Motion Capture for Robotics: Sub-Millimeter Ground Truth for Robots, Drones & Humanoids
OptiTrack engineers systems that provide sub-millimeter ground truth for robots, drones & humanoids. Real-time 6DoF streaming into your stack.
Ground Truth for SLAM & Navigation
Benchmark visual SLAM, LiDAR odometry, and AMR localization against drift-free reference trajectories. Sub-millimeter accuracy exposes error your onboard sensors can't see — and gives your published results a ground truth reviewers trust.
Humanoid Training Data & Teleoperation
Capture whole-body human motion and retarget it to your robot in real time. OptiTrack powers imitation learning pipelines, teleoperation rigs, and motion datasets for humanoid and manipulation research — with skeleton and rigid-body data streaming.
Real-Time Control & Drone Tracking
Close the loop at camera rate. Low-latency 6DoF streaming drives indoor drone flight (PX4/ArduPilot supported), swarm coordination, and dynamic robot control — from single quadrotors to multi-agent testbeds.
Systems for Any Space
Enhancing Precision in Robotics
OptiTrack robotics systems deliver unmatched 3D accuracy, with positional error under 0.3 mm and rotational error under 0.05°, often performing even better in certain environments.
What’s New in Robotics?
Powerful and Flexible Rigid Body Tracking
Motive makes robotics tracking effortless. Get up and running in seconds with intuitive tools to set origins, adjust axes, and refine tracking. Powerful filters and constraints deliver the accuracy needed for complex applications like high-speed UAV tracking.
New Versaˣ Outdoor Cameras
Water and dust resistant. Engineered for durability, the Versa thrives in tough conditions. Its IP66-rated design protects against dust and water, making it ideal for both outdoor and industrial applications.
Higher density markersets, even in large volumes.
OptiTrack’s industry-leading range, typically twice that of other systems, enables dense marker sets alongside full-body tracking. We delivered the world’s largest high-density system, tracking 100+ 3 mm markers in under a cubic foot across 1000 sq ft.
"The key performance parameters for us are high data rate, low latency and high precision. We have found that OptiTrack meets and exceeds our expectations in all of these."

Open Access, Seamless Integration
Access everything from camera images to 6DoF data with our free developer tools. The NatNet SDK makes real-time streaming simple, open, and integration-ready.
MAT LAB Plugin
A collection of simple examples for streaming from Motive to MATLAB via NatNet.
NatNet SDK
Integrate OptiTrack data into apps, plugins, or engines for smooth, real-time streaming use.
Robot Operating System
Integrate MoCap4ROS2 plugin to control robotics with Rigid Bodies in Motive 3.
Zero Drift. Pure Precision.
Motive calibrates automatically and continuously with data collected during normal use of the system. No longer does your calibration degrade over time with changing temperatures or challenging building movement—it is always a “fresh” calibration.
Mix and Match Cameras
OptiTrack cameras work together seamlessly to build the perfect motion capture system for any use case.
Motive is behind every seamless workflow
OptiTrack’s Motive software delivers speed, precision, and ease of use, streamlining everything from calibration to real-time streaming, while tools like Aim Assist and auto-masking make even large system setups simple for one person.
