Launched 3D-LiDAR "RS-Bpearl" for ultra-wide-angle & ultra-short distance measurement

-Viewing angle of 90 ° × 360 ° and shortest measuring distance of 5 cm for detecting peripheral areas and blind spots of robots-

ZMP Inc. in Bunkyo-ku, Tokyo, (CEO, Hisashi Taniguchi, hereafter ZMP) have started the sale of 3D-LiDAR "RS-Bpearl", a RoboSense product (Headquartered in Shenzhen City). It is an ultra-wide-angle and ultra-short-distance measurement developed and mass-produced to eliminate blind spots in transport robots and autonomous vehicles. The hemispherical design enables flexible and compact mechanical design.

Shortest measuring distance less than 5 cm
Most commercially available LiDARs have the shortest measuring distance of 20 to 50 cm, but it cannot be said that the surrounding obstacles can be perfectly recognized. RS-Bpearl can detect obstacles in the immediate vicinity of robots and vehicles because the shortest measurement distance is less than 5 cm. The maximum measurement distance is 100m, which can be used for measuring the surroundings of robots and vehicles used in narrow passages and places with heavy traffic, and for detecting obstacles.

RS-Bpearl can measure vertical viewing angle of 90 °, horizontal viewing angle of 360 ° and super wide angle. By attaching it to the upper part of a moving body such as a robot or vehicle, it is possible to grasp the ceiling height and shape of tunnels and underdrains, improve judgment in automatic driving, and ensure further safety.

The size of RS-B pearl is 100mm in diameter x 111mm in height, and by embedding the parts other than the optical part of the upper hemisphere in the airframe, a flexible and compact design is possible.
