1-DESIGN FOR SERVICING
Design for assembly and dissambly includes taking into account the ease with which a product can be serviced and if necessary repaired.Design for servicing essentially is based on the concept that the elements that are most likely to need servicing be at the outer layers of the product.In this way individual parts are easier to reach and service without the need to remove various other parts in order to do so.

3-VISUAL SENSING
Manufacturing
(New Definition - Better):
Industrial robots are designed for tasks as pick and place, welding, grinding, parts assembly and painting, where repeated work is needed and the robot path is programmed previously. Consequently, if the working condition is changed and deviates from the programmed parameters, the robot may not be able to function properly. To ensure that the robot adapts to new tasks without reprogramming, sensing technology is integrated to the robot system to enhance the robot’s capability to work in a dynamic environment. It makes the robot system easy-to-use for the end user and yet operative with a human. Vision sensing is a vital sensing technology where the robot mimics human vision to guide itself through the complex process.

(Previous Answer)

In visual sensing, cameras optically sense the presence and shape of the object. A microprocessor then processes the image (usually in less than one second), the image is measured, and the measurements are digitized (image recognition). There are two basic systems of machine vision: linear array and matrix array.

10-STAND-ALONE MACHINES
Dictionary meaning is a machine capable of functioning indepently of a master computer either part of the time or all of the time.The stand alone machines are numerically controlled machines but with significant operator/machine interaction (p.1147) The operations performed typically have high part variety-meaning that different parts can be produced in a short time without extensive changes in tooling and in operations.
