The  SSLT S40 service robot has the functions of intelligent welcome reception, intelligent consultation, navigation, guide and explanation, intelligent preaching, active avoidance and automatic charging. Suitable for libraries, enterprises, hospitals, public office halls, museums and other public places.
Function description:
1, intelligent welcome image: artificial intelligence of the image publicity spokesman, with its own publicity effect. At the same time, artificial intelligence technology can alleviate the shortage of human resources, improve service efficiency and enhance service experience.
2, professional service knowledge: the robot can collect massive knowledge base information, has professional business knowledge, can reply to guests through consultation, give corresponding service suggestions.
3, voice interaction: four mai array, speech recognition, guests interact with the robot through the voice, the robot can recognize the guest's voice, answer the guest's questions. Guests can chat with the robot briefly, say hello daily and discuss the weather. Experience a new natural human-computer interaction.
4, touch screen interaction: guests according to the display content or options, the corresponding operations.
5. Welcome the guest: When the robot detects the guest's face, it takes the initiative to greet the guest.
6, face recognition: automatically recognize the face through the camera, collect visitor identity information, according to the face database has been entered for quick retrieval, identify the identity of the guests, and take the initiative to welcome the guests.
7, intelligent consultation: you can increase the professional knowledge base in the background, so that the robot can answer the common questions of the guests, the answer form in addition to voice, support according to the answer content, with the corresponding screen display. Support for frequently asked questions updates, support for user-defined questions. Supports single item addition and batch import of questions, and supports multiple different similar questions for the same question.
8, intelligent propaganda: the robot supports to introduce, display, publicize service content and service process to guests in various forms such as pictures, audio, video, text, voice, etc. Users can choose the content to be presented, and users can customize the introduction content and method.
9, navigation directions: the robot uses a combination of multiple sensors, ultrasonic sensors and lidar sensors to double guarantee, after building a map can achieve guidance function, can guide guests. Support taking guests from your location or designated location to your destination.
10, guide to explain the use of advanced SLAM technology, independent creation of environmental maps. Single point guide: can lead the guests from the welcome position to the place where the guests want to go (on the way can explain the introduction service), guide the task is finished, and then return to the welcome point; One-click guide: can guide guests from the welcome position to the A position to the B position to the C position (on the way to explain the service), etc., guide the task is completed, and then return to the welcome point. Through the input and learning of knowledge, the professional knowledge information of the location can be explained at a fixed point, and the content can be further publicized.
11, active obstacle avoidance In the process of guidance encountered obstacles, the robot can easily bypass, re-plan the path, avoid obstacles, work more efficient and safer.
Emergency stop button In order to ensure safety, the emergency stop button can be pressed to stop the robot in an abnormal state.
12, autonomous charging When the robot power is insufficient, it can return to the charging pile to charge.
13, the secondary development robot can provide SDK interface to support the secondary development of front-end applications.
