Quadruped Robot Dog
Build a four-legged robot dog capable of dynamic walking, running, and adaptive terrain navigation using advanced kinematics and gait control.
Project Overview
Quadruped robots represent a significant step up in complexity from wheeled platforms, requiring: - Multi-leg inverse kinematics - Gait planning and coordination - Balance and stability control - Terrain adaptation
What You'll Build
- Assemble a quadruped robot chassis with 12+ servo motors (3 per leg)
- Implement inverse kinematics for leg control
- Develop gait patterns (trot, walk, gallop)
- Add IMU sensors for balance feedback
- Integrate autonomous navigation with ROS 2
Required Knowledge
- Advanced robot kinematics (forward/inverse for multi-joint systems)
- ROS 2 control architecture
- C++ or Python for real-time control loops
- 3D printing for custom parts
- PID control and sensor fusion
Popular Platforms
- Stanford Pupper: Open-source, affordable quadruped
- Spot Micro: 3D-printable Boston Dynamics Spot replica
- Unitree Go1/A1: Commercial platforms with SDK
Key Challenges
- Coordinating 12 motors simultaneously
- Real-time gait computation
- Power management (quadrupeds draw significant current)
- Shock absorption and mechanical durability
