I suppose it could be faked but it looks OK to me.

It seems legit, cuz there are so many motors...I bet the machine cost
hundreds or something. Maybe it was the same position, like off-camera the
machine scans it?

It's=C2=A0CubeStormer II (http://www.speedsolving.com/wiki/index.php/List_o=
f_cube_solving_robots#CubeStormer_II). =C2=A0It uses a 2-phase method for s=
olving cubes move optimally (not Fridrich) as used prominently by Cube Expl=
orer 5.00 (http://kociemba.org/cube.htm). =C2=A0It orients all the pieces, =
and then permutates all the pieces using only half turns on the left, front=
, right, and back faces, and quarter or half turns on the top and bottom fa=
ces. =C2=A0This makes it easy for the robot's four arms' graplers to be abo=
ut to turn the cube quickly without letting go of the cube. =C2=A0I had mad=
e a human thistlethwaite algorithm for solving the cube in under 40 moves (=
HTM) and had worked on (and given up on) making a human 3-phase method for =
fewest moves that involves orienting the edges intuitively, orienting the f=
ront and back layer corners or top and bottom layer corners or left and rig=
ht layer corners optimally, and then permutating all pieces optimally for a=
n average 25
moves HTM (half turn metric). =C2=A0I also have a LEGO=C2=A0Mindstorms=C2=
=A0NXT robotics kit (bought for about $400) which is used for the robot, bu=
t I only have one and CubeStormer II uses two NXT computers with six indivi=
dual servo motors while I only have three individual servo motors. =C2=A0Al=
though I don't have a camera, the additional NXT computer, and three additi=
onal servo motors, I managed to make a robot that solves the cube in less t=
hat 3 minutes on average with a light sensor (not colour sensor) that obser=
ves the shades of the stickers. =C2=A0For a simple cube solving robot that =
uses the LEGO Mindstorms NXT robotics kit , go to=C2=A0http://tiltedtwister=
.com/tiltedtwister2.html =C2=A0There are also other robots that solve bigge=
r cubes and puzzles such as the megaminx and can be found at http://www.spe=
edsolving.com/wiki/index.php/List_of_cube_solving_robots.

Hope this helps,
Brandon.
