Three layers,
owned end to end

From custom silicon drivers and hard real-time RTOS to whole-body MPC and multimodal perception models. We control every layer of the stack.

02. Autonomy loop

From photon
to torque

Every 5 milliseconds (200 times a second), the machine reads the ground, solves contact dynamics, and commands joint torques.

01

Perception

Solid-state lidar points and stereo RGB-D streams are fused into a local 5 cm elevation map in 4.2 ms.

02

Contact planning

Candidate footholds are scored for friction, slope, and structural integrity.

03

Whole-body MPC

Quadratic programming solver generates optimal ground reaction forces for centroidal stability.

04

Torque dispatch

Target joint currents are streamed to local SEA/QDD motor inverters over isolated 1 kHz fieldbus.

03. Safety

What happens
when it fails

Robots operating in complex terrain must fail safely. Our architecture guarantees fail-closed behavior across power loss, communication drops, and sensor blinding.

Triple watchdog

Isolated hardware supervisor board monitors MPC heartbeats. If the main compute hangs for >15 ms, the safety controller initiates a soft collapse pose.

Mechanical brakes

Spring-applied electromagnetic holding brakes on knee and hip pitch joints instantly engage upon DC bus under-voltage, locking joints before gravity drop.

Thermal derating

Winding temperature estimators proactively adjust peak torque envelopes to prevent sudden thermal shutdowns during high-demand climbs.

04. Validation

Every surface we
have broken on

Simulation is necessary, but physical hardware only gets honest in the dirt.

Monsoon Mud & Roots

Tested shear limits on saturated laterite soil and slick root tangles.
