NavBot-D1 Quadruped Robot

NavBot-D1 is a fully open-source quadruped robot built on an all-aluminum CNC frame. Engineered for researchers, robotics teams, and serious developers, it ships with the latest reinforcement-learning locomotion stack, NVIDIA Jetson edge compute, and a four-channel control suite that scales from desktop Wi-Fi to long-range LoRa and Starlink. Every mechanical part, every electronic interface, and every line of control software is documented and shareable — no black boxes.

Built in Texas. Open by design. NavBot-D1 is part of NavBot's commitment to transparent, reproducible robotics — bring it home, take it apart, study every joint, fork the firmware, and build the future of quadruped robotics with us. github.com/fuwei007/NavBot-D1

Why NavBot-D1

• 100% open hardware — STEP files, CNC drawings, sheet-metal patterns, fiberglass board layouts, and complete BOM (motors, joint supports, leg parts, body shells) are all released. Manufacture spares, customize the chassis, or fork the design.
• All-aluminum aerospace-grade frame — CNC-machined hip and knee joint supports, sheet-metal upper/lower body, dual aluminum battery enclosures, and reinforced aluminum tube linkages. Built to survive lab work, field testing, and outdoor missions.
• Modern reinforcement-learning gait — locomotion controller trained with the latest sim-to-real RL pipeline. Smooth walking, trotting, recovery from pushes, and adaptive footing on uneven terrain.
• Heavy-duty payload — 25 kg payload capacity. Mount thermal cameras, LiDAR, manipulator arms, or industry sensors directly to the frame.
• Four control channels — Wi-Fi, ROS 2 / RC transmitter, LoRa, or Starlink. Pick the right radio for the mission.

Control & Communication

Standard onboard radio includes LoRa long-range telemetry, integrated GPS, and a video transmission module for real-time first-person streaming.

Compute & Sensing

• NVIDIA Jetson edge AI compute on a custom carrier board — ample headroom for vision, SLAM, and on-device inference
• Inertial sensing — high-rate gyroscope with USB-to-CAN bridge for joint telemetry
• Onboard FPV video transmitter for low-latency operator video
• GPS module for outdoor waypoint navigation

Mechanical Specifications

Expandable Payload Options

NavBot-D1 is designed as a modular sensor and tool platform. The all-aluminum frame and standardized RJ45 / USB 3.0 interfaces make integration straightforward.

• Thermal imaging — clip-on thermal sensor module, mounts to the upper frame
• LiDAR — 2D / 3D LiDAR units connect directly to the mainboard via RJ45 or USB 3.0
• Robotic claw / gripper — pick-and-place manipulator, wired through RJ45 or USB 3.0; standalone grippers also supported
• Custom payloads — up to 25 kg, mounted via the standard top deck mounting pattern

Open-Source Resources

Every part is documented. Buyers and the community get:

• Full mechanical CAD: STEP files for all 12 leg components, body shells, joint supports, and battery enclosures
• CNC machining drawings (PDF) for direct quoting at any precision shop (e.g., JLCMC reference pricing included in the BOM)
• Complete bill of materials — motors, sheet metal, fiberglass boards, aluminum tubing, fasteners, bearings — with vendor references
• Reinforcement-learning locomotion stack and ROS 2 control nodes
• Schematic for the carrier board, gyro / USB-to-CAN bridge, LoRa + GPS module, and video transmission module

Availability & Pricing

Pre-order units are limited and produced in small batches. Each unit is hand-assembled, tested, and calibrated in our Texas lab before shipping.
