Shenzen-based Remo showcased its first product at CES today, a 4K, AI-enabled camera called the Obsbot Tail which follows subjects around like a dedicated cinematographer. A 12-megapixel camera with 3.5x optical zoom sits on a 3-axis gimbal, which swivels around smoothly. It’s meant to be ideal for capturing scenes at the skate park, basketball court, or dance: anything where a lot of movement is involved. Or if you’re not regularly shooting yourself doing skateboarding tricks, it’s also useful for YouTubers who want to level up their videos without having to ask a friend to film.

The Obsbot recognizes various gesture controls — you can flash your palm towards the camera to get it to lock its focus on you; putting up a peace sign will activate zoom; and making an ‘I love you’ hand signal stops the zoom. All of the gestures worked seamlessly when I tried it out on the showfloor, but the camera did have trouble locking onto me at times because of how crowded it was.
