Description of Features
Item Delivery
GL-H2 is equipped with two large-capacity item delivery bays, making it suitable for a variety of delivery scenarios such as the delivery of take-out, common disposable goods, wines and drinks. Through unmanned operation, it enables multi-point delivery and replaces the service staff, thus reducing the operating costs of hotels, office buildings, and other places.
The robot supports cross-floor delivery, autonomous elevator calling and taking, and autonomous path-finding.
Example of item delivery process The service staff will perform operations on the screen, place the items into the delivery bay, and enter the room number. Then, the robot will automatically deliver items to the corresponding room and make a call to notify the customer. After the delivery, the robot will return to the charging station automatically.
The robot has two delivery bays. Different from traditional services, it can be dispatched at will. By enabling multi-point delivery at a time, it reduces labor costs while improving operational efficiency.
When the robot is in use, the service staff will run the App on the screen, place the items into the delivery bay, and enter the room number. Then, the robot will automatically deliver items to the corresponding room and call the room phone to notify the customer. After the delivery, the robot will return to the charging station automatically.
Step 1: Home Delivery Services Tap “Home Delivery Services”. Enter the room number, put the items into the bay, and then tap “Start Delivery”.
Step 2: Deliver items to the target room After receiving the delivery task, the robot will autonomously plan the path. After reaching the target room, it will notify the user of item pick-up via a call.
Step 3: Pick up the items The user picks up the items by following the instructions on the screen and taps “Close”.
Step 4: Return automatically After the user picks up the items, the robot will return automatically.
