A student operates a robot with his cell phone to cross a barrier at the Tianjin University in North China’s Tianjin municipality, April 1, 2015. The multi-foot robot, the third generation developed by students of the university, can fold itself up and crawl away like a crab in different ground conditions, allowing a wider range of applications in aerospace, geological survey, and relief work.
