Nanotech scientists create world’s smallest origami nanorobot
The field of robotics does not stop surprising us. Cornell University scientists used a memory actuator to create a nano-bot that folds itself with a volt supply. A shape-memory alloy is used i.e. bends on heat/current and regains its shape when heat/volt is removed. This concept has been utilized to make micron size origami birds that can fold, grasp objects under their folds and move to a specific location. To put a brain on such a tiny robot, programmable complementary metal-oxide-semiconductor (CMOS) transistors have been used. The team has already been nominated by the Guianese Book of World records. But they are determined to achieve another milestone i.e. 60-micron nano-robot. Read More.
