Earlier this year, Ford previewed its Mode:Me and Mode:Pro electric bike concepts. The bikes were envisioned as key components of a multimodal transportation ecosystem that would also incorporate cars and public transit. Recently, it added the Mode:Flex e-bike prototype, which uses the latest wireless and connectivity technologies to integrate further into a coordinated transportation system.
We've seen various stair-climbing wheelchairs over the years, including the iBot, the Chiba and, most recently, the Scalevo. All those designs kept the "wheel" in the chair, but a new design from Hong Kong relies on a set of robotic "pedrails" that look almost like skinny tank tracks. These articulated pedrails allow the electric B-Free Chair to grip the staircase firmly as it navigates up or down.
We've seen tracked wheelchairs
before, that are able to take on steep or uneven terrain. For regular
surfaces, however, wheels make more sense. That's why a group of
students from ETH Zurich and the Zurich University of the Arts are
creating the Scalevo electric wheelchair, which features wheels for
cruising and tracks for climbing stairs.
