Camera Module: The Key To Enhancing The Perception Capability Of Cleaning Robots

The Tekt V2 Cleaning Robot needs to work continuously in "alternating light-dark scenarios" at home, and the HDR function and 1.4μm×1.4μm pixel size of the SincereFirst Camera Module can accurately meet this demand. On one hand, HDR technology uses multi-exposure fusion to suppress overexposure in bright areas and underexposure in dark areas, preventing the robot from misjudging cleaning boundaries due to "visual overexposure" or missing dust due to "visual underexposure". On the other hand, the 1.4μm pixels increase the light-sensing area of a single pixel, and when combined with the F2.8 large aperture to enhance light intake, the module can still output clear 1080P images even in low-light environments (e.g., with only a nightlight on at night). This helps the robot identify small debris on the ground, making up for the defect of "blurred perception in low light" of traditional sensors and ensuring no cleaning blind spots.

One of the core pain points of the Tekt V2 is its "inability to adapt to uneven floors", and it also needs to climb 1.5cm steps accurately. The "auto-focus + < -1.0% low distortion" features of the OV5640 module can significantly improve its environmental adaptability. First, the auto-focus function supports clear imaging at a close distance of 10cm, enabling it to quickly lock onto small-sized obstacles on the ground and trigger the obstacle avoidance mechanism in advance, preventing the robot from malfunctioning due to rolling over debris. At the same time, the infinite focus range can capture distant cleaning boundaries, assisting the robot in planning a "from edge to center" zigzag path and reducing repeated cleaning or missed areas. Second, the low distortion rate of < -1.0% prevents edge stretching of the image, ensuring the robot's visual judgment of step height and ground protrusions is consistent with actual sizes. This reduces the risk of "getting stuck on steps" or "scratching the floor", and is particularly suitable for scenarios with slight ground height differences such as hotel corridors and home living rooms.

The cleaning efficiency of the Tekt V2 depends on the "rationality of path planning", and the 5MP high-definition resolution, 1080P@30FPS smooth output, and 24Pin MIPI CSI-2 interface of the SincereFirst Camera Module can serve as the core support for the robot's "visual brain". First, the 5MP resolution can restore ground details, allowing the robot to judge "high-pollution areas" based on high-definition images and automatically adjust cleaning intensity, avoiding energy waste caused by "uniform cleaning". Second, the 1080P@30FPS frame rate ensures no motion blur in the image, and when combined with the high-speed data transmission of the MIPI CSI-2 interface, it can transmit environmental images to the robot's main control chip in real time to assist in optimizing the zigzag path. For example, if the image recognizes that "there is no dust in the cleaned area", the robot can directly jump to the uncleaned area, improving overall cleaning efficiency.

The Tekt V2 Cleaning Robot has a size of 280mm×280mm×65mm and needs to pass environmental protection and safety certifications for household and hotel scenarios. The CSP packaging and compliance features of the SincereFirst Camera Module can be seamlessly matched. From the integration perspective, the small size of the CSP package does not occupy too much internal space of the robot, and can be flexibly embedded in the top or front of the robot body without affecting the robot's original lightweight design (net weight 698g) and 1.5cm step-climbing capability. From the compliance perspective, the module is manufactured using SMT (ROHS) technology and has passed certifications such as FCC, CE, and RoSH, and its safety and environmental protection meet the access requirements of global markets.
