mmWave IWR – Safety Guards

Discover

With factories? becoming smarter, man and machine work “hand in hand”. In this scenario, to reduce possibility of? potential hazards if there is a flaw or bug in automation, incident management through Safety Guards is becoming important. TI’s Industrial mmWave sensors can be used for high accuracy occupancy detection and collision avoidance, where the position and velocity of people can be used to trigger systems when a person or an object is in proximity of a machine.?mmWave sensors bring additional value by seeing in challenging environments, such as poor lighting and dusty factory conditions. These features make mmWave the obvious choice for sensing considering privacy and solution complexity to enable intelligence and at-the-edge decision-making. In addition to the above, the Antenna on Package’s wide field of view, small form factor and simplified design and manufacturing process, users can now take their robotics solutions to the next level? in sensing.?
