Roborock uses hybrid ToF system by Infineon and pmdtechnologies for sweeping and mopping robots
Roborock, a global leader in intelligent home robotics, has launched the intelligent sweeping and mopping all-in-one robot Roborock Qrevo Slim at IFA 2024 in Berlin, equipped with an innovative 3D camera module for navigation and obstacle avoidance using the REAL3 Time-of-Flight (ToF) imager by Infineon. The technology allows to reduce size and increase reliability. Compared to the body height of traditional sweeping and mopping robots of around 100 mm, the overall height of the Roborock Qrevo Slim is only 82 mm, allowing it to pass through lower and narrower spaces while providing high reliability.
Roborock has teamed up with Infineon, pmdtechnologies and OMS to develop a next generation robot solution that uses hybrid Time-of-Flight (hToF) to replace the traditional laser distance scanner (LDS) module and obstacle avoidance module. hToF is a combination of Infineon’s REAL3 ToF imager, a dual infra-red illumination sources and pmd’s processing technology to provide a powerful solution for consumer-grade robots. It supports simultaneous localisation and map building (SLAM), obstacle avoidance and cliff detection functions in one camera module manufactured by OMS.
The high-resolution depth and vision data is perfectly suited for robust obstacle avoidance algorithms while the open-source SLAM algorithm based on hToF depth data generates high-precision maps, ensuring accurate and reliable navigation. In addition, hToF is working in darkness and strong sunlight. It is computationally efficient and streamlined, requiring e.g. only one Cortex A55 processor core for depth processing and SLAM computation tasks out of eight available cores.
