The Prompt series robots focus on small parcel transportation in closed scenarios, with core features including 24/7 continuous operation, 6-camera 360° panoramic monitoring, face recognition/NFC authorization for cabin opening, adaptability to unpaved roads, and security functions such as stranger detection. The USB 4K camera module, with its targeted light effect optimization, high-definition dynamic perception, and compact integration design, can accurately address the core perception pain points of this robot series, enhancing operational efficiency and safety throughout the entire process from "day-night monitoring, dynamic obstacle avoidance, to end-point authorization".
I. 24/7 Full-Light Adaptation: Resolving Pain Points in Complex Day-Night Light Environments
The night-version Prompt robots need to operate on unlit routes, and backlighting scenario are common at park entrances/exits and factory workshops, placing high demands on the camera's low-light and high-contrast imaging capabilities.
STARVIS Technology Ensures Nighttime Imaging Without Supplementary Lighting: By optimizing the photosensitive layer structure of the sensor, the STARVIS technology of the module increases light intake by over 30% compared to ordinary modules in night scenarios while reducing image noise. This enables the Prompt Series A rescue robots to clearly capture the figures of trapped people during nighttime outdoor rescue operations; the S5.2 ISD can also accurately monitor abnormal movements around it when waiting for unloading in the park at night, avoiding security blind spots caused by insufficient light.
HDR Balances Details in High-Contrast Scenarios: For high-contrast environments such as "direct overhead lights and equipment shadows" in factory workshops and "backlit glare and dark areas at guard posts" at community entrances/exits, the HDR function retains details in both bright and dark areas through multi-frame dynamic synthesis. For example, when the S7 is transporting in industrial workshops, it can clearly identify material labels under overhead lights and pedestrians in shadows, avoiding obstacle avoidance errors caused by overexposure or underexposure.
Prompt robots need to perform dynamic obstacle avoidance on narrow walkways and factory corridors, and rely on face recognition to complete recipient authorization, requiring high clarity of details and dynamic smoothness of images.
4K@60FPS Achieves Dual Guarantees of "Details + Smoothness": The 4K resolution (3840×2160) can capture details such as facial pores and glasses reflections of recipients within 3-5 meters, meeting the accuracy requirements of the robot's face recognition algorithm and avoiding authorization failures; the 60FPS frame rate eliminates image blurring when the robot is moving, and fully presents the trajectories of suddenly passing workers and rolling material boxes. Compared with 30FPS modules, it can gain an additional 0.15 seconds of response time for the obstacle avoidance system, reducing the risk of collision.
Multiple Output Formats Adapt to Multi-Scenario Needs: The module supports MJPG/YUY2/H.264 formats — the compression feature of H.264 can reduce the bandwidth occupation of 6-camera panoramic monitoring, adapting to the limited on-board computing power of the robot; the lossless output of MJPG provides high-definition details in scenarios such as "parcel QR code scanning verification" and "rescue material label recognition", balancing the needs of "real-time monitoring" and "accurate interaction".
Prompt robots achieve 360° panoramic monitoring through 6 cameras mounted on the mast, requiring the integration of multiple modules in the limited mast space, and also need to support customized security functions such as stranger detection and audio intercom linkage.
Small Size + Universal Interface Simplifies Omnidirectional Integration: With a size of only 38mm×38mm, the module can be flexibly embedded in 6 monitoring positions on the robot's mast without affecting the overall center of gravity of the robot; the Type-C interface supports reversible plugging, and combined with USB 3.0 high-speed transmission, it can be quickly connected to the robot's embedded system (e.g., Linux). The UVC protocol enables "plug-and-play", significantly shortening the debugging cycle of the 6 cameras and aligning with the robot's positioning of "efficient operation on repeated routes".
SDK Supports Customized Security Functions: The module provides an SDK interface, which can be used to develop exclusive algorithms based on the security needs of Prompt robots. For example, when the S5.2 ISD detects a stranger, the module can link with the robot's audio intercom system to initiate an inquiry, while capturing the stranger's features through high-definition images; if an unauthorized person is identified approaching the cargo compartment, it can trigger an alarm signal, enhancing the dual value of "delivery + security".
Prompt robots need to operate on gravel roads and outdoor off-road scenarios, and may be deployed in European and American factory parks, placing high demands on the module's vibration resistance and compliance.
Precision Manufacturing Withstands Complex Road Conditions: The module adopts SMT process and AA (Active Alignment) process, with an alignment accuracy error of ≤0.01mm between the lens and the sensor. It can withstand the vibration of the robot on gravel roads and small potholes, avoiding imaging deviation; the temperature change resistance adapts to the day-night temperature difference of Series A outdoor rescue robots, ensuring monitoring stability in low-temperature/high-temperature environments.
Multiple International Certifications Facilitate Market Access: FCC/CE/RoSH certifications enable the module to adapt to the deployment of Prompt robots in European and American markets without additional certification costs, meeting the needs of enterprises for "global park operation". At the same time, the RoSH environmental protection feature is also in line with the green production standards of factories.
The cargo compartment of Prompt robots needs to be opened through face recognition/NFC authorization, and parcel verification via scanning is required during end-point delivery, requiring high focusing flexibility and detail accuracy of the camera.
The 1cm~Infinity manual focusing of the module allows flexible scenario switching: in close-range scenarios (1-3cm), it can clearly scan parcel QR codes, avoiding the deviation of auto-focus when multiple parcels are stacked; in long-range scenarios (3-5 meters), it can lock the recipient's face, and combined with 4K resolution, it improves the success rate of face recognition, reducing recipient waiting time caused by focusing delay. In addition, the lossless output of MJPG ensures no distortion of NFC tags/facial details, further optimizing the efficiency of the "authorization - cabin opening - parcel receipt" end-point process.
Prompt S5.2 ISD Community Security and Delivery: The STARVIS+HDR of the IMX415 ensures nighttime monitoring in unlit communities, 4K face recognition guarantees owner-authorized cabin opening, and the integration of 6 modules adapts to omnidirectional security, preventing strangers from illegally accessing the cargo compartment. At the same time, SDK-customized abnormal behavior detection can link with alarms to enhance community security.
Prompt S7 Industrial Workshop Logistics: The vibration resistance of the module adapts to the gravel roads in factories, 4K@60FPS captures workshop workers/materials for more accurate obstacle avoidance; the SDK-customized material label scanning algorithm can automatically verify transported materials, reducing manual intervention and meeting the needs of "industrial automated logistics".
Prompt Series A Outdoor Rescue: The small size and temperature change resistance adapt to the off-road structure, STARVIS captures trapped people in nighttime rescue scenarios, long-range focusing cooperates with the robot's corner reflector for positioning to support accurate delivery of emergency medical supplies, and high-definition images can assist in remote command.
In summary, with its five core advantages of "full-light adaptation, high-definition dynamics, compact intelligence, compliance and weather resistance, and accurate interaction", the USB 4K camera module deeply matches the needs of Prompt series robots for closed-scenario delivery, 24/7 security, and complex working conditions. It directly enhances their operational safety and efficiency from the perception layer, making it an ideal visual component for such dedicated delivery robots in closed scenarios.
