Linkage assembly and testing (MCM)

The frame assembled with the connectors.

A better look at the linkage system
installed  in the frame.

A side view of of the bot, the tape is constraining the frame until other
systems are installed.

These are the mounts for the motor
to the power screw.

Colin and Steve working on the motor for the power screw.

The bot constrained in the slot, in starting position.  We connected the
control system to the bot, and everything is working great!

Just after starting, the bot is pushing open the lever.  The power screw
design can overcome very large opposing forces and still open the lever.

The bot holding the lever open... Success!  Another interesting aspect of
power screw design is that opposing forces will not back-drive the system,
that is to say that the design is self-locking.
