"Hello, pomelo, what's the weather like today?" "It's a rainy day today, so wear more!"
"Hello, Xiaosa, turn on the sanitize function" "Okay, Xiaosa is going to turn on the spray mode." ”
On April 8, in the science and technology innovation laboratory for college students on the Nanchong campus of Southwest Petroleum University, the instructor Ye Chuan was taking 4 students to do debugging. In front of them are two newly developed intelligent interactive robots "Xiaoyu" and "Xiaosa", one focusing on home intelligent escort and the other for intelligent sanitization. "At present, both robots have entered a state of commissioning and continuous upgrading, and the patent application will be completed this month. ”
Family escort robot "pomelo"
Intelligent, playful, and expressive
"'Xiaoyu' is a smart home robot, focusing on the elderly at home. You can talk to the elderly through voice recognition, you can check the weather, tell stories, tell jokes, play music, have the function of detecting the fall of the elderly, and have the function of keeping pets. Cheng Xiaotian, a sophomore majoring in electronic information, is the chief programmer of the robot "Xiaoyu".

"One of the focuses of R&D is language model building and training. Cheng Xiaotian introduced that in addition to the R&D positioning of Xiaoyu, in addition to wisdom and intelligence, I also hope to have some surprises, such as voice answers are lively and playful, so that the elderly can feel the value of companionship and emotional value. "We have done a lot of question-and-answer debugging and training, so that the robot has gone from not knowing what to ask at the beginning, to what to ask and what to answer, and now the answers are becoming more and more playful and lively. ”
For example, when asked if "Yuzu" is a boy or a girl, the robot will reply, "I am a peerless beautiful man". "This is an answer that is not preset in the program code, and it belongs to Xiaoyu's own training. ”
Sun Rongshu, a third-year student majoring in electronic information, is the designer of Xiaoyu. This is the second robot R&D project he has participated in since joining the Science and Technology Innovation Lab. "Pomelo's design focuses on spatial harmony and smooth lines. The chassis part has multiple sensors, the circular body part is the main control system equivalent to the brain, and there is a display on the top, which is equivalent to the 'face' of the robot, which can present different expressions according to real-time answers. Sun Rongshu introduced that Xiaoyu's "face" is flexible and moving, can nod his head, and can also have a lifelike expression. The next direction of debugging and upgrading is to make Xiaoyu's face move by itself, more lively, and even "dance".
Sanitize robot "Xiaosa"
"A little chubby doll with a mustache"
Compared with the lively and playful "Xiaoyu", the blue and white robot "Xiaosa" next to it is more special.
Wang Zongsen, a sophomore majoring in mechanical and electronic engineering, is the shape designer of "Xiaosa", and in his eyes, "Xiaosa is a little chubby doll tied with a mustache." ”
"The function orientation decided that Xiaosa needed to be short and fat, and it was originally designed to look like a rice cooker, but after several versions of debugging, it was determined to look like it now. Wang Zongsen introduced, "Xiaosa" chassis is wide, easy to load cleaning device, the body of the center is fat round, can bear the weight of the water tank and other devices. There is a smile emoji on the body, which is the "face" of the robot that smiles all the time. The spray device on the top is like a cupola mustache tied to a child, and although it looks short and fat, it is not bulky. "Thanks to the positioning of the cleaning robot, it looks cleaner in blue and white. If the height is less than 1 meter, it is considered that if the child sees it, it will be more relatable. ”
Li Rui, a sophomore majoring in electrical engineering and intelligent control, introduced that Xiaosa is a family intelligent sanitize robot with multi-functional integration of sanitize, cleaning, and inspection. In terms of program design, in addition to functional matching, more attention is paid to the ability to deal with emergencies, so as to further "free your hands" in subsequent application scenarios.

"Xiaosa" has a high degree of perception ability, and can realize autonomous navigation, autonomous movement, and autonomous obstacle avoidance in an unmanned environment, providing intelligent services for families, hospitals, schools and other scenarios. It can search the disinfection area independently, and quickly spray a large amount of atomized disinfectant for disinfection.
Industry-university-research efforts
The robot track helps intelligent manufacturing
"These two robots are the first batch of interactive robots independently developed by our Undergraduate Innovation Lab. Ye Chuan, a teacher at the Engineering Training Center of Nanchong Campus of Southwest Petroleum University, introduced that focusing on new productivity with scientific and technological innovation as the core is the focus of scientific research and innovation in colleges and universities. As a typical representative of new quality productivity, intelligent mobile robots show their skills in manufacturing, logistics, medical and other fields with their efficient, intelligent and flexible characteristics. For intelligent interactive service robots in home scenarios, it is a new track.
In 2023, the school's two works, "Innovative Design of Robot Based on Fisc" and "Path-guided Experiment of Structured Light 3D Scanning Imaging Robot", won the first prize of the China University Robot Experimental Teaching Innovation Competition.
Since then, the school's science and technology innovation laboratory has been preparing for an interactive robot research and development project. In the way that teachers lead students to form teams, do projects and bring talents. "Our students are concentrated in the sophomore and junior years, but in the process of research and development, we not only strengthen our professional ability, but also enhance our scientific research and innovation ability. ”
After more than 3 months of R&D and debugging, two robots have been formed, and two patents are being declared.

"We actively connect with enterprises, realize market transformation through the demand side, and on the other hand, look for support for the transformation of scientific and technological achievements, and make joint efforts to help intelligent manufacturing. Ye Chuan introduced that at present, these two robots are still being upgraded, and they will also inject more intelligent and more life scene functions.
"The cultivation of students' practical innovation ability is an important part of the school's talent training. Chen Guihui, vice president of Nanchong Campus of Southwest Petroleum University, introduced that the school proposed the practical teaching model of "one major, one brand" and "one competition for a lifetime", built and rebuilt 96 laboratories, and gave full play to the role of discipline competition in the cultivation of students' practical innovation ability, and continued to improve the quality of talent training. In the 2023 National College Student Competition List, Southwest Petroleum University ranked 16th in the country. In the list of winners of the national college student competition, the students of the Nanchong Campus of Southwest Petroleum University have won more than 200 national competition awards.
