OMRON Launches B5L Series Embedded TOF Sensor Module with Three-Dimensional Distance Measurement Capability of People and Objects
KYOTO, Japan, Oct. 15, 2020 /Kyodo JBN-AsiaNet/ --

- Bringing Robots Closer to Everyday Use with High Ambient Light Immunity and 
Durable 3D Sensors -

OMRON Corporation, based in Kyoto, Japan, has announced that it began selling 
the B5L Series embedded 3D TOF Sensor Module in Japan from September 1 and 
globally from October 1. The B5L Series utilizes unique optical design 
technology for stable measurement of three-dimensional distance information 
across a wide area even under sunlight. In addition, B5L also features 
specifications optimized for long periods of continuous operation to allow it 
to be used as an embedded sensor in various instruments. This design results in 
a "mechanical eye" that is capable of accurately and easily detecting the 
surrounding environment, which will contribute to autonomous robots being used 
more frequently in everyday life as well as automation of various other 
machinery and equipment.

The need for manpower-saving solutions has increased in recent times due to 
dwindling labor force and the necessity of avoiding closed spaces, crowded 
places, and close-contact settings during the COVID-19 pandemic. Because of 
this, autonomous robots are being used not only in industrial applications such 
as transportation in factories and distribution warehouses, but also in public 
facilities, hospitals, train stations, and commercial complexes. In addition to 
simple tasks such as transportation, the inclusion of an arm should enable 
robots to engage in more advanced tasks such as component assembly. In such 
varied environments, 3D visual sensors, which enable accurate detection of the 
surroundings to avoid people, obstacles, and uneven surfaces, are necessary to 
achieve autonomous robotic operation of machines and equipment. Cameras and 2D 
LiDAR used in conventional applications, however, have a limited detection 
range, requiring a combination of multiple devices, posing the challenge of a 
complex structure.

The new B5L Series is a 3D sensor module capable of measuring the distance of 
people and objects across a wide range in real time at a distance of 0.5 to 4.0 
m. OMRON's Time of Flight (TOF) sensor detection principle is employed while 
utilizing original optical design technology to enable stable detection under 
sunlight, which was a weakness of TOF normally, resulting in more precise 
detection of distance from objects in various scenes. The module with +/-2% 
precision (at a detection distance of 2m) is optimized for embedding in the 
equipment and features a five-year equivalent (*1) continuous operation. 
Additionally, built-in temperature compensation, etc., makes it easier to mount 
on autonomous robots and other equipment used in a wide variety of applications 
by eliminating the need for compensation processing in the design phase.

The B5L Series can be used not only in robots, but also in applications that 
require detecting the movement of people across a wide area while maintaining 
privacy, such as in caregiver monitoring.

OMRON will continue to globally provide cutting-edge electronic components such 
as sensors that comfortably connect humans and machines, supporting people's 
lives in various situations, and contributing to a smarter society.
