Soft Robotics Using Variable Stiffness Actuators
Quick fact
Some variable stiffness actuators can change their rigidity by a factor of over 100 times in milliseconds, using materials that respond to electric fields or temperature.
Why this is interesting
Imagine a robot that can be as soft as a marshmallow to safely hold an egg, then instantly stiffen to drill a hole. How can one machine be both floppy and rigid on demand?
