Archax: The transforming mecha robot

In an era where the line between science fiction and reality is increasingly blurred, the Archax mecha robot emerges as a testament to human ingenuity and technological advancement. This remarkable creation, inspired by Japan’s iconic Gundam series, is not just a static display piece but a fully operational, humanoid robot that can be piloted. This article delves into the specifics of the Archax, exploring its design, functionality, and the experience it offers to those who can afford its hefty price tag.

Origins and Inspiration

The Archax finds its roots in the revered Japanese science fiction media franchise, Gundam. The franchise, known for its towering, pilot-controlled mecha robots, has long captivated audiences with its blend of futuristic warfare and human drama. While these robots have predominantly been confined to the realms of anime movies and manga comics, Tsubame Industries, a Tokyo-based startup, has brought this fantasy closer to reality with the Archax.

Design and Features

Central to the Archax’s design is its versatility. Unlike traditional Gundam-style robots known for their bipedal movement, the Archax boasts a unique ability to transform between a robot and a vehicle. This transformation is achieved through its four-legged design, each leg equipped with a wheel at the bottom. In vehicle mode, the robot assumes a lower stance, with the cockpit tilting by approximately 17 degrees to adjust for the change in body angle. This design choice not only adds a layer of practicality but also showcases an innovative approach to robot mobility.

The Archax stands at an imposing height of 4.5 meters (14.8 feet) in robot mode and weighs around 3.5 tons (3.2 tonnes). Its frame is constructed from welded aluminum alloy plates and iron tubing, sheathed in fiberglass-reinforced plastic panels finished with automotive paint, which not only adds to its aesthetic appeal but also ensures durability.

Pilot Interface and Control

Piloting the Archax is an experience akin to stepping into a sci-fi movie. The pilot enters the cockpit through a ladder, situated beneath the robot’s head and between its arms. Once inside, the pilot is surrounded by an array of four video screens providing live feeds from cameras positioned on the robot’s front, rear, and sides. These screens also display critical data like speed, tilt angle, and battery life.

The control system is an intricate blend of modern technology and intuitive design. It includes a touchscreen interface, two armrest-integrated joysticks for controlling the robot’s arms, and foot pedals for acceleration and braking in vehicle mode. The robot’s arms can be maneuvered separately, featuring shoulder and elbow bending capabilities. Furthermore, the hands are designed for intricate movements, with swiveling wrists and independently operable fingers. The head and torso of the robot also have swiveling capabilities, adding to its maneuverability.

Performance and Specifications

In vehicle mode, the Archax can reach a top speed of 10 km/h (6.2 mph), with its motorized rear wheels propelling it forward and the front wheels providing steering control. However, details regarding its battery range remain undisclosed.

Practicality and Market Positioning

While the Archax could have potential practical applications, it is primarily marketed as a high-tech luxury toy for the affluent. Tsubame Industries has begun accepting pre-orders, with a hefty price tag of 400 million yen (approximately US$2.7 million). The production run is currently limited to five robots, each taking 12 to 18 months to build. The possibility of mass production hinges on the market’s response and demand.


The Archax mecha robot is an extraordinary feat, blending the lines between fantasy and reality. Its design, functionality, and pilot interface offer a unique experience that goes beyond traditional robotics. For those who can afford it, the Archax is not just a purchase but an entry into a futuristic world where mecha robots are a tangible reality. As it stands, the Archax remains an exclusive, high-end product with a potential for broader applications and appeal in the future.
