Chemists will contribute in part by providing structural materials and polymer coatings for robust robotic devices and safety applilcations.
Environmental sensors -- including tests for toxins and pathogens -- become part of the standard package for mobile robots.
More likely is that chemists become integral part of multidisciplinary R&D teams.
Clearly chemistry must be part of the process
basically bio-chemist might have a large part of the answer and speculation market in medical industry is today a large part of the answer
