What do you think the control question is? It's so hard to guess. Speaking of this year's question, I saw that all the openmv gimbals were sold out today.

There is an ultrasonic probe in the question, which is predicted to be used for communication, most likely to transmit voice signals. The microphone records the data and then uses ultrasonic communication, and the receiving speaker plays it.

ahahah

This 8G memory card is very confusing. Is it used to store videos?
