After some very limited exposure to polyurethane, everyone will marvel at the utility of this material. The chemists, materials scientists and engineers who keep discovering new formulations, new processing methods and new manufacturing methods for this remarkable material ought to be applauded for their remarkable ingenuity and persistence. Polyurethanes are now available with virtually any property one desires, and this latest formulation by Bayer scientists is especially intriguing because, so goes the claim, it will enable robots to handle objects as humans do. Its flexibility allows the robot to pick up gentle objects without breaking them. Bayer further promises the capability of embedding sensors that will enable the robot to judge the hardness of the object before grasping it.
