Hardware Components
Key system architecture and the complete Bill of Materials (BOM).
System Architecture
XLeRobot-Pro is designed to be fully untethered, balancing compute power with battery efficiency.
Tri-Bus Power Topology
Isolates high-transient motor loads from the Jetson Orin Nano, completely eliminating power brownouts during aggressive maneuvers.
Embedded Autonomy
NVIDIA Jetson Orin Nano Super provides full onboard GPU compute. No external PC tethering required for VLA models.
Robust Perception
Intel RealSense D435 RGB-D camera enabling high-fidelity SLAM navigation and vision-based bimanual manipulation.
Optimized Structure
Functionally graded 3D-printed links utilizing High-Shell topology to achieve maximum stiffness-to-weight ratio.

* Note: The sum of the listed items is $1,247.27. The 3kg of PLA filament ($45.00) is included in this BOM for reference but is calculated as a general lab consumable rather than a direct platform cost, bringing the official total to $1,202.27.
3D-Printed Structure
About 90% of the chassis, arms, neck, and base are 3D-printed. The BOM above covers the filament; download the combined 3MF below.
On the GitHub page that opens, click the “Raw file” button (top-right of the file viewer) to download the .3mf.
Recommended: Bambu Lab A1 or Prusa i3 MK4 printing PLA Matte Black, with PETG HF / PLA CF as optional strength upgrades and TPU95A for soft finray fingers. Full print settings, build order, and assembly steps are in the Build Guide.
Hardware/Software Interface
Ensure your driver boards are properly recognized by the compute node before proceeding to calibration.
