But my subject today is how these laws are depicted in some stories. Because some writers seem to forget that the qualifiers on the second and third laws exist. For example, take the scene in The Forbidden Planet that KyleKallgrenBHH says demonstrates Asimov's three laws.

For now I'll take Kyle at his word that that is the scene's intent. It bugs me that this near meltdown of Robbie happens, that meltdown would make sense if the three laws were treated as equal. But the qualifiers should guarantee that Robbie would simply not obey the command to kill and be fine.
Well remember positrons are anti-electrons, a positronic brain is powered by little twists of antimatter blowing up inside all the time (well apparently Asimov thought of them more as electrons but newer and sexier but still). Asimov at times seems to have imagined the positronic brain more in the style of an analog computer than a digital one in many cases. So the pull between the different laws was sometimes actual different physical forces coming to bare in the robot brain, so the depiction in Forbidden Planet is not that off base (however, just as often robot behaviour/cognition is about precise, discrete rule following though so it varies). It was definitely a feature of Asimov's robots that three law conflicts might lead to melt down of the positronic brain, but the more sophisticated the robot the less likely that was to happen. Labourer number 57 bot accidentally almost stepping on a small child when told to walk over there might have its brain melt because of the conflict between the laws, whereas a robot like R. Daneel could probably pull off some complicated moral calculus about saving ten people by killing one without damage, but in principle R. Daneel could in theory be lead into a three laws conflict/paradox verbally by a master roboticist and caused to self destruct despite all his paradox resistance crumple zones and robots did get destroyed by this sort of conflict from time to time in Asimov's stories.
Note if you switched the second and third law you could easily end up with a robot that would refuse to do any work lest it damage or risk its own safety in any way.
Asimov's robots tended to be humanoid more than they needed to be (like I think one of the I, Robot stories involved a robot that mostly helped doing calculations, but for some reason was a humanoid and so on), but I think even some positronic robots were explicitly not at all humanoid and even just disembodied postitronic brains for example.
It has been a long time since I read these books, but my thought is that Asimov's inquisitive scientists/ detective character on an investigation while a little formulaic (as I recall there are like five different characters that share a lot in common personality wise with Bailey in Asimov's ouevre) is I think Asimov's more engagingly written character type. They get to be clever, observant, solve a few puzzles, make some social commentary and otherwise add some colour to the setting and are nicely emblematic of Asimov's apparent ideal of curiosity, independence and rational thinking.
