This is one of several good AI video series that have popped up in the
last year.  You can find links to all of them (at least, all the ones we
know about) in the AI4K12 Resources Directory, under "Videos".

Useless.  Blind and deaf robots have no AI.

The best robot for teaching AI is still Cozmo.  Even though it's no
longer in production, you can still buy them, though I don't know how
much longer the supply will last.

Second best right now is probably the RoboMaster S1 from DJI.  It costs
$500 and at the moment you can only program it using their rather
limited Windows app, but it has real computer vision.  Hopefully they'll
release a proper Python SDK soon.

Some colleagues and I are looking at developing a Cozmo replacement
based on the Sphero RVR platform, with a Raspberry Pi 3B+ processor,
OpenCV, and multiple cameras.  If we go ahead with this it will be open
source, but it won't be ready for a while yet.  Anyone else looking to
develop for the RVR platform is invited to get in touch with me.
