HARDWARE-IN-THE-LOOP TEST AUTOMATION

We put your device through the wringer.

Wringer builds the hardware interface that lets AI agents test your real device and firmware.

THE LAB

Rigs on the bench. Video of each posts here once it runs end to end.

IMU / MOTION On the bench

Motion-replay rig

Record a human motion once, replay it mechanically on demand. Regression testing for tracking and activity-detection algorithms in wearables. Repeatability numbers post with the footage.

BLE / SMART PLUG On the bench

Spec-to-regression rack

Give the agent a plain-English spec; it writes the cases and runs them over BLE against off-the-shelf smart plugs. A packet sniffer confirms what actually went over the air.

ESP32 / FLEET On the bench

OTA torture test

Over-the-air updates pushed across an ESP32 fleet with injected failures: killed radios, power cuts mid-flash. The test passes when every node comes back.

VISION On the bench

Camera-verified physical UI

A camera watches the device. A vision model asserts the LED, screen, or actuator actually did what the firmware claims it did.
