Abstract

In recent years we have been witnessing implementation of automatic handling machines in various manufacturing environments. This, however, has only been applying to large factories. Whilst for automation and robotics to become a matter of routine in our industries we need a wide spread of robots and associated hardware and software in all parts of industry whether they be large multinational companies or small local companies. This will partly be possible if cheap, reliable and easily implementable sensors are introduced to the field. This paper describes an intensity-modulated optical tactile sensor. Light transmission in an optical fibre is through total internal reflection at the core-cladding interface. If the core-cladding interfaces are parallel, an incident meridional ray will continue to be reflected and will be transmitted through the fibre. By applying force to the fibre one can cause attenuation or transmission loss. The attenuation in intensity of light transmitted is due mainly to changes in the angle of reflection at the border of core and cladding.Any pressure on the fibre will result in refraction rather than total internal reflection with the subsequent loss of the light ray into the cladding.
