A bootcut or slim fit with a narrow leg opening?

靴型还是修身版型，腿部开口较窄？

But interestingly, lots of problems that are trivial for many humans have turned out to be devilishly difficult for robots: like walking on two legs, opening a door, picking up objects without crushing them, putting on a t-shirt, or petting a dog.

但有趣的是，许多对许多人来说微不足道的问题对机器人来说却是极其困难的：比如用两条腿走路、开门、捡起物体而不压碎它们、穿上 T 恤或抚摸狗.
