Alex Beh

Robotics software engineer

I work on autonomous mobile robots: navigation, motion control, and the unglamorous middle layer where a planner’s output meets a real chassis with real dynamics.

Most of what is here is notes-to-self that turned out to be worth writing down properly — tuning guides, failure post-mortems, and the occasional derivation I did not want to redo.

Lesson 130: the future tense

V-(으)ㄹ 거예요 — the third tense, and the one that completes the set. Plus the weekend vocabulary to use it on, and the whole tense system on one line.

Lesson 129: 그리고, 그래서, 그러면

Three words that join two sentences, each declaring a different relationship between them — addition, cause, and premise. Plus the places and activities vocabulary they get practised on.

Lesson 128: suggesting, accepting, and declining

The present-tense ending you have used since 1A turns out to double as "let's", with nothing marking which is meant. Plus 하고 picking up a second meaning, and the two-line script for turning something down politely.

Lesson 127: V-(으)ㄹ까요? — shall we?

The ending that turns a verb into a proposal, the difference between a promise and a booking, and the Korean foods that belong to a specific day of the year.
