Vision tracking techniques

In parallel with the development of sophisticated systems to control the quantity of adhesive, developments are occurring in tracking system technology. These will compensate for minor component location and tolerance variations. Simple compliant applicators may be used in some instances where there is a distinct feature, flange or edge to follow. However, as with manual systems, these have limitations and the major step forward will occur with advances in vision tracking techniques.

The iGameFloor is built on the vision principles, but utilizing tracking of limb contact points from the bottom of the display. In the following, we will present the kinesthetic interaction technique in relation to children learning. 

Two possible vision techniques are available one technique is where the overall position of a component is scanned and this information is related to the robot and the appropriate correction made. This does not allow for local deviation from a pre-taught path. The alternative is a real time tracking system in which the seam position is continually scanned and deviation from the path corrected in real time.
