liquid soaps, lotions, and shampoo will use barcode readers also.  They are used in two places.  First, to read the pallets of raw material bottles at the beginning of the production line, then secondly, at the end of the line after barcodes are applied to the bottles.  The barcode readers have to read at very high read rates of over 200 bottles per minute.

Laser Sensors that Measure the Distance!

Posted by Amanda Blakeman on Thu, May 07, 2015

You read that right.  Now with Pulse Ranging Technology (PRT), laser sensors can determine the distance to an object by emitting short, high-energy light pulses over a given distance.

How Do I Program a Laser Displacement Sensor?

Posted by Sean Miller on Tue, Jul 23, 2013

When you purchase a laser displacement sensor, it will likely not be set up for your specific application out of the box. Programming instructions are included, but can be confusing to a first-time user. Let‘s take a look at programming one of the more popular series.

5 Reasons to Choose a Rotary Encoder

Posted by Robert Pasho on Thu, Mar 28, 2013

Instead of laser displacement sensors

When you’re looking for a solution to a problem or application, there may be a few different ways of solving it.  How do you decide which one to use? You usually try to find reasons for why you would use one device over another. I will give you 5 reasons why I would choose a rotary encoder over laser displacement sensors.
