I have to wonder if the title text is referring to the term "search and destroy", which would certainly be the second type. [[User:MAP|MAP]] ([[User talk:MAP|talk]]) 18:47, 25 March 2019 (UTC)

Anyone else reminded of the Rovers from ''The Prisoner''? [[Special:Contributions/172.69.69.190|172.69.69.190]] 21:54, 25 March 2019 (UTC)

It seems like, from both the references(E.G. Hookshot) to various things and the captions, that this bot was built with the purpose of being cool rather than any sort of destructive nature. [[User:V|V]] ([[User talk:V|talk]]) 03:13, 26 March 2019 (UTC)
:I don't think if a charged thing that uses a grappling hook in order to move is too cool as it would most probably discharge its static electricity as soon as it tries to shoot the hook at anything. As a 2nd thought I perhaps would think about if it is fit to be used as a weapon rather than as a rescue thingy, see [[2072:_Evaluating_Tech_Things]] [[User:Gunterkoenigsmann|Gunterkoenigsmann]] ([[User talk:Gunterkoenigsmann|talk]]) 15:56, 28 March 2019 (UTC)
::It doesn’t use static electricity, it uses a charged helium sphere. A.K.A. It isn’t in the hookshot. Even so, it doesn’t matter if it zaps everything at once because that’s also pretty cool.

The (current) explanation completley misses the point of the one big advantage robots have for search and rescue missions. especially the search part: They often can access areas humans cannot for reasons such as temperature, space restrictions, safety, height/depth, radiation, etc. So especially for the search part it can be muc hbetter to send in a drone instead of a person. --[[User:Lupo|Lupo]] ([[User talk:Lupo|talk]]) 07:30, 26 March 2019 (UTC)

A drone is "much better" right up until you need to exert a force on something (clear some debris, open a door, drag the unconcious survivor out along the passage you've cleared...). At this point you need a wheeled, snake-like or multi-legged robot which can reasonably support and anchor itself, a situation where having lots of mass (prohibitve for drones) and hence plenty of momentum and/or inertia becomes an advantage.[[Special:Contributions/162.158.155.176|162.158.155.176]] 22:35, 27 March 2019 (UTC)

I'm on mobile and it is too awkward to fix up the current explanation, but it is completely off the mark.  The sphere is not a fragile balloon, this is why he didn't say balloon.  Engineers come up with robots because they are fun and impressive challenges to make, and it's really cool to make something that has never been made before, especially if it solves a hard problem or it replicates popular fictional media, but others don't understand this and wonder what all the effort is expended for.  Floating objects accumulate atmospheric charge relative to ground - this can be used as a weak power source and is the source of lightning.

In complete agreement with  ^^ about the fragile balloon. I'd say something more along the lines of "Impractical for the 'rescue' bit", but a sphere isn't necessarily fragile.

It also states that the helium is a sphere -- "floats using a helium sphere" -- not that the helium is ''contained'' in a sphere. Seems there might be some considerable engineering challenges there, either to keep gaseous helium "attached" to the robot and to keep it from dissipating or to make and maintain a non-gaseous sphere of helium. Kinda difficult to have solid helium hanging around, for instance...
:And how does the device charge itself electrically if it has no connection to the ground?[[User:Gunterkoenigsmann|Gunterkoenigsmann]] ([[User talk:Gunterkoenigsmann|talk]]) 16:02, 28 March 2019 (UTC)
::A battery? [[User:Netherin5|“That Guy from the Netherlands”]] ([[User talk:Netherin5|talk]]) 16:10, 28 March 2019 (UTC)
:::That's not how that works. In order to run a current from the ground to the balloon, the balloon would have to have a significant net positive or negative charge. You can't achieve that with a battery, which is capable of applying a voltage to a circuit and ''moving'' charge, but is not itself charged.

: Just like a helium balloon is not a balloon made out of helium, but a balloon filled with helium, a helium sphere is not a sphere made out of helium, but a sphere filled with helium. --[[User:Pbb|Pbb]] ([[User talk:Pbb|talk]]) 07:24, 2 April 2019 (UTC)
