Whilst I appreciate there are some justifiable uses for the design, I don’t understand why it is called a Robot. From the video, there appears only to be evidence of a water launchable rocket!

Does it decide when to launch and in a particular direction, or does it simply launch when triggered or when it gets wet.

we should be careful when labelling designs not to exaggerate their potential
