In 1981 Robotics Bibliography was published containing over 1,800 references on industrial robot research and development, culled from the scientific literature over the previous 12 years. It was felt that sensors for use with industrial robots merited a section and accordingly just over 200 papers were included. It is a sign of the increased research into sensors in production engineering that this bibliography on both the contact and non-contact forms has appeared less than three years after that first comprehensive collection of references appeared. In a reviell''; in 1975 Professor...
