A smart robot dog is a quadruped robot that imitates the movement patterns of dogs. It combines mechanical structure, sensors, artificial intelligence (AI), and automatic control technology to be able to walk autonomously, avoid obstacles, perform tasks, and even interact with humans. It is one of the most representative applications in the field of robotics. The following is an introduction from the aspects of functions, technology, application scenarios, and representative products: Functional Features Flexible Movement: Some smart robot dogs have improved joint performance and can perform actions such as jumping, rolling, pouncing, dancing, handstands, and sitting, with a maximum running speed of 5m/s or even higher. For example, Unitree's robot dogs can make heart shapes, shake hands, roll over, and act cute during events, with very flexible movements. Environmental Perception and Interaction: The head is equipped with a 4D vision module that can accurately recognize faces and gestures; built-in advanced AI algorithms can analyze environmental data and make corresponding responses. For example, the inspection robot dog "Yu Xiaoye" has a high-definition camera that can scan crops in greenhouses in detail, and environmental collection sensors can monitor temperature, humidity, light, and carbon dioxide concentration in real time, and accurately analyze crop growth status based on crop growth models. Emotional Interaction: It has an emotional interaction module that can perceive human emotions and simulate personality traits, achieving emotional interaction and emotional feedback. For example, KODA robot dogs can perceive human emotions such as joy, anger, sorrow, and happiness, achieve emotional interaction and emotional feedback, and coexist with humans in the form of living beings. Technical Architecture Drive Technology: Electric drive is used, with high control accuracy, fast response speed, and low noise. The bionic limbs are equipped with high-precision servo motors, giving the robot dog agile posture. Sensor Technology: Equipped with various sensors, such as 4D ultra-wide-angle lidar, multispectral cameras, environmental collection sensors, etc., to achieve environmental perception and precise positioning. Artificial Intelligence Technology: Integrated with visual, auditory, tactile, and olfactory sensors, through deep learning and algorithm optimization, it achieves autonomous navigation, task execution, and intelligent interaction...
