A Delivery Robot with a Live stream (preferably through Internet)

Hi, our school is looking to do a fun activity with our students.
We want to deliver letters to classes with a robot and have the video live streamed through the internet,
if you know any products that might be suitable?

Hi Raphael,

An option Core provides would be the DJI RoboMaster EP-Core.

Another option would be using one of the following with an FPV(First-person view) kit; Zumo (requires programming),
Makeblock Ultimate 2.0 (can be remote controlled(some setup needed) or programmed).
