One thumb. Three fingers.
Every machine you build.
A field-serviceable manipulator that mounts onto Titan 0000, Titan 88, Titan 1111, or any third-party arm with an ISO-9409 flange. Mechanically capped grip force, multi-modal contact, drone-grade payload — engineered around what Titan Core OS actually needs to drive.
Five motors driving four digits — one thumb, three fingers, underactuated
Mechanically capped per finger — the ceiling is geometry, not software
Brake-locked grip at near-zero power — indefinite hold, any platform
Wrist-mounted actuation keeps the fingertip light — drone-grade payload
Built to do the work, not to impress the lab.
Force ceiling enforced by physics
Grip force is bounded by spring geometry, not firmware. The ceiling — 80 N per finger on the Safe variant, 200 N on Industrial — is a property of the mechanism. ISO/TS 15066 compliant by construction. The safety claim survives every software state.
Three contact modes, one end-effector
Electric tendon for primary grasp. Pneumatic air-puff for non-contact button press. Palm vacuum for small-object lift. Titan Core OS selects the physical principle per task. Air is supplied platform-side — passive cartridge on aerial, compressor or shop air on ground.
Adaptive grasp without programming
A single command closes the hand; each finger conforms to the object passively through tuned tendon pulleys at every joint. Six of the eight cataloged grasp primitives — pinch, tripod, hook, power, lateral, palmar — covered without per-object planning.
Indefinite hold at zero watts
An electromagnetic brake engages on the capstan after two seconds of stable grip. The motor powers off; the grip holds mechanically. Battery-powered platforms can grip a tool, a railing, or a payload for an hour without measurable power draw.
Per-unit calibration, precision-grade output
Every hand ships with a firmware calibration table — spring rates, motor constants, joint friction, tendon stretch — measured at end-of-line. Titan Core OS compensates for the variation in real time. The output is precision; the cost is not.
Field-replaceable everything
Tendons swap in under fifteen minutes. Springs in under five. Silicone fingertip pads in under two. Motor and brake modules pull from the wrist housing as sealed cartridges. Operations don't stop for service.
Five motors. One brake stack. One spring per finger.
Actuation lives in the wrist housing — out of the fingertip, off the inertia budget, into a serviceable cartridge. Tendons run through Bowden sheaths to each finger. Series-elastic springs sit in the force chain as the mechanical ceiling. Electromagnetic brakes hold grip indefinitely at zero power.

Across the fleet. Across the field.
Defense — Interior Clearance
Door handles, light switches, contraband bagging in human-built structures. Mechanical force ceiling matters when soldiers operate alongside the platform.
Industrial Intervention
Valve operation, switchgear, sustained tool grip in austere conditions. Holds the tool through power transitions; never drops it.
Last-Mile Delivery
Packages, doorbells, gate operation at the dropoff. Air-puff variant rings a bell or presses a buzzer from five centimeters — no precision alignment required.
Aerial Response
Mid-air button press without landing. Light-payload retrieval via palm vacuum. Sensor placement on remote infrastructure. Thousands of pneumatic actuations per cartridge.
Agriculture & Fieldwork
Gate operation, irrigation valve control, equipment interfaces. Adaptive grasp handles irregular handles and rope without bespoke programming.
Hardware enforces the safety floor.
Software earns the ceiling.
Complexity is often mistaken for capability. Titan 1T3F takes a different line. Vision does the contact estimation; calibration absorbs the tolerances; a small mechanical brake replaces continuous motor torque. What Titan Core OS delivers in software, the hardware doesn't have to carry. The mechanism stays light, serviceable, and ready for the field — the autonomy does the rest.
Titan 1T3F is currently in active design. Specifications reflect engineering targets and may evolve as prototyping advances.
