For starters I just want to say that everyone is doing a great job.  We are 
moving along with the design at a good pace, and I'm confident you guys are 
going to have an awesome robot this year.

1) The new frame has been dropped off at superior joining at I am waiting for a 
status report on when this can be done.
2) Woodward's prototype department is making the brackets for the robotic arm.  
These are expected Tuesday next week.
3) Extra chain, links and sprockets have been ordered.  The order is still 
being processed at andymark.  I am expecting this Friday or Monday.
4) I ordered 2 x 12 inch long pneumatic cylinders from bimba and 1 x 10 inch 
long.  No word yet on whether we can get a 22-24 inch cylinder, but my guess is 
that the ¾" diameter is too small to support such a long shaft.  Between these 
cylinders and the 6 and 8 inch ones that we have, we should have plenty of 
options for the claw, wrist, and minibot deployment.  We need to evaluate 
whether we have enough solenoid valves (and the solenoid breakout?) and order 
parts soon if needed.  Also if we need another size of cylinder we can order 
them.
5) I ordered extra tetrix parts in case we want to build another robot or have 
extra gears for the current design.  Parts are on back order, so this may take 
3 weeks or so... better late than never (maybe a good design improvement 
project in between WI and the championship??? Even if we are the fastest in 
Wisconsin, we'll need to get faster for the champs).
6) The 256:1 gear box from banebots had a 5 day lead time, this should be 
shipping soon (gearbox for main arm pivot).
7) The magnets for the minibot shipped later yesterday and should be waiting 
for us for Thursday.


Some other things we need to finish working out:
-Integrate the arm design in to the CAD model of the frame.
-Finish designing the minibot deployment and test it in the cad system using 
the robot and playing field.
-Experiment with minibot configurations, magnet hold (careful not to pinch your 
fingers!), wheel configuration, and gear ratios
-Complete claw design (constrained to overall length proportions to the wood 
prototype we built)
-Design wrist actuation or deployment.
-Experiment with line sensors so programming team can get them working.
-Gearbox mounting bracket for robotic arm (mount to back side of main arm 
supports (simple plate bracket).

Once these things are done, we will be in a position to mostly plug and chug on 
the machining and assembly of the bot.

Keep up the good work!

-Adam
