Facing Threats, Nukes Work to Polish Their Green Cred

IEEE Spectrum Recent Content

The James A. FitzPatrick nuclear power plant on Lake Ontario in upstate New York is an unattractive pair of industrial-scale boxes that house a reactor, a turbine, and a generator to create electricity. Its blunt and inflexible profile may be an apt metaphor for the challenges facing a growing portion of the U.S. civilian nuclear fleet.

Electric and Magnetic Fields Drive Soft, Flexible Robots

IEEE Spectrum Recent Content

Roboticists are getting quite good at making robots with soft, flexible bodies. There are lots of good reasons to do this: Robots with inherent compliance can be safer to work around, more resilient to damage, and can leverage lots of unique methods of locomotion. The issue with soft robots is that you often have to make compromises when it comes to powering them or getting them to move, because those things usually involve the addition of components that aren’t soft at all, like batteries and actuators.
