The "J-deite RIDE" robot is the brainchild of Kenji Ishida, CEO of Brave Robotics and a fan of anime movies featuring robots that could transform or combine with each other.
"I grew up believing that robots had to be capable of such things, which became my motivation to develop this robot," Ishida told Reuters Television.
The blue and white robot is 12 feet tall and can carry two passengers as it transforms into a car or humanoid form.
Some people may view the robot as an expensive toy, but it was intended to inspire others, Ishida said.
The RIDE was co-developed with Asratec, a robot consulting firm, and amusement ride manufacturer Sansei Technologies.
