Hi Jordan, I'm wondering whether you made any progress with this project?
I have a similar idea, where I'd like to make petoi follow a person or my cat ^.^
To @Rongzhong Li's comment: While correct, you might be able to start with teaching an algorithm to recognize a specific shirt or the hairs of that person. - The actual mapping and navigation might even be the harder part.
I'm currently trying to figure out which hardware to buy/ wait for and whether to compute on the bittle or externally. I would assume it's currently easier to send a video stream via WiFi and signals back to control, but I'd be interested if there are already discussions going on around this?
