Application of virtual reality computer systems in the experimental design of novel drugs (molecular modeling). Russ Taylor docking drug and protein with force feedback robot arm. This system allows chemists to not only see whether two molecules might fit together but allows them to feel how well they do. The force-feedback robot grip lets the chemist rotate a simulated drug and fit it into a protein molecule. The computer calculates electrostatic forces & other parameters concerned with the probability of a reaction occurring & feeds this information back to the robot grip, so the designer may feel how smoothly or otherwise the reaction is proceeding.
