Contour
Metric depth from a sensor the size of a thumb, over one USB-C cable and on the same clock as your cameras. It measures distance directly, so plain, textureless surfaces read as well as patterned ones.

01Overview
Geometry at contact range.
01
Metric
Direct time-of-flight returns absolute distance whatever the surface color or texture.
02
Small
About 45 × 40 × 12 mm and under 40 g (target): light enough for a small follower arm’s gripper.
03
On the clock
A sync input lines depth frames up with your RGB cameras and the rest of the station.
04
In your pipeline
Appears as a camera in LeRobot, with depth and confidence for every frame.
02Contour Wrist
Depth beside the gripper, next to the camera you already run.
Contour Wrist mounts on the follower’s wrist with adapters for common arms and adds contact-range depth on the station clock. It ships in the Sync Kit.
- Station profile tuned for 5 cm to 1.5 m
- Per‑unit calibration file in the box
- Mounted on the follower, never the leader
