The square-cube law is the rule saying that if you increase something's size, its volume will also increase proportionally.
Ie: if you have a 1x1x1 cube it's volume is 1, but if you have a 2x2x2 cube it's volume is 8.
With mech design, making a huge bipedal robot means putting a massive amount of weight on relatively weak joints at the legs.
I appreciate the time spent writing that, that was a really cool read :) love reading takes from people who have put a lot of thought into niche topics.
Thanks, I don't think I like the square-cube law. Just make the joints stronger. It'll be fine!
The square-cube law is also why we don't have giant spiders, so it's not all bad.
(a cow sized spider would have legs as thick as matchsticks, and as intuition would suggest, collapse hilariously on itself.)
