Serving robot and control method thereof

In-flight meal serving robot combining an autonomous cart, robotic arm, and voice recognition

This technology is a system that autonomously serves and collects in-flight meals by integrating a robotic arm and support structure onto a meal cart. It includes GPU-based autonomous driving and stop control, voice recognition-based meal selection, meal tray transport using primary and secondary rails, and a precision delivery process via a robotic arm gripper.

In-flight meal service is currently performed manually by flight attendants, which poses risks of injury and health issues due to the handling of heavy carts, creating a continuous demand for automated serving systems.

This technology implements autonomous meal service through a serving robot equipped with a robotic arm (including a gripper) and a rail-based tray transport structure. It automates the process using object recognition technology linked to voice and seat databases, along with verification and error-checking algorithms utilizing the robotic arm's camera and object recognition sensors. Applicable to in-flight services, food and beverage serving robots, and meal distribution automation, it reduces the physical burden and accident risks for flight attendants while increasing service efficiency.

Key Features:

• A step of transmitting the passenger's voice signal recognized by the voice recognition sensor to the control unit's voice extraction GPU and voice processing GPU, and controlling the selection of the ordered in-flight meal by processing the voice signal into the meal name.
• A step of controlling the system to verify errors by comparing the number of actually delivered meal trays with the pre-established in-flight meal database for each seat.
• A step of controlling the system to verify successful delivery to the passenger using the robotic arm camera and the primary object recognition sensor upon completion of transport.
• A step of controlling the secondary rails, formed in multiple layers, to operate and transport the meal tray toward the support structure.
