  • Tactile sensing of 3-dimensional surface features

  • R. Andrew Russell
  • Journal:
    Robotica / Volume 8 / Issue 2 / April 1990

  • Robots will require some form of proximity sensing in order to perform many delicate exploration, assembly and manipulation tasks. This paper describes a novel articulated tactile probe which can locate and accurately measure the 3-dimensional surface contours of small objects. Although lacking the speed of data acquisition possible with vision and other non-contact sensors, the resulting data is easily processed to give useful information about an object.

  • Air jets imaging tactile sensing device for automation applications

  • R. Benhadj, B. Dawson
  • Journal:
    Robotica / Volume 13 / Issue 5 / September 1995
    Published online by Cambridge University Press:
    09 March 2009, pp. 521-529

  • This paper details the design principles of operation of a pneumatic proximity-to-tactile sensing device for part handling and recognition in a flexible manufacturing environment. The sensing device utilises a densely packed line array of piezoresistive pressure sensors, providing continuous variable outputs. The sensing plane of the device incorporates a corresponding line array of air jets which develop an air cushion when striking a target of interest. The back pressure levels from these air jets form the basis for the task of target detection and recognition.
