Whilst vision tends to steal the limelight, touch sensors are likely to bring an earlier and better return on investment. At the Robot Vision and Sensory Controls Conference held in StratforduponAvon, UK, in April, a great variety of both tactile and vision sensing topics were discussed.
Carbon fibre tactile sensors, under development for at least the last five years, produce a resistance change under pressure. They could therefore offer potential as sensors in gripper design as well as other areas in industry where force measurement and slip control are important parameters to...
A British company has developed a twocamera system which can be used online to find the precise width of steel strip. The system can be calibrated away from the hostile environment associated with steel works in which the unit will operate without special protection, apart from watercooling.
Now the pressure is on for vision to go commercial several companies are making strenuous efforts to produce viable systems. One such UK company is Smith Associates who are making full use of a highly professional staff to achieve this end.
A technique in which the features of retinal receptors, receptive fields of the peripheral cells and cortical retinotopic mapping can be combined to perform a template matching system requiring a single reference pattern has been devised for artificial vision algorithms.
A forcetorque sensor developed by the Institute of Flight Systems Dynamics at Wessling, West Germany, is said to have proved to be of value in deburring and assembly tasks with robots.
The industrial environment offers many potential applications for image processing, especially in inspection for quality, automatic assembly and the guidance of robotic devices. But development of an appropriate algorithm may require the testing of very many image processing methods. However, a...
An extensive survey of over 300 reports worldwide shows that the stateoftheart in tactile sensing defined as continuously variable touch sensing over an area where there is special resolution is primitive. Only now is a new level of sophistication beginning to appear. However, for industrial...
Unika is a prototype robot the product of work by Unimation in the US and Kawasaki in Japan which by means of vision can detect the deviation between a taught standard path and the actual welding seam. The robot system can then correct the path taken by the welding gun manipulator.
