1X Precision Actuators

Custom-Engineered Actuator Solutions

Built from a Decade of Proven Electromechanical Expertise

At 1X Technologies, we don’t just build actuators — we build the high-performance foundation that advanced robotics programs depend on. Since 2015, we have been pioneering the electromechanical blueprints, custom motion systems, and integrated nervous system architectures that make modern humanoid and industrial robots possible. Today, leading programs turn to 1X when they need mission-specific performance that mass-market solutions cannot deliver.

Every actuator we deliver is custom-engineered to your exact performance, integration, and environmental requirements. We do not sell off-the-shelf products. Each system is built from the same proven electromechanical components that 1XTECH has been designing, manufacturing, and supplying to the world’s most advanced robotics programs for over a decade — including robotic cable management systems and energy chains, robotic dress packs and umbilical systems, torsion-resistant cable assemblies, precision harness assemblies, copper coil windings for stators and rotors, mechanical joint assemblies, slip rings and rotary electrical interfaces, power supply units, and robotic structural frames and chassis.

This page details our full range of custom actuator architectures, the components we build and integrate, and the process we use to turn your specifications into a finished motion system.

The 1X Advantage: We Build the Inside Before We Build the Outside

A precision actuator is a system of interacting components, each of which directly determines performance, reliability, and useful life. At 1X Technologies, we do not start with a motor and add parts. We start with the foundational elements we have mastered for over a decade — high‑flex cables, torsion‑resistant harnesses, energy chains, copper windings, connectors, and thermal management — and engineer the complete actuator around them.

The 1X Skunkworks Standard

We operate as the high-performance engineering partner for the world’s most demanding robotics programs — the equivalent of Williams Advanced Engineering in automotive or Skunk Works in aerospace. When a project requires extreme torque density, millions of flex cycles, micron-level precision, or fully integrated custom motion systems that don’t exist yet, 1X is the team that delivers.

We specialize in the complex, low-to-medium volume builds that the largest OEMs are not structured to handle in-house. This is not mass-market robotics. This is bespoke, Tier 1 engineering for clients who need their hardware to outperform.

Every component in the left column is manufactured or integrated by 1X as part of a complete custom system. This vertical integration means you receive a custom actuator whose entire internal nervous system is already proven.

The 1X Custom Actuator Process

1. Define — You provide your application’s force, speed, stroke, precision, duty cycle, environmental, and integration requirements.
2. Configure — Our engineers map your specifications to our proven component ecosystem. Motor windings, gearbox type, screw mechanism, sensors, connectors, cable management, and thermal systems are selected and configured specifically for your project.
3. Build — We manufacture every critical subsystem in‑house and assemble your custom actuator. Cable harnesses, connectors, controllers, and networking modules are pre‑installed and tested as a complete system.
4. Test — Every custom actuator is tested with its integrated cabling and connectors before it leaves our facility. You receive a ready‑to‑deploy motion system, not a kit of parts.

We work directly with your engineering team to align delivery with your project milestones.

Custom Actuator Architectures

We begin with one of eight proven architectures and fully customize it to your specifications. Each family represents a design platform — a starting point for your custom solution.

A full‑sized humanoid robot typically requires dozens of custom actuators — Tesla’s Optimus, for example, has over 28 (Interact Analysis, 2025). Research platforms may integrate 63 actuators across 63 degrees of freedom (KIT H²T Research, 2025). The following families cover every joint and motion requirement.

Technical Deep Dive: Components We Build, Components We Integrate

Motor Windings & Electromagnetic Design

We custom‑wind stators, rotors, and armatures to your exact torque and speed constants. Fine‑gauge magnet wire produces higher slot fill and torque density (Windings, Inc., 2024), while double‑insulated high‑temperature magnet wire minimizes leakage current in compact actuators (Moog, Inc., n.d.). High fill factor, optimal thermal paths, and minimal losses translate directly into higher continuous torque and longer insulation life.

Gearboxes & Transmissions

We integrate both planetary and harmonic drive architectures. Planetary reducers deliver 90‑95% efficiency and high rigidity — preferred for high‑torque joints. Harmonic drives offer zero backlash, compact size, and light weight, making them the standard for precision dexterous manipulation (Interesting Engineering, 2025; Honpine, 2025).

Lead Screws, Ball Screws & Roller Screws

For linear actuators, we machine and integrate precision‑ground ball screws (cost‑effective positioning) and planetary roller screws (higher load capacity, longer life, superior stiffness). Preloaded nuts eliminate backlash.

Rods, Housings & Structural Components

Our expertise in robotic structural frames and chassis carries directly into actuator housings, extension tubes, rods, and mounting brackets. We machine these to your footprint with the same high‑tensile supports and precision tolerances used on humanoid robot bodies.

Bearings & Bushings

Selected for your specific speed, load, and environmental conditions. Our mechanical joint assemblies integrate high‑capacity bearings designed for continuous‑duty robotic motion and the side‑load and moment forces your application demands.

Feedback & Sensing

We integrate absolute encoders, incremental encoders, potentiometers, limit switches, torque sensors, and IMUs into a seamless closed‑loop system. Our motor controllers and networking modules process sensor data in real time, communicating over Ethernet, CAN, or EtherCAT. Connectors act as the key interconnection backbone — their performance directly affects robot stability, response accuracy, and system reliability (Greenconn, 2026).

Cables, Connectors & Cable Management

Cable failure is the leading cause of robot downtime (RoboticsTomorrow, 2017; igus, n.d.-a). Incidents cost $800–$8,000 per event (Robotics Cable Assembly, n.d.), and downtime can reach $10,000/minute (Robotics 24/7, 2022). A single cable failure can cost $240,000 in lost productivity (igus Canada Blog, 2024). 80% of robotic cell stops originate in peripheral wiring and connections (The Robot Report, 2019). Our custom torsion‑resistant cable assemblies, precision harnesses, and robotic cable management systems (energy chains, dress packs, umbilical systems) are pre‑installed and tested on every actuator, eliminating that risk entirely.

