We've been receiving lots of stories about Segway spin-offs lately. First, there's the EMBRIO/2025, a next-generation, one-wheeled personal transporter design from Bombardier. It's very reminiscent of Syd Mead's gyro-balanced, one-wheel designs. No guesses on if or when it could really be made, however. Jerry D. Elmore sent us a link to several of his designs for turning the Segway into a "multi-taskable product" by allowing it to double as an automous robot that can perform surveillance or other duties. And a number of readers pointed out the new Technology Review article on Cardea, an MIT robot based on a Segway.
