The compact sensor with solid-state LiDAR technology boosts productivity and safety of small autonomous vehicles
Conventional safety laser scanners are often not a suitable solution for simple and exceptionally cost-effective small vehicles for economic reasons. Users often choose between limiting the speed or payload of the vehicle or avoid operating them in unfenced areas to minimise any vehicle-related risks.
The scanGrid2 safe multibeam scanner from SICK is a compact sensor that eliminates this issue with the help of a novel and in-house developed solid-state LiDAR technology that increases the productivity of small autonomous and line-guided transport vehicles.
The solid-state LiDAR technology is based on the principle of time-of-flight measurement and eliminates all moving parts. Instead, the device uses only semiconductor elements in conjunction with geometrically arranged optics modules to span a protective field of 150 degrees. Within the defined protective field zone, scanGrid2 can solve Type 2 classified, performance level c safety requirements in the context of safety applications.
The scanGrid2 safely detects objects of various sizes within freely configurable protective field zones, evaluates multiple fields and can execute configurable monitoring cases. A warning field zone extending up to four meters beyond the safe working range can be employed for non-safety actions.
Fast Fleet Deployment
Besides the tried-and-proven infrastructures and tools such as the Safety Designer software, the engineers at SICK have implemented an additional Near Field Communication (NFC) interface. This, in conjunction with the Safety Assistant app, enables diagnostics to be performed on the sensor quickly and easily, such as through a smartphone. The advantages of this approach are also readily apparent during commissioning or servicing. Sensor configurations transfer wirelessly from one sensor to another thanks to a cloning function in the app that ensure a high level of uptime and fast fleet deployment.
“When it comes to the use of safety sensors, easy configuration, fast commissioning, and diagnostics are the key aspects our customers are looking for. Ensuring fast servicing also saves valuable time and money,” said Aaron Woytcke, Market Product Manager of Industrial Safety at SICK USA.
Certified as a Type 2/SIL 1 safety sensor according to IEC 61496-3, the scanGrid2 can protect hazardous areas up to performance level c and works well for collision avoidance. Thanks to the rapid return on investment, switching to a safety sensor is now a viable option with initial installations showing productivity increases between 50% and 70%.
“With this sensor, manufacturers of autonomous and line-guided autonomous vehicles gain a cost-effective safety solution that can boost the productivity of applications. Specifically, this means increasing the speed or payload of the vehicles, or being able to eliminate mechanical barriers like fences,” explained Aaron Woytcke.
