Precision Sensing for Robotics
Patented 2D absolute encoders that eliminate calibration, shrug off contamination, and deliver sub-micron accuracy — across every joint and every axis.
Why PreciLabs
Engineered to Eliminate
Every Error Source
Mechanical backlash, calibration drift, contamination, control latency — we didn't mitigate them. We architected them out at the silicon level.
Zero Mechanical Error
Gears have backlash. Limbs flex under load. Our 2D sensor goes beyond standard rotation, measuring multi-dimensional off-axis deflection. Feed your AI the exact sub-micron data needed to digitally erase physical imperfections across any joint.
Zero Calibration
Micrometer alignment kills assembly speed. We eliminated it. Our ASIC dynamically calculates out eccentricity and mounting gaps on the fly. Bolt it on and power it up. Absolute positioning is instant—no homing runs, no drift.
Zero Degradation
Oil smears. Grease blinds. Our patented 2D optical code is immune. Built with extreme redundancy, it shrugs off heavy industrial contamination and over 60% physical scale damage without missing a single pulse.
Zero Control Lag
Humanoid balance requires hyper-fast proprioception. We deliver ultra-low latency, high-bandwidth absolute data directly to your motor drives. Execute the flawless, high-frequency control demanded for rapid locomotion and needle-threading dexterity.
Technology
Beyond Encoder Limits
Our patented optical sensing platform redefines what an encoder can do — breaking through the speed-resolution-size triangle that constrains conventional solutions.
Patented 2D Absolute Codes
A fundamentally new encoding principle that captures absolute position in two dimensions simultaneously — enabling capabilities impossible with conventional 1D approaches.
Firmware-Programmable SoC
A general-purpose encoder system-on-chip that can be configured in firmware, much like an image sensor paired with a processor — adaptable to a wide range of sensing scenarios.
Sub-Micron Precision
Nanometre-class repeatability and sub-micron accuracy across multiple axes, achieved at very high sampling rates for real-time closed-loop control.
Built-In Error Resilience
Redundancy, error detection and correction are inherent to the 2D code structure, enabling the highest safety integrity levels even under harsh operating conditions.
Contamination & Wear Immunity
The sensing method tolerates massive obstruction of the code pattern — oil, dust, scratches and ageing are absorbed without degradation of output quality.
Multi-Axis & Multi-Domain
The same core technology extends from rotary encoders to linear, 3D and 6-DOF applications, using a variety of optical configurations — shadow, reflective, transmissive and more.
Product
PreciSen™ Patented 2D Encoder
A highly optimized ASIC for absolute multi-dimensional sensing. Factory calibration eliminated at the silicon level.
Dynamic Compensation
Real-time eccentricity compensation from 2D (X,Y) positions completely eliminates factory calibration. Accuracy up to 14-bit over wide eccentricity ranges. No external reference or constant speed required.
Contamination Immunity
Full functionality maintained under massive real-world contamination — over 60% field-of-view obstruction absorbed without losing precision. Oil, grease, and heavy markings are irrelevant.
Extreme Mechanical Tolerance
±2 mm linear variation (X, Y, Z) and ±2.5° angular variation (tilt & twist) — 4× the range of competing encoders. Ideal for imprecise mounting and high-vibration dynamic environments.
Maximum Integration & Performance
Low BOM cost thanks to high level of ASIC integration and patented processing. Sampling rates fully compliant with the demanding requirements of robotic applications. SPI, I²C, BiSS, SSI interfaces built in.
Ready for Your Application
Firmware-programmable and highly adaptable, PreciSen™ fits a broad range of applications out of the box — and can be fine-tuned to your specific requirements with minimal effort.
Seamless Integration
Drop PreciSen™ into your actuator stack with straightforward mechanical mounting, optical alignment, and firmware configuration — no custom silicon or lengthy NRE cycles required.
Application-Specific Tuning
Higher speed for a hip joint, finer resolution for a hand, or multi-turn for a torso? Firmware programmability lets you tailor performance to each use case without hardware changes.

Applications
Built for Demanding Domains
From high-speed robotics joints to nanometer-class metrology, PreciSen™ adapts to the precision requirements of every axis and every environment.
Hollow-Shaft Rotary
Bearing-less kit encoder for hollow-shaft motors — ideal for robotics joints where cables and utilities pass through the centre. Up to 23-bit precision with real-time eccentricity compensation.
End-of-Shaft Rotary
Compact end-of-shaft configuration using rotating mirror or LED readhead. 19–20 bit precision — perfect for servo drives and actuator feedback.
Hexapod & Multi-Axis Platforms
Simultaneous 3D–6D position sensing at 50 µs cycle time. Sub-micron precision enables closed-loop hexapod control for semiconductor lithography, telescope alignment, and precision assembly.
Metrology & Linear Stages
26-bit/m linear precision with ~1 µm point-to-point accuracy on scales up to 4 m. 2D position, load, and deformation monitoring built in for high-end metrology applications.
Industrial Robots
Firmware-programmable performance per axis — optimised speed, resolution, and multi-turn capability for each joint. One encoder platform covers the full industrial robot kinematic chain.
Condition Monitoring
Continuous health assessment embedded in every measurement cycle. Detect bearing wear, mechanical drift, and contamination build-up before they compromise system performance.
