9 DOF Metal Quadruped Robot Bionic Mechanical Dog with Structural parts without Servo

Quadruped Robot / Bionic Mechanical Dog 9DOF Robot Dog Kit Structural Parts DIY (Without Servo)

This high-quality robot dog kit is designed for robotics learning, prototyping, and research. The Quadruped Robot / Bionic Mechanical Dog 9DOF Structural Kit features a durable 2 mm hard aluminium alloy frame, offering excellent strength, lightweight performance, and a premium bionic structure that closely resembles a four legged robot. Each leg supports 2 servo mounting positions, plus one extra for the head, enabling a realistic robot dog kit motion system with a total of 9 Degrees of Freedom (9DOF). This allows smoother quadruped walking postures and dynamic movements similar to robotic pets and four-legged mechanisms. This kit contains only the structural parts (no servos or controller included), giving you complete flexibility to choose your own servo motors and control board — such as Arduino, STM32, ESP32, Raspberry Pi, or a dedicated servo controller. As a result, it becomes the perfect platform for robotics, AI-based gait research, and advanced quadruped control techniques.
