This is an old 6-legged walking robot that used
to be controlled by an RC Car base and an RCX
driving two 71427 gearmotors per side.
I have removed these in order to use the Power
Function elements.

The 24-tooth cogs are turned by the motors and
these turn the larger cogs that move the middle
leg each side in its slider.  The rods move the
front and back legs in opposition to the middle
leg.  This means that the robot moves forward
twice as much as the middle leg is raised and
lowered - more efficient than some other ways
of building it.

The front and back legs have sideways wheels.
This means that the robot can turn with all 3
feet on one side being on the floor - it will
still spin around the middle foot.  You just
have to make sure the legs are aligned well
before walking straight afterwards because it
can buck if the left and right legs are not
opposed.

The images are now released with permission from
TLG, since the Bulldozer 8275 has appeared at toy
fairs around the world.
