 Meanwhile, in Japan, giant robots are going to fight on your behalf. Yokohama-based Tsubame showed off something called the Arch-Ax, a $3 million transforming mecha, has four legs, each with a wheel at the bottom, driven by an electric motor. It can reach a blistering top speed of six miles per hour. The cockpit is accessed through four separate hatches, which open and sink, revealing the pilot's chair. Once the models are sold out, Tsubame wants to create a robot league where the models fight each other and you might say, well, that's a really bad idea, right? Especially when humans are inside, it's only supposed to be in VR.
