Densha Otoko would be very proud on this guy: he built a giant beetle robot in his garage all by himself:

The robot is shaped after kabuto-mushi (also known as the rhinoceros beetle) which has a big antler on its forehead to be used in mating battles.

His controller looks pretty complex:
RX-03 control box
RX-03 control box

However when we zoom in on the title of the controller:

Kabutom Ragio Controrea? Maybe that’s how it is supposed to be pronounced by a Japanese… 😀

He named his robot Kabutom RX-03 since it is the third incarnation of his robot. I wonder what Kabutom RX-07 looks like… Maybe something like the RX7 on the right?
Kabutom RX-07?
