Product News: SICK's multiscan 3D LiDAR

April 21, 2023
Promises to provide mobile robots 360°, 3D views of the surrounding area with only one sensor.

SICK’s newest multiScan100 family uses time-of-flight (TOF) measurement to create a 3D perception of its surroundings. The 3D LiDAR sensors provide mobile platforms with a 360° all-round view. With 690,000 measuring points, the multiScan100 achieves a state-of-the-art precision with which nothing in its environment escapes its notice, per its maker. 

With its compact design of around 10 cm and the support of industrial interfaces, a high degree of integration-friendliness is guaranteed by SICK. The first variant, the multiScan136, delivers 3D measurement data that can be used for precise self-localization of vehicles while simultaneously mapping the environment (SLAM, for Simultaneous Localization and Mapping). In addition, the 3D LiDAR sensors can detect falling edges or obstacles in 3D. 

In its main application, the multiScan provides numerous benefits to mobile-robot applications. Industrial mobile robots (IMRs) are used in countless applications across manufacturing and logistics spaces. When mounted on a vehicle, the multiScan supports its navigation and, in parallel, prevents it from collisions. In case of static or dynamic obstacles, the sensor recognizes these and tells the vehicle to stop or drive around them. Additionally, the characteristics of the environment can be detected and measured.

The LiDAR offers obstacle detection at all angles, with a 360° horizontal field of view (FOV) and 65° vertical FOV. With the full field of view of up to 16 layers, the multiScan generates up to 648.000 measurement points per second. This allows the multiScan to create a dense point cloud of the sensor environment to be used to gather navigation and collision prevention data. It also features multi-echo technology and contamination measurement for approved outdoor capability and use in harsher environments. This technology also provides high measurement accuracy with less measurement noise because three echoes are generated per beam, leading to more reliable data.

In addition, measurement filters like rain or dust filters improve the availability and reliability of the sensor because it hides small, irrelevant influences on the measurement data. This includes a dusty environment, or when used in rainy or snowy conditions. It also has a rugged housing design for rough environmental conditions. The multiScan is IP69K rated, with high shock rating and vibration resistance.
