Smart robot dogs are quadruped robots that mimic canine locomotion. They combine mechanical structures, sensors, artificial intelligence (AI), and automatic control technology to walk autonomously, avoid obstacles, perform tasks, and even interact with humans, representing a significant application in the field of robotics. The following introduces them from aspects of functions, technology, application scenarios, and representative products: Functional Features Flexible Movement: Some smart robot dogs have enhanced joint performance, capable of executing actions like jumping, rolling, pouncing, dancing, handstands, and sitting, with maximum running speeds of 5m/s or even higher. For example, Unitree's robot dogs can make hearts, shake hands, roll over, and act cute during events, demonstrating remarkable agility. Environmental Perception and Interaction: The head is equipped with a 4D vision module for precise facial and gesture recognition. Advanced AI algorithms are built-in to analyze environmental data and respond accordingly. For instance, the inspection robot dog "Yu Xiaoye" uses a high-definition camera to meticulously scan crops in greenhouses, while environmental sensors monitor temperature, humidity, light, and CO2 concentration in real-time, accurately analyzing crop growth status based on growth models. Emotional Interaction: Features an emotional interaction module that can perceive human emotions and simulate personality traits, enabling emotional interaction and feedback. For example, KODA robot dogs can sense human emotions like joy, anger, sorrow, and happiness, facilitating emotional interaction and feedback, coexisting with humans as living beings. Technical Architecture Drive Technology: Utilizes electric drive for high control precision, fast response speed, and low noise. Bionic limbs are equipped with high-precision servo motors, granting the robot dogs agile posture. Sensor Technology: Equipped with various sensors, such as 4D ultra-wide-angle LiDAR, multispectral cameras, and environmental collection sensors, to achieve environmental perception and precise positioning. Artificial Intelligence Technology: Integrates visual, auditory, tactile, and olfactory sensors. Through deep learning and algorithm optimization, it achieves autonomous navigation, task execution, and intelligent interaction...
