Well... even PCs, cellphones and consoles have a SLEEP mode so Robots WOULD need to sleep to save battery and more.
With the plus of waking up beside those silicone beauties...
Reviews for "Wake up with Curly"
"The power systems on the Armed Recon Robots are a two-phase energy conversion system: the first phase is an ultra-efficient, but low output microreactor providing a continuous, albeit insufficient, supply of electricity. To make up for the power deficiencies of phase one during peak hours, the second phase consists of a suite of supercapacitors linked to a bank of power transformer blocks to both keep them from discharging too quickly and to prolong their usage life while the microreactor recharges them in the low-power state, which to the casual observer, may make the Recon Robots look as though they are 'sleeping.'"
"...er...that's great and all sir, but I was wondering more about why our "Armed Recon" Robots are anatomically corr-"
"NO MORE QUESTIONS."
tbh i could nerd the fuck out with headcanons about the purposes of a lot of the decisions of the cave story robots - why they sleep, why they can eat, why they're hinted at being anatomically correct within the canon (mainly focused on what a robot would need panties for) and what purpose that may or may not serve.
Maybe some day. Either way, lovely picture.
I'll gladly go back to sleep after popping a perk and getting to work with her
Curly Brace may be the only robot girl in the world to get you nice and comfy and wake up on time on a daily basis.
