The Capture CIS links
component information, such
as PCB package footprint
data or simulation behaviour
data, with the circuit symbol in
the schematic.When exported
to other tools in the
OrCAD, the data stored in CIS
is also transferred to the other
OrCAD's Layout Engineer's
Edition gives functionality and
flexibility to engineers by
enabling them to define
placement, perform critical
routing, review designs, and
design complete circuit boards
where autorouting is not
Manual Robot is the one in which
the human controls the robot
using a joystick or switches. It is a
manipulator designed to perform
a variety of tasks.
The major building blocks of this
project are Regulated Power
Supply, Microcontroller based
Control Unit, Robot Mechanical
The micro controller is also interfaced with few
DC motors in order to move the robot in
different directions. ON and OFF of DC motors
depends on the direction it has to move which
is the complete responsibility of the controller
to take those intelligent decisions.
