The Multi-Joint Control Unit is the central nervous system of Ludu 3 — and it can be the brain of your robot too. It merges high-level AI compute with hard real-time joint control on one board set.
Architecture
- Main compute: Intel NUC i7-1370P or RK3588, with optional NVIDIA Jetson Thor for on-board AI
- Real-time control: AMD Artix-7 XC7A50T FPGA
- Imaging: HiPNUC IMU for attitude estimation
- Capacity: 60+ joints controlled at 1,000 Hz
Why FPGA matters
Walking balance, compliant contact and fast recovery all depend on control loops that never miss a deadline. The Artix-7 FPGA keeps the 1 kHz joint loop deterministic even while the main CPU runs perception, speech or your business logic — a separation that software-only controllers cannot guarantee.
An open software stack
The unit runs Ubuntu 22.04 and exposes the full stack: CAN FD MIT protocol for joints, ROS 2 drivers, the RL training framework and URDF models. ODM customers receive documentation and hands-on support, so your team can build on it from day one.
