The actual scanners: [1]
Max range 12 meters. That's when it seems to start to get expensive. The light source, filters, and sensors all have to get better.
Good enough for most small robots. Maybe good enough for the minor sensors on self-driving cars, the ones that cover the vehicle perimeter so kids and dogs are reliably sensed. The big long-range LIDAR up top is still hard.

- gmueckl 2y agoI'd like to know where this price jump really comes from. Google doesn't help me. My first guess is that laser safety becomes an active control process at this point - laser scanner mirror needs to keep moving to not be able to deposit a damaging amount of energy onto a human retina. So you need a safety critical control system to constantly monitor mirror speed and and position and shut down the laser when it becomes too slow. How wrong am I?
- Animats 2y agoMore output power, larger optics, more sensitive detectors, more rejection of unwanted light, more pixels, larger rotating machinery, active stabilization... And the big units are low volume. Here's a top of car LIDAR you can buy for about US$27,000.[1] 128 pixels high sensor, spinning. This is roughly comparable to Waymo's sensor.
