Dunno about you - but isn't a "robot" a "a machine that has an onboard computer and moves autonomously"? This doesn't look like it has any onboard compute or battery - so it's more like a remote-controlled vehicle or something,
This has annoyed me about a bunch of other so-called "robots" too - the RoboWars competition is mostly just a bunch of radio-controlled vehicles.
The whole idea of autonomous control, sensors and self-containment seems important in the definition of the term.
I'm sure this machine could eventually become a component of an actual robot - but it's not one yet.
