OMRON Launches B5L Series Embedded TOF Sensor Module with Three-Dimensional Distance Measurement Capability of People and Objects - Bringing Robots Closer to Everyday Use with High Ambient Light Immunity and Durable 3D Sensors -

  • September 15, 2020

OMRON Corporation (HQ: Shimogyo-Ku, Kyoto; President and CEO: Yoshihito Yamada), announced that it will begin 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 feature 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 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. The cameras and 2D LiDAR used in conventional applications, however, have a limited detection range, requiring a combination of multiple devices, posing the challenges 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 2 m) is optimized for embedding in 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.
