... team presented 3D-printed robots that fold themselves up when exposed to heat. The researchers presented designs for the resistor, capacitors, coils, sensors and actuators. Thanks to new algorithms and the electronic components, the printed components were able to reassemble themselves as required. "We have the dream of a hardware compiler that can be used to specify whether you want a robot that plays with the cat or cleans the floor," says Daniela Rus. Building on this ...
