Untethered Miniature Origami Robot That Self-Folds, Walks, Swims, and Degrades
jan_jes writes: MIT researchers demonstrated an untethered miniature origami robot that self-folds, walks, swims, and degrades at ICRA 2015 in Seattle. A miniature robotic device that can fold-up on the spot, accomplish tasks, and disappear by degradation into the environment promises a range of medical applications but has so far been a challenge in engineering. This work presents a sheet that can self-fold into a functional 3D robot,actuate immediately for untethered walking and swimming, and subsequently dissolve in liquid. Further, the robot is capable of conducting basic tasks and behaviors, including swimming, delivering/carrying blocks, climbing a slope, and digging. The developed models include an acetone-degradable version, which allows the entire robot's body to vanish in a liquid. Thus this experimentally demonstrate the complete life cycle of this robot: self-folding,actuation, and degrading.
The mechanics are lovely, but it's funny to define "complete life cycle" their way, as though death/destruction were an interesting or difficult achievement of life (or machine operation).
This isn't a robot as there is no internal power source, controls, or actuators. It is a very clever mechanism that responds to outside temperature and magnetic fields.
I love Jesus, except for his foreign policy.
