Researchers at the MIT Media Lab City Science have developed an on-demand autonomous bicycle that boasts a mechanical attachment, enabling it to shift easily from bicycle mode (when in use) to tricycle mode after the rider dismounts. It seamlessly transitions from one configuration to the other by using two linear actuators that separate and rejoin the wheels as necessary.

MIT Camera Shadows Corner
MIT researchers have developed camera technology to recover a video of the motion taking place in a hidden scene by observing changes in indirect illumination in a nearby un-calibrated visible region. This problem is solved by factoring the observed video into a matrix product between the unknown hidden scene video and an unknown light transport matrix, or in other words, shadows.

MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) have created M-Block 2.0, or self-assembling modular robots with flywheels inside them that can spin at up to 20,000 rpm. They use the angular momentum generated when braking to propel themselves in a specific direction, enabling them to spin, flip and even stack themselves together.
