1. The entire machine has 12 degrees of freedom, with a multi-link structure design for the legs, which increases the effective torque of the servo motors2. It uses 2.3kg.cm serial bus servos, which can provide real-time feedback on position, speed, and input voltage, etc3. A real-time operating system serves as the lower-level machine for gait generation and link inverse solution, relieving the computing burden of the upper-level machine and improving the efficiency of gait calculation4. The ultra-compact structure design can be used on a desktop, with the structure made of aluminum alloy and HP nylon materials, reducing weight while maintaining structural strength5. The Raspberry Pi can be expanded as the upper-level machine, using OpenCV-related advanced functions. The routine includes face detection, motion detection, and color tracking functions. It reserves expansion interfaces and comes with rich user manuals and secondary development documents6. It has attitude self-balancing, with a high-precision 9-axis motion tracker ICM20948 that can adapt to various terrain environments and control its own balance7. Login to the Web to remotely control, without the need for manual configuration of the compilation environment. The machine starts up and automatically establishes a Wi-Fi hotspot. It can be connected and logged into the control page using a mobile phone or computer browser, without the need to download an app8. It can record actions and perform one-click playback. The robot dog can save the control robots JSON instructions as a task file, which is saved in the Flash of the ESP32 and will not be lost after power loss. The robot dog can execute complex repetitive operations by calling these task filesParameters1. Standing: length 218mm, width 116mm, height 152mm2.
