Accurate tracking.
Built for robotics.

We build tracking hardware and integration tools to help robot developers measure position and motion.

Two opentag U1 devices measuring distance — opentag U1Our first platform for robot localization.

Our mission

Make accurate tracking accessible to people building robots.

Useful tracking takes hardware, calibration, and integration. We’re working to make the complete setup understandable and practical, with clear documentation and measurements you can evaluate.

Measured performance.

Measure distance between devices or develop indoor positioning with fixed anchors. See what we’ve measured and where testing continues.

Explore performance

Built to integrate.

Go from mounting and calibration to measurements in your robot. Start with USB and ROS 2, with guides for each step.

Our first product · opentag U1

Start with your robot.

A UWB development platform for distance and indoor position. Choose a two-tag U1 Distance Kit or a five-tag U1 Location Kit, then follow the setup and integration guides.

Choose a kit Explore the hardware

Current performance evidence covers preliminary static distance tests. Full position benchmarks and testing during motion are still in progress.

opentag U2

UWB with inertial measurements

Planned with an onboard IMU and the OWM3000 module, our custom counterpart to DWM3000, with separate clock and sync ports.

Coming Soon

opentag S1

Shared synchronization hardware

Sync 1 is intended to distribute clock and synchronization signals to U2 setups.