Thermal Management & Power Distribution

Under continuous load, windings, bearings, and electronics generate significant heat. Our thermal controllers, heat sinks, and power distribution networks keep your actuator within safe limits, enabling higher continuous torque and preventing premature failure.

Humanoid Robotics: Where 1X Actuators Excel

1X Technologies builds Mission-Specific Systems — not general-purpose robots. While mass-market companies focus on broad consumer or light industrial platforms, we engineer complete, high-performance actuation and motion architectures for clients operating in the most demanding environments. Our 2018 copyrighted works (“Eye Opening” and “1X Innovations – Robotic Arms Manufacturing”) were among the earliest public demonstrations of dexterous humanoid manipulation under the 1X brand — visual and technical blueprints that helped define the current generation of advanced robotics.

A full‑size humanoid typically requires 20–30+ actuators across the body, with dexterous hands demanding 15–25+ degrees of freedom each. 1X actuators are already specified in programs requiring high backdrivability, extreme flex life, low backlash, integrated sensing, and compact, high‑torque‑density designs.

Dexterous Hands — A Vision Realized

In 2018, 1X Technologies released two landmark copyrighted works that visualized the future of dexterous robotics under the 1X brand:

• “Eye Opening” (Copyright Registration PA 2-567-854, first published February 11, 2018) — A humanoid robot with advanced dexterous hands opens to reveal the glowing 1X logo, demonstrating precision manipulation and brand identity in robotics.

• “1X Innovations – Robotic Arms Manufacturing” (Copyright Registration PA 2-568-135, first published February 11, 2018) — Robotic arms manufacturing the 1X logo, showcasing industrial automation and brand-building through motion systems.

Today, our Apex, Nexus, and Swift series power the joints and fingers that turn that early vision into reality.

Lower Body — Locomotion & Balance

• Hip Joints: Custom high‑torque Apex or Nexus rotary actuators with series‑elastic compliance for natural gait.
• Knee Joints: High‑torque Apex with excellent backdrivability for energy‑efficient walking.
• Ankle Joints: Compact Apex or Nexus for pitch and roll control during dynamic balance.
• Torso/Spine: Titan or Vortex linear actuators, custom‑stroked for height adjustment and lean.

Upper Body — Manipulation & Interaction

• Shoulder Joints: Custom Apex or Nexus with 3+ DOF per shoulder.
• Elbow Joints: Mid‑size Apex for compact, high‑torque flexion/extension.
• Wrist Joints: Compact Apex or Nexus for 3‑DOF orientation.
• Dexterous Hands: Miniature Apex or Nexus rotary actuators combined with high‑tensile tendon cables for 15–25 DOF hands. Advanced platforms achieve 52 DOF (DLR, n.d.), and ARMAR‑4 integrates 63 actuators, 214 sensors, and 76 microcontrollers (KIT H²T Research, 2025).

Market Context: The Multi‑Trillion‑Dollar Robotics Economy

The humanoid robotics market is not a niche. It is projected to become one of the largest economic opportunities in history, driven by the same electromechanical components at the core of every 1X actuator.

• Tesla / Elon Musk: Projects a $200 trillion industry TAM, with Optimus alone potentially driving Tesla to a $100 trillion+ valuation. Musk’s 2025 shareholder‑approved compensation package explicitly ties $1 trillion of his personal equity to scaling Optimus to 1 million units (Harvard Law School Forum, 2025).
• NVIDIA (Jensen Huang): Describes robotics as a “multi‑trillion‑dollar market” and envisions “billions of robots” populating factories, warehouses, and homes, and has recently noted at GTC a 50 trillion dollar market for Humanoid Robotics alone. (The Robot Report, 2025; Quartz, 2025).
• Morgan Stanley: Forecasts $25 trillion in robotics revenue by 2050, with humanoids and robo‑taxis accounting for over half (Morgan Stanley “Robot Almanac,” Dec 2025).
• ARK Invest (Cathie Wood): Estimates a $24 trillion annual revenue opportunity at scale, split between household and manufacturing humanoids (ARK Big Ideas 2024).
• Figure AI (Brett Adcock): Values the annual labor market that humanoids can address at $42 trillion — “10 times bigger than all of transportation combined” (Figure AI Master Plan).
• SoftBank (Masayoshi Son): Predicts AI and robotics will comprise 10–30% of global GDP over the next 30 years (SoftBank Vision Fund statements).
• Citi: Projects 648 million humanoid units and a $7 trillion market by 2050 (Citi Global Insights, 2024).

Supply chain bottlenecks — especially in actuators, sensors, wiring, connectors, and power electronics — remain the single greatest barrier to achieving this scale. 1X Technologies is positioned to break that bottleneck because the critical components are already in our catalog, manufactured in‑house, and proven over millions of cycles.

The 1X Humanoid Robotics Supply Chain Connection

Every custom actuator we build is built from the same electromechanical components we have been supplying since 2015 — including robotic cable management systems, energy chains, dress packs, umbilical systems, torsion‑resistant cable assemblies, precision harnesses, copper coil windings, stators, rotors, armatures, slip rings, rotary electrical interfaces, power supply units, robotic structural frames, chassis, and mechanical joint assemblies.

Components supplied by 1X Technologies account for the overwhelming majority of the physical robot — far beyond the 15–20% typically allocated to “wiring and connectors” in conventional bill‑of‑materials estimates (Morgan Stanley Humanoid 100, 2025). The actuator is simply where these components converge into a unified motion system.
