a quick look at some parts

The four frame washers made out of 6061 1/16th sheet and
made on the water-jet

These are the frame connectors, the main pieces holding our
frame together and used to locate our bot into the slot

The motor blocks were made on the mill and will position
the motor for our screw drive

Shown above are the three types of linkage pieces.  The
right most pair are is the primary linkage arms and are
connected to the power screw.  They were redesigned to be
wider after some FEA testing.  The middle pair are the
secondary linkage arms, they help keep the linkage parallel
and support a reduced portion of the load.  The left most
pair is the bottom linkage.  These members make contact
with the flipper and open it.  All the linkage members were
made on the water-jet

These small pins are only 1/4 inch long and at most 3/8 inch
diameter! Due to the tight confines of the slot they will allow
the conveyor belt system to pass through the linkage.

These pins will locate the rack and pinion in the conveyor
lowering system.

This pin is the main pin in our linkage system, it is located
within the front of the bottom linkage.

The pins shown above are located at the top of the linkage,
they connect the linkage system to the frame.

Here is Steve working with the laser cutter.  A quick fact about
Steve, he's never seen without his red wings hat.   Some
say it is the source of power for his engineering wizardry.
