Robotics, Automaton and Automation Design GS X ONE Food Delivery Robot by Shanghai Gaussian Automation Tech Dev. GS-X One is a food delivery robot for restaurants. The robot connects to the smart service system of a restaurant. Dual positioning cameras at the top and the bottom perceive the environment and plan paths for contactless delivery. An ascending stepped structure holds the serving trays and keeps them easy to place and remove. Paired with a workstation, GS-X One recharges automatically and delivers food around the clock without staff. The robot also measures temperature, which supports epidemic prevention and control.
