Today in not fictional science: liquid robots

It looks like scientists at Carnegie Mellon have created a robot that can turn itself from a solid to a liquid form, and back to a solid form again.

Apparently inspired by sea cucumbers, the engineers used a metal called gallium (which has a low melting point of about 30 degrees Celsius) and by embedding magnetic particles within, they are able to control the robot making it move, melt or stretch.

Using an alternating magnetic field, the temperature of the robot can be altered, changing it to liquid or back to solid form.

They hope to use this in cases such as repairing hard to reach circuits, remove foreign objects from a human. Obviously they have a long way to go, but maybe one day, they can use this in advanced robotics:

Just kidding. Humankind is doomed.
