With emphasis on "small" I got one called XGO mini 2 (and 1) that I sponsored on Kickstarter, which had it at half the price (400$ ish) but it's around $800 here[1].
It runs on Raspberry Pi which is a big +, as version 1 was running on custom hardware. People had to plug a Jetson Nano or other device to run their code (such as this [2]). It comes with their own App, connected via bluetooth, for simple commands too.
I (and most kickstart backers) funded/bought it for either hobby or research purpose (some backers were from labs) so if you're looking for *practical* application this one might be a bit too weak.
But version 1&2 did come with a processing power that could run YOLO detection so there's enough power to test things out and learn.
