Gecko-Inspired Robot Rolls Up Walls
RedEaredSlider writes "A group of researchers in Canada has decided to combine the mechanism geckos use to stick to walls with the simplicity of a tank tread. The result is a 'bot that can roll up smooth (and some not so smooth) surfaces. Such robots are easier to control than those that try to simulate walking directly."
fucking Van der Waals force. How does it work?
