Consider the following characteristics:

$$1.$$ Single machine tool.
$$2.$$ Manual materials handling system
$$3.$$ Computer control.
$$4.$$ Random sequencing of part to machines.

Which of the above characteristics are associated with flexible manufacturing system?

Given that the notations of robot joints are $$L$$-linear, $$O$$-orthogonal, $$R$$-rotational, $$T$$-twisting, and $$V$$-revolving, the anatomy of a polar configuration robot is described by the alphabetical string

For machining the circular arc shown in the figure below on a $$NC$$ machine, the interpolation parameters $$(I.K)$$ and the incremental movements in the direction of the $$X$$ and $$Z$$ axes are programmed as
