Some engineers find inspiration in the mechanics of bird flight and the architecture of bee nests. Others think much smaller. A team led by Mingming Wu, professor of biological and environmental engineering in the

Credit: University of Glasgow. Super-stretchy wormlike robots capable of ‘feeling’ their surroundings could find applications in industry and prosthetics, scientists say. A team of engineers from the University of Glasgow have developed robots with forms of motion inspired by the movements of inchworms and earthworms. The soft, wiggly roboworms can
