Surgical Robotics

29×

faster than da Vinci — the most advanced surgical robot on Earth

The Problem

The best surgical robot runs at 100 Hz.
The human hand shakes at 12 Hz.

The da Vinci Surgical System — used in 1.5 million procedures per year — operates with a 10ms control loop. That's the industry best. Every competitor is slower. Mutex locks serialize sensor reads, planning, and haptic feedback, introducing jitter that limits tremor compensation and makes remote telesurgery clinically unsafe.

The Tremor Problem

The surgeon's hand shakes at 12 Hz.
We sample it 2,600 times per cycle.

Human physiological tremor oscillates at 8–12 Hz. At 100 Hz control frequency, da Vinci samples tremor roughly 8–12 times per oscillation cycle — barely enough to detect it. At 31,250 Hz, we sample the same tremor 2,600 times per cycle. The correction happens before the motion reaches the instrument. The shake never reaches the patient.

Telesurgery

A surgeon in New York.
A patient in Lagos.

Telesurgery requires total round-trip latency under 200ms to be safe. Network physics contribute ~150ms — that can't be changed. Every existing surgical robot adds another 10–50ms of compute on top, pushing total delay past the safety threshold. Our architecture adds 0.34ms. Total round-trip: 150.7ms. Remote surgery becomes clinically viable — not someday, now.
