About this item
- TRUE RESEARCH ACCESS: unlocked firmware, raw 1 kHz joint telemetry and EtherCAT external control let your lab run its own whole-body controllers.
- 60 TRANSPARENT-TORQUE JOINTS: low-friction quasi-direct-drive actuators expose accurate torque estimates essential for learned locomotion and contact-rich manipulation research.
- SIM-TO-REAL, MINIMIZED: system-identified MuJoCo and Isaac Sim models with per-unit calibration reports shrink the reality gap dramatically.
- 400 HZ WHOLE-BODY CONTROL: hard real-time loop with deterministic latency supports aggressive dynamic behaviors, from running gaits to recovery stepping.
- LAB-READY PACKAGE: gantry mount, e-stop pendant, spare covers and priority engineering support are included with every hand-assembled unit.

Product description
The Stride S3 is Lumen Robotics' no-compromise research platform, built for labs pushing the frontier of locomotion, whole-body control and learned policies. Sixty transparent-torque joints expose raw current, position and temperature telemetry at 1 kHz, with a hard real-time 400 Hz whole-body control loop that accepts external controllers over EtherCAT. Unlike closed commercial platforms, the S3 ships with full state access and no locked firmware layers. Validated MuJoCo and Isaac Sim models with system-identified parameters mean policies transfer from simulation with minimal reality gap, and the included gantry mount and e-stop pendant support safe early experiments. Each S3 is hand-assembled and factory-characterized; a signed calibration report documenting joint friction, backlash and inertial parameters accompanies every serial number. Availability is limited to small batches.
