XLeRobot-Pro
Mobile Bimanual Manipulation Robot
Developed an untethered, low-cost bimanual mobile manipulator featuring a custom Tri-Bus power topology and structurally optimized chassis to support GPU-accelerated edge compute.
The Problem
Cutting the Cord
Open-source robotics lowered the barrier to entry — but true untethered deployment breaks on integration.
- Compliant 3D-printed links waste motor torque.
- Actuating a 17-DoF system at once collapses bus voltage under transient load, causing unpredictable compute brownouts mid-task.
The Approach
Tri-Bus Power & Structural Optimization
A custom Tri-Bus power topology with firmware-level current envelopes isolates the onboard NVIDIA Jetson Orin Nano from the drivetrain's dynamic loads — physically and logically.
- +67% end-effector payload from a functionally graded "High-Shell" print strategy.
- Zero-latency autonomy for VR teleoperation and learning-based policy execution.
