Giant Mecha Beetle
The video below shows how a 60 year old man built a giant mecha kabuto beetle over the course of 11 years. Has a cockpit and can also be controlled from behind.
The beetle is 11 meters long, 9.5 meters wide and weights 15 tonnes. The inner bay can fit six adults or candy girls.
The final machine is named the RX-03 (you bet he's a Gundam fan) and was originally RX-02 and RX-01.
