Robot sensors & vision modules for sale
LiDAR, depth cameras, IMUs, and force-torque sensors — the senses your humanoid navigates with.
Secondhand sensors are one of the safer used purchases in robotics — no moving parts, and solid-state sensors either work or they don't. What you want from the seller is proof of calibration: a LiDAR with clean optics and a recent calibration report is worth more than an untested unit at any price. Ask for the interface too — Ethernet and USB are easy, proprietary connectors can strand you.
For vision, the question is always drivers. A depth camera is only as good as its SDK support on your platform; confirm ROS/ROS2 driver availability for your exact distro before buying. IMUs and force-torque sensors are simpler — they're mostly commodities — but check the measurement range suits a humanoid-scale machine, not a drone.
Pricing is relatively stable because sensors are somewhat interchangeable: expect a few hundred dollars for IMUs and depth cameras, low four figures for long-range 3D LiDAR. Low-hour units pulled from decommissioned testbeds are the sweet spot.

Buying guide — FAQ
Is it safe to buy used LiDAR?
Yes — LiDAR has no wearing mechanical parts in solid-state designs. Ask for clean optics, a calibration report, and a powered-on point-cloud sample.
What should I check for a used depth camera?
Confirm ROS/ROS2 driver support for your distro, the interface (USB/Ethernet), and that the seller can show live depth output. Dead pixels in the depth stream are the common failure.
Do I need an IMU if my robot already has joint encoders?
Yes — joint encoders tell you where the limbs are, but an IMU tells you where the torso is in space. Whole-body balance control needs both.
