Nowadays it is impossible to imagine industry without robots. Safety laser scanners mostly safeguard dangerous areas and protect people from collisions. But optical sensors have their limitations, for instance when plastic surfaces, dust or smoke obstruct their line of sight. Fraunhofer researchers have developed a new, high-frequency radar scanner that cuts through these obstacles. It can monitor its environment in a 360-degree radius, making it ideal for safety applications wherever people and robots work together.
