We can imagine that when we get home after a tired day, the smart housekeeper has turned on all the smart devices in the home in advance, and the water heater has been adjusted to a suitable water temperature. The indoor temperature and humidity are automatically adjusted to the best condition. As soon as you get home, you can enjoy delicious food carefully prepared according to the nutritional needs of each family member. After dinner, we can take a bath directly without managing the dishes. The changed clothes will be taken away by the smart housekeeper, cleaned and dried. After taking a bath, we can lie on the sofa, and our favorite movies have already started playing. Just at this time, relatives far away from home called us, and the intelligent housekeeper presented the image of relatives around us through holographic projection, making us feel that the distance of family affection is not important. When resting at night, under the instruction of the robot, the home mode is adjusted to the rest mode. After completing the assigned work, the robot will return to the exclusive cabin door to charge and carry out necessary maintenance to prepare for the next day's work. Focusing on this idea, the team proposed a combined intelligent butler service robot based on the needs of intelligent butler robots in multi-modal interaction, system integration and interconnection, audio and video media functions, scalability and customizability, and adaptability. The combined intelligent butler service robot system consists of three parts: the supervisor's home, the assistant butler and the intelligent cabin door. The supervisor's home includes the head, arms, and torso. As the overall control system, the head integrates intelligent modules such as depth camera, voice recognition module and Internet of things module. The two arms are composed of a five-degree-of-freedom rope-driven mechanical arm and a flexible claw, with flexible grasping and operating capabilities. The torso section integrates sound and holographic projection technology to provide high-quality audio and holographic services. The vice butler is an intelligent mobile platform equipped with binocular cameras and vision algorithms to achieve autonomous navigation capabilities. It has a lifting chassis and deformable wheels, which can adapt to various road environments and can climb steps to ensure smooth movement. The supervisor's home is mounted on top of the deputy housekeeper, allowing the supervisor's home to move anywhere in the home, providing flexible family services and companionship. The smart door is designed to meet the safe placement and charging needs of the robot. It has a placement system that allows for the separation of the robot master and slave, and also provides a temporary workbench function for the master robot. The smart door ensures the safe placement and charging of the robot and provides a temporary working platform for the robot to charge and perform other tasks when not in use. Through the combination of the above three parts, the intelligent housekeeper robot realizes a full range of intelligent services and flexible operation capabilities. The cooperative work of the supervisor and the deputy butler and the provision of intelligent hatch bring more convenience and comfort to family life.
