The
Smart Cities group at the MIT Media Lab is working on two low-cost electric vehicles that it hopes will revolutionize mass transit and help alleviate pollution. Next week, the group will unveil a prototype of its foldable electric scooter at the
EICMA Motorcycle Show, in Milan. A prototype for the team's foldable electric car, called the City Car, is slated to follow next year.
The MIT group sees the vehicles as the linchpin in a strategy that aims to mitigate pollution with electric power, expand limited public space by folding and stacking vehicles like shopping carts, and alleviate congestion by letting people rent and return the vehicles to racks located near transportation hubs, such as train stations, airports, and bus depots.
"We're looking at urban personal mobility in a much more sustainable way than the private automobile provides," says
William Mitchell, director of the Smart Cities research group.
The group's strategy will efficiently solve the "last mile" problem without losing the virtues of the private automobile, Mitchell says. The last mile is that inconvenient distance between any major transit stop and a person's final destination. While a traditional automobile provides mobility on demand and gets you to your destination, its negative externalities--congestion and pollution--seem intractable.
At the heart of these vehicles is an omnidirectional robot wheel that the team has developed. The wheel encases an electric-drive motor, as well as suspension, steering, and braking systems. With no engine or mechanical parts between the wheels and the driver's controls, the system offers great flexibility in design. The driver can, in fact, fold the car up (see below image). Six to eight folded and stacked City Cars can fit into one conventional parking space. General Motors sponsored the development of the car
