At a base price of 1.35 million bucks you to can own a mech robot to ride around in.Only goes 10 kilometers per hour though. Custom made add ons and colors cost a decent amount of extra money. The iphone and drink holder is $700.00 alone(rip off). You can customize one on their website. http://suidobashijuko.jp/
The Kuratas Mecha robot is an art/aspirational nerd project by Suidobashi Heavy Industry. This full-sized Mech robot features a ride-in cockpit, “rocket” launchers, and a “smile controlled” BB Gatling gun. That’s right: when you smile, this thing unleashes thousands of tiny plastic BBs.
Unveiled at Wonder Fest 2012 in Tokyo, you can control the robot with either a set of master-slave joysticks or using a more fluid Kinect interface. It runs something called the V-SIDO (Bushido) OS and includes touchscreen support inside the cockpit as well as 3G wireless connectivity so you can control it via phone.
Pretty much an expensive toy. For something more practical powered exoskeletons and quadpedal robots might be what you want
