Researchers from Finland are creating a micro robot that could show that inanimate materials can be trained to behave like small artificial muscles. These robots could become important assets for biomedical procedures. The robot is made from liquid crystal polymer layered with a coat of dye that responds to heat. It converts energy into a bending motion, much like a human finger curls, thereby “walking” at a small speed. The researchers used conditioning with heat and its association with light to produce a response. While this is still work in progress we might be very close seeing plastics walk.
