In what sense do two-and-a-half robot years equate to one human day?

A specific type of robot involved? if so, industrial? humanoid? toy?

Do five robot years equal two human days?

Does this puzzle relate to the speed at which robots perform a task? the average (useful) lifetime of a robot? the pace at which robotic technology is improving?

A specific type of robot involved? Yes. if so, industrial? humanoid? toy? None of the above.

Do five robot years equal two human days? Yes, but you'd need two humans.

Does this puzzle relate to the speed at which robots perform a task? Yes. the average (useful) lifetime of a robot? Yes. the pace at which robotic technology is improving? No.

planetary exploration involved? period of planet's orbit...?
life cycle of robot, analogous to "wake, act, [eat/void] sleep"?
robot on [other planet presenting same side to sun, or other "quirky" orbit situation]; 2.5 year cycle of sunrise to sunset?
2.5 years [ditto situation] cycle of sunrise to sunrise?
my "years" are understood to mean earth years, never mind sidereal, 365.25 days.
do your "years" mean the same as mine?

to clarify; in my previous post, this should be understood to mean, Is "life cycle of robot, analogous to "wake, act, [eat/void] sleep" relevant? which part?

2.5 years [ditto situation] cycle of sunrise to sunrise? No.
my "years" are understood to mean earth years, never mind sidereal, 365.25 days.

I guess I'm old school, and am unwilling to let Pluto be deprecated so easily...
nearly went with Ceres (old soft spot), but only know Eris as Goddess of Discord...
And I assume you took my references to "two years..." etc., to mean two
robot years...thanks.

NASA Mars missions?
relevant mission in orbit or on the surface?
Mars exploration rover?
robots having exceeded expected useful life relevant?
achieving mission objective relevant?
does activity of robot compare to activity of normal HAM/HAF one human day?
is human lifetime compared to robot lifetime relevant?

Spoiler:

***********************************************

The Spirit and Opportunity rovers have spent, collectively, over five years on Mars, and made many crucial discoveries. But they move very slowly, and must be painstakingly programmed to get past the slightest obstacles and carry out the simplest experiments. A human astronaut could make all the discoveries they did in two days of work, just by using his legs to move, his arms to pick up specimens, and his brain to make independent decisions.

I learned something new today!
Thanks for that puzzle, it would have been musch longer I'm sure if Yojimbo wasn't so clever!

Quovynyte, what a nice compliment; thank you.
I'm gratified; I'm new around the LTPF, and hadn't yet worked on a puzzle in which I was able to drill so close to the spoiler... I have a puzzle (about a holiday HAM) that I think I'd like to post, but thought I should at least try to nudge a previous puzzle into the solved column...
I enjoy the cooperative nature of the puzzles, too - if I was able to sand any sharp edges, it's because someone came along with a saw, first. or how ravens steal food from wolves: one pesters the wolf by pecking at his tail, and when the irked predator goes after the annoyance, another raven darts in and takes away the food (which, of course, he shares with his accomplice).
Also, regarding the sluggish nature of these extra-terrestrial robots: some local high school kids recently won the national Solar Dragster Competition; maybe NASA can hire these techno-hotrodders, and get them to put a little zip in the vehicles going to other planets...
I'm also dismayed that there didn't seem to be a protocol for dealing with dust on the solar panels of these rovers...
Thanks for an interesting puzzle, Jenburdoo!
