Summary

An Intelligent-Cloud Edge Multimodal Interaction System for Robots addresses robust human-robot interaction in complex environments with limited onboard computing. This framework integrates an enhanced YOLO-based gesture detector, named YOLO-DC, with coordinated large language model (LLM) and vision-language model (VLM) agents. YOLO-DC incorporates the Convolutional Block Attention Module (CBAM) into its neck and uses Distance-IoU (DIoU) loss for bounding-box regression, improving feature discrimination and localization for small or partially occluded gestures. The cloud layer handles gesture detection, scene understanding, multimodal fusion, and action planning, while the TonyPi robot manages local data acquisition, communication, action execution, and feedback. Experiments show YOLO-DC achieved 98.9% and 95.0% precision, with mAP@0.5 values of 90.7% and 92.7% on public and custom gesture datasets, respectively. System-level evaluations yielded 95%, 88%, and 82% success rates for single-action, composite-action, and vision-dependent tasks, with a 3.69/5 mean satisfaction score from 30 participants.

Key takeaway

For Robotics Engineers designing human-robot interaction systems, especially with resource-constrained platforms, consider a cloud-edge architecture. This approach allows you to offload complex tasks like gesture detection, scene understanding, and action planning to the cloud. The robot then handles local execution. Implementing enhanced detectors, such as YOLO-DC with CBAM and DIoU loss, can significantly improve interaction accuracy and user satisfaction.
