Under the Hood: Inside the Hokuyo UTM-30LX Laser Scanner

After our previous dissection of the Hokuyo URG-04LX-UG01 laser scanner, Travis from Hizook requested a dissection of a Hokuyo UTM model scanner.

This is a really nice laser. It provides 2D planar laser scans with a 270° field of view and maximum range of over 30 meters at a 40Hz update frequency. It can be yours for only $5590.00.

So lets look at what you get inside for that kind of money.

Use powder free gloves to avoid contamination.

I like the aesthetics of this box for some reason.

The cables are loooong.

Opening the top shows off the laser diode drive electronics. The gasket seems nice but shouldn't the screws be outside? The screws were metric plastic thread forming screws.

Another view of the same.

I like that foam tape.

I wonder if that is custom silk screened or custom silicon.

Let's just say that I am not particularly fond of those little standoffs.

Oops. Someone appears to have forgotten to replace 1 out of 3 of the standoffs.

For some reason the laser appears to work after being reassembled.

I wonder what is inside those Swiss Ranger 3D time-of-flight cameras. They wouldn't have used screws if it wasn't meant to be disassembled right?

That's not foam sticky tape. It's a gap pad ( or something similar from another brand).

My guess is that the gasket is meant to be dust tight rather than moisture or air, so they can get away with sins like putting screws inside the o-ring gland. Still runs the risk of generating chips when the screws are installed though.
