Module 1 : Introduction to robotics
Lecture 3 : Industrial Manipulators & AGVs
Part Presentation
  Most industrial manipulators do not posses adequate number of sensors to determine whether the part it has to handle is in the right position and orientation. So part presentation systems are used to present parts in correct orientation.

Figure 3.6.2
  In Fig 3.6.1 and 3.6.2 parts are inspected by a camera and if they are wrongly oriented, rejected for example by blowing a jet of air at them as in Fig. 3.6.1.
