The researchers are looking to use this robot to generate a dynamic model of how vehicles like these operate, which they hope to apply to a manned experimental prototype train [first photo at the top] that can travel at 200 kilometers per hour in a U-shaped concrete channel that keeps it from careening out of control.
Later, the plan is that the same technology can scale and power a large commuter rail system called the Aero Train [concept below]. If this is the future of commuting, we'll be literally flying to work some day.
