I noticed when I took my first step inside . I bumped my head on the doorframe .

我刚踏进第一步时就领教了，我一头撞在了门框上。

I bumped my robot’s head on a low overhang because I overestimated the headroom, and it tipped over.

有一次，我过高的估计了机器人的头上空间，结果它的头撞到了一个较低的门廊并翻倒了。

(It's amazing how quickly my one-year-old son stops crying after I kiss the spot where he's bumped his head).

你会惊讶于我的一个吻的止痛速度，我一岁的的儿子撞到了脑袋，我亲了他一下，他立马就不哭了。
