A Smart, Scalable Companion for STEM Education
NavBot-EG01: An 8-DOF Desktop Quadruped Robot Dog Designed for STEM Education
Simple · Clear · Understandable · Buildable
The NavBot-EG01 is an 8-degree-of-freedom (8-DOF) desktop quadruped robot dog, purpose-built for STEM education in middle schools, high schools, and vocational institutions. Centered on the philosophy of “helping students truly understand how robots move and think,” it simplifies mechanical complexity to emphasize core learning principles, enabling hands-on exploration of programming, engineering, mathematics, and introductory AI.
Unlike high-DOF research platforms, the NavBot-EG01 adopts a streamlined 2-DOF per side leg design (total 8 DOF) — front legs control forward/backward swing and lift, while rear legs use simplified planar motion. This balanced structure maintains basic walking capability while significantly reducing control complexity, making it ideal for beginners to learn joint coordination, gait generation, and balance control.

Where Innovation Meets the Classroom
Motion control system designed for learning
At the heart of NavBot-EG01 is the philosophy: “Every step should be understandable.” Instead of chasing high performance, it emphasizes clarity in movement logic and programmability.
Basic Gaits Supported: Trotting, turning in place, forward/backward walking
Step-by-step Learning Path: From single-leg movement → bilateral coordination → full-body gait generation
Visual Debugging Tools: Real-time display of joint angles, center of gravity, and gait timing diagrams via PC interface
Expandable Feedback Control: Built-in support for MPU6050 IMU sensor to enable balance control experiments (optional)
Programming for Every Skill Level
NavBot-EG01 supports various programming methods, enabling learners at all levels to start from scratch and grow progressively—true “zero to mastery” learning.
Modular by Design, Built to Grow
Featuring a modular architecture, this robot includes swappable components such as motors, sensors, and control boards. Students can disassemble, reconfigure, and expand the system to match lesson objectives or personal interests. It’s a flexible learning platform that grows with the user.
Hands-On Learning with Real Impact
Students can program behavior, adjust movement, and explore physics and engineering principles through real-time control. By turning code into action, they gain practical experience in logic, mechanics, and digital problem-solving.
Built-In Safety and Classroom Durability
From its low-voltage operation to child-safe structure and rugged materials, the robot is engineered for frequent educational use. It’s built to withstand countless experiments while keeping students safe and confident as they learn.
Cross-Disciplinary Exploration
This is more than just a robot—it’s a launchpad into multiple disciplines. As students engage, they connect knowledge across physics, math, computer science, and engineering. It supports integrated learning and prepares them for the challenges of tomorrow.
Teamwork, Creativity, and Innovation
Project-based learning and collaborative tasks encourage students to think like engineers and innovators. From idea to implementation, learners work in teams to solve problems, share insights, and bring their robotic designs to life.
Why It Matters: Learning That Lasts
NavBot-EG01 is more than a teaching tool — it’s a catalyst for deeper engagement, stronger skills, and future-ready learning. By combining theoretical knowledge with practical exploration, it brings STEM subjects to life in ways that stick. Whether you’re an educator seeking to energize your curriculum or a student ready to build, this robot opens doors to discovery and innovation—one project at a time.
