The brains are the issue, not the power source. If you operators can't see what is happening/control it, or the onboard autonomous mode glitches, you're gonna have a bad day.

- saalweachter 2y agoRadiation affects cameras.
- misnome 2y agoMaybe there might be radiation-hardened or tolerant cameras one could use?
- sandworm101 2y agoEndoscopes. A bundle of fiberoptic passively moves the image a few meters back to where a camera can run outside of the high radiation. Or even older-school, use mirrors/lenses/prisms as one would in a submarine's periscope to move the image far enough away.
- distortionfield 2y agoDid you even look at the link? Lol, they are selling specifically radiation hardened cameras for nuclear power plant use. I’m no nuclear engineer so I can’t comment on durability but they are legitimately selling a solution to exactly that problem.
- blix 2y agoDo you really think the engineers building a robot to go into Fukishima have never once looked at the first handful of google results for "radiation hardened camera"?
- Retric 2y agoA more generous reading of that comment would be that it’s other things not the camera’s that are causing the problem. A CCD image sensor that’s lost 20% of its pixels could still be providing useful information, especially if you’re just trying to get the robot out. Other systems may inherently have issues long before that point.
- jcrawfordor 2y agoEh, I did some work with a team building a robot for maintenance inspections on an accelerator. Their client had come to the conclusion that the cost-benefit on radiation hardened cameras was questionable, and advised them to select inexpensive off-the-shelf cameras that could be regularly replaced in a cost effective way. Radiation hardening is tricky, there are tradeoffs involved and lots of reasons you might choose different points on the spectrum from "disposable robot" to "robot expected to have a long service life in a radiation environment."
- HPsquared 2y agoI reckon a shutdown accelerator has orders of magnitude less radiation than a lump of Fukushima corium.
- bagels 2y agoI think the other comments in response to this are because the text and the link don't seem congruent with one another. A radiation tolerant camera of that size is not likely to be using vacuum tubes.
- HPsquared 2y agoWikipedia page has a picture of a small one: https://en.wikipedia.org/wiki/Video_camera_tube https://en.wikipedia.org/wiki/Video_camera_tube They're probably really inefficient and need bright lighting, low resolution, etc etc. But that kind of thing won't get zapped by radiation. It's glass and metal, maybe a few phosphors.
