Sophisticated coordination between elevators and mobile robots assists robot operations and promotes coexistence with people. *Mobile robots need to be arranged separately by each customer. Please consult our local agents for details. 3 Increased operational eﬃciency Combining functional systems that increase operational ef ciency improves transport ef ciency and waiting time, and realizes a smoother and more comfortable ride. ■Quick-motion Door System An optimized door design shortens the door opening and closing time. Furthermore, by combining this feature with the Landing Open [LO] feature (Optional) , the door opens at optimum timing, thereby increasing transport ef ciency by approximately 12% and reducing average waiting time by approximately 14% compared to conventional models. 5-min. transport efficiency(%) Approx. 12% increase Conventional model with Landing Open NEXIEZ-MRL Version 2 (optimized door design) with Landing Open Average waiting time（sec.） Approx. 14%reduction 17.2 14.7 Conventional model with Landing Open NEXIEZ-MRL Version 2 (optimized door design) with Landing Open Simulated with 2 cars, 13 persons each at 1 .0m/sec for 4 stops. Making it more ef cient ■Quick Closing System with Sensor [SNCD] Optional When the sensor installed above the car doors detects no passengers in the elevator hall, the doors begin closing after a shorter amount of time than usual. Thus, average waiting time can be further reduced by 10% . *Waiting time can be reduced by approximately 24%(14% + 10%) in combination with the above Quick-motion Door System. Please consult our local agents for details. *This feature is not applicable to the environment where the sensors are exposed to direct or re􀀞ected sunlight because false detection may occur. *The effects on transport ef ciency and waiting time differ depending on building conditions. Quick Closing System with Sensor ΣAI-2200C and Mitsubishi Electricʼs original AI technology Optional The ΣAI-2200C group control system uses our original AI technology to predict the traf c 􀀞ow in the building in few minutes’time based on current traf c information. A real-time simulator evaluates various rule-sets and selects an optimum rule-set for the predicted traf c 􀀞ow to ensure smooth operation.
