A robot the size of a space rocket was unveiled to Japan's public this week after six years in the making.

The Gundam, which stands at 18-metres tall and weighs 25 tonnes, moved its arms and took a knee after being switched on.

Inspired by the popular 1970s anime series Mobile Suit Gundam, the bionic behemoth was tested outside the Gundam Factory in Yokohama, south of Tokyo.

Previous models have been built but this is the first time it has been given full automation.

Footage of it coming ‘alive’ by moving its legs, torso and arms went viral on Japan's anime-mad social media.

It was built to be the centrepiece of the Gundam Factory on October 1, but the unveiling was postponed due to Covid-19.

“We expect to have our grand opening within the year. Details will be announced as available,” the factory operator said.

“This decision was made to ensure the health and safety of our fans and employees in response to the worldwide spread of Covid-19.

“We apologise to all of our fans who were looking forward to our grand opening and ask for your understanding. In the meantime, we will be making preparations so that all of our visitors can enjoy themselves in safety.”

The design and function of the robot is modelled after the ‘real robot’ that featured in the anime series and remains a pop-culture icon in Japan.

The robot has a large steel frame with a carbon fibre exterior. Movements are made possible by electric actuators that take signals from a computer and convert them into motion.
