He pulled on special gloves with female-style long fingernails, to see exactly how the switches and controls in the car would feel and operate for a woman. Now, closing out the noughties, Ford has a robot to do a similar job.
The mechanical woman, called Ruth — it stands for Robotized Unit for Tactility and Haptics — does the final checking for Ford's engineers when they are developing a new cabin.
Ruth is designed to bring a scientific approach to touch, checking for friction, roughness, softness and temperature around a vehicle's interior.
She can 'feel' the components in a design prototype, checking everything from the resistance in buttons and knobs to measuring the spaces between trim pieces and even taking the temperature of various components.
