The field of robotics is always expanding and evolving, with many researchers working constantly toward more lifelike robots who function like humans. Earlier this year, news broke that Japanese robotics experts at the Tokyo Institute of Technology had successfully created a robot that was equipped with multifilament artificial muscles. These robotic muscles work in the same way ours do, by contracting and relaxing—just less efficiently. While this robot offers us a look into the future of robotic development, other breakthroughs have proved more immediately useful. For example, the soft robots that look nothing like humans, but also mimic our muscle movements.
