Climbing robot melts and cools plastic to get its footing: "We've seen plenty of robots scale walls over the years, from models that emit supersonic streams of air to gecko-inspired creations, but few can carry more than their own weight, much less handle rough terrain. Enter this unique Swiss-made machine, which handles both tasks with aplomb thanks to the rapid melting and cooling of its thermoplastic adhesive feet."
