AI Technical Summary
During autonomous charging, existing service robots experience a shift in their center of gravity due to waist rotation, affecting docking accuracy and safety. Furthermore, the interactive interface cannot remain continuously facing the user, leading to service interruptions and a decline in user experience.
The system employs a multi-axis linkage control method with a rotatable waist. The upper body interaction unit is driven to turn towards the user through the waist rotation joint. Combined with chassis pre-adjustment, center of gravity compensation, and deviation correction, the system calculates the compensation displacement in real time and superimposes it onto the chassis motion command to achieve center of gravity stability and docking accuracy.
During charging, the upper body interaction unit should be kept facing the user to avoid chassis shaking, improve docking success rate and accuracy, and enhance user experience and the stability and safety of autonomous charging.
