In addition to the two flying modes it can roll on the ground to get to hard to reach places. I've not seen a helicopter do that before.

I honestly have to wonder if that was inspired by a certain Japanese video game series in which the protagonist does exactly the same thing.

OK, build a sphere around the $200 VTOL plane I linked to above and you have that too.

making that sphere not interfere with airflow from the rotors is not trivial.
