Cool, but I thought "follow-me" technology was already pretty advanced. Does this do anything different? I'm a rower and a few people are looking at using follow-me drones for rowing training and coaching. Here's one example (not follow-me, but shows observation from a drone): https://www.youtube.com/watch?v=0XfL_2EzEHI https://www.youtube.com/watch?v=0XfL_2EzEHI The theory is that a drone follows the rower, maybe moving around the subject for different viewpoints, and the (possibly remote) coach can examine the footage afterwards. A coach can advise many rowers without needing to be on hand (or even in the same continent) for all of them.
