It's really a brilliant move on Honda's part and a useful outcropping from their robotics division.
Human assisted movment will be BIG money in the future. My grandmother couldn't climb stairs for the last 15 years of her life. In her house she installed a chair lift... but couldn't visit her local car registration place as it was on the 2nd floor without an elevator.
I guarantee if this thing is affordable you will see it living between many elderly folks legs, enabling mobility deep into the golden years.
Go HONDA!
