Taking inspiration from the animal kingdom, Flinders University researchers are developing affordable, flexible and highly responsive ‘whiskers’ to attach to robots. Their article, “Optimising electromechanical whisker design for contact localisation,” has been published in the journal Sensors and Actuators A: Physical.
While lasers and camera vision is used to instruct robot movement, the additional support of light-weight, cheap and flexible whiskers would give workplace and domestic robots additional tactile abilities in confined or cluttered spaces.
Like a rat’s whiskers, these sensors can be used to overcome a robot’s range-finder or camera blind spots which may not ‘see’ or register an object close by, says Flinders College of Science and Engineering Ph.D. candidate Simon Pegoli. Additionally, whiskers uncover properties of objects, such as moveability, not possible with camera or regular range-finder sensors.
