Work on OrcaImageGrabber library

Uses libdc1394 library to direct access hw. Uses the ptgrey example as a starting point. (uses libdc1394-2-rc7 and not the final version>>interfaces are different between rc7 and final v)

Fedora 9 uses juju instead of old 1394 firewire stack. had to get kernel patch from atRPM. 

Include lib1394, libtriclops and libpnmutils in "CMakeLists.txt" in src/components/imageserver to avoid undef references at run time.

IF ( DIGICLOPS_AND_TRICLOPS_FOUND )
        ADD_DEFINITIONS( -DBUILD_DIGICLOPS_GRABBER )
        INCLUDE_DIRECTORIES( /usr/local/include/digiclops /usr/local/include/triclops)
        SET( DEP_LIBS ${DEP_LIBS} ${OPENCV_LIBS} digiclops triclops pnmutils OrcaImageGrabber )
    ENDIF ( DIGICLOPS_AND_TRICLOPS_FOUND )

do the same for CMakeLists.txt in /src/lib/orcaimagegrabber. (actual src files are here) 

Single loop around the usual cubicles with lot of texture added on. Not exactly a rectangular path. (red-uvd,grn-odo,blu-lEKF)

klt_6ftrs: Good results with rippleSLAM v0.7. loop closure decreases the conservativeness and a ripple at 200th pose improves accuracy. Laser outline shows good consistency however laserEKF still has issues.

It is often useful to use a graphical format to view the distribution of the nonzero elements within a sparse matrix. The MATLAB spy function produces a template view of the sparsity structure, where each point on the graph represents the location of a nonzero array element.

For example,

spy(west0479)

Kinematic constraints are classically

divided into two classes: constraints

that can be integrated to yield constraints

on the position variables,

called holonomic constraints, and constraints

for which this integration is

not possible, called nonholonomic constraints.

A typical example of a nonholonomic

constraint is a wheel rolling

vertically without slipping on a surface.

The constraint on the allowable velocity

(the point of contact of the wheel

with the surface cannot slip in all

directions) cannot be integrated to

yield a constraint on the position of

the wheel. This nonintegrability is

intuitively clear, as illustrated by the

fact that an automobile can go anywhere

it pleases by suitable maneuvering.

(This example hints at the

intimate relationship between nonholonomic

constraints and controllability.)

Loosely speaking, mechanical

systems with holonomic constraints

can be reduced to lower dimensional

mechanical systems without constraints;

for systems with nonholonomic

constraints, this reduction is not

possible, and as a result some distinguishing

features arise
