Q.6)

a) Automated guided Vehicle

Ans:- An automated guided vehicle is a mobile robot that follow markers or wires in

the floor, or uses vision, magnets, or lasers for navigation. They are most often used

in industrial applications to move materials around a manufacturing facility or

warehouse. Application of the automated guided vehicle has broadened for the past.

The AGV can tow objects behind them in trailers to which they can autonomously attach.

The trailers can be used to move raw materials or finished product. The AGV can also

store objects on a bed. The objects can be placed on a set of motorized rollers (conveyor)

and then pushed off by reversing them. AGVs are employed in nearly every industry,

including, pulp, paper, metals, newspaper, and general manufacturing. Transporting

materials such as food, linen or medicine in hospitals is also done.

An AGV can also be called a laser guided vehicle (LGV).

Lower cost versions of AGVs are often called Automated Guided Carts (AGCs) and are

usually guided by magnetic tape. AGCs are available in a variety of models and can be

used to move products on an assembly line, transport goods throughout a plant or

warehouse, and deliver loads.

Wired :-

A slot is cut in to the floor and a wire is placed approximately 1 inch below the surface.

This slot is cut along the path the AGV is to follow. This information is used to regulate

the steering circuit, making the AGV follow the wire.

Guide Tape :-

AGVs (some known as automated guided carts or AGCs) use tape for the guide path. The

tapes can be one of two styles: magnetic or colored. small pieces of magnetic tape may

be placed to change states of the AGC based on polarity and sequence of the tags.

b) Rapid Tooling

Ans :-





C) AI in Design

Ans:-



D) Application of RPT

Ans :-





E) Role of CAD/CAM in CIM

Ans :-
