One of the key requirements for delivery robots is natural communication with users. In busy restaurant settings, voice control offers a more efficient alternative to manual input, streamlining interactions for both staff and customers. Powered by the SIM8668, built on the RK3568 platform with 1 TOPS NPU performance, these robots are optimized for lightweight AI tasks such as facial expression recognition, storing user preference data, speech recognition, command processing, and interactive responses.

With this capability, robots can be activated using specific wake-up words and can immediately respond to user instructions without the need for physical interaction. Powered by SIM8668, which supports TensorFlow, MXNet, PyTorch, and Caffe, delivery robots gain enhanced AI model training and faster inference. During meal delivery, they automatically broadcast reminders for food pickup. If there is no response, the robots are even capable of dialing a preset contact number via the system, ensuring that meals are not delayed. These features highlight how moderate AI computing is sufficient for real-time, responsive voice interaction, making the robots both practical and user-friendly.

At the same time, reliable navigation is critical to any delivery robot. Delivery robots should move smoothly through crowded hotel lobbies or shopping centers without deviating from their path.

Beyond communication, delivery robots also depend on stable and intelligent navigation to operate in complex, dynamic environments. With the SIM8668, they can perform accurate mapping and localization even in crowded hotel lobbies or busy restaurants. This ensures they avoid obstacles, stay on course, and complete tasks reliably. The SIM8668 further supports INT8/INT16 precision and quantization, allowing developers to apply quantization-aware training or post-training calibration to maintain performance while optimizing efficiency for real-world delivery robot applications.

The SIM8668 supports a wide variety of interfaces, including LVDS, MIPI-DSI, HDMI, CSI, USB, PCIe, UART, SPI, and I2C. This rich connectivity allows the integration of multiple external cameras, displays, sensors, and positioning systems. With these components working together, the robot can collect data from its surroundings, fuse information from multiple sensors, and navigate smoothly within defined areas. The result is an intelligent system that can move freely without drifting off course, ensuring reliable performance even in environments full of people and obstacles.

By integrating the SIM8668, delivery robots achieve a new level of intelligence, reliability, and affordability. They are capable of providing smooth voice interaction, accurate navigation, and stable operation without relying on expensive high-computing platforms. This makes them not only more practical for businesses but also more scalable, paving the way for wider adoption in the service industry. With SIMCom’s low-computing smart modules, delivery robots are transforming into valuable assets that reduce operational costs, enhance customer experience, and bring automation into everyday life.
