	1. ~~Weigh Robot~~ (~~Done~~)		#Shooter seems ok; more rpm would help extend range (may have been done on 2/17 before ship).<br>
			#Gather seems ok, need more permanent outside guides; listed below.<br>
			#Plucker fingers seem too weak.  Can we add something inside to stiffen?<br>
			#Suggestion:  Shafts between pulleys could have pool noodles around to limit dropped belt movement. (if a belt falls off it won't go as far)<br>
			#Recycle ball (lotto) mode was a good feature.<br>
			#Back guides seemed to work well.  Maybe make wider.<br>
			#Rear hopper ball sticking points - ball above was pushing ball below away from plucker.  Suggestion to firm up rear hopper by moving lexan panels inside frame - completed on 2/17 before ship.<br>
			#Lexan velcro seemed too weak to hold rear panel in rear. Add more, upgrade if moving inside is not enough.<br>
			#Guides could be made out of 2 inch wide strips of lexan rather than aluminum tube. Another suggestion was to use fishing line.<br>
			#Ball holding capacity:  Two rows in rear limits to 10 balls (est).  Not divided capacity approx 14 but runs the risk of nesting / jamming. Belived that two orderly rows would unload quicker with less ball jostling.<br>
			#Belts fall off way too frequently.  <br>

	~~     ~~ with ~~improvements (divider) 120~~.~~82 lbs~~		Options:  (a) PVC Roller (HFL Design) One wide belt or a pair of belts.  Concern with tracking - was ruled out as option.<br>

	~~Naked - 111~~.~~86 lbs~~		(b) Scrap existing pulleys.  Use shaft only with end stops. <br>

	~~+ Lexan~~ - ~~114~~.~~86 lbs~~		(c) Add more round belts - 1 1/2 to 2 inch center distance beween belts. (Tested on 2/17/09).<br>

	2.  ~~Weigh Rear Hopper Ad Hoc Guides~~		== To Do Before Ship  (D. Vadas List)<br> ==

			6. Notch Trap Door Motor Reservoir Guide<br>

			== To Do After Ship (D. Vadas List)<br> ==

			1.  Get 50+ hardened 1/4 inch washers - Tom and Mike Wolf have started collecting (in purple box, mechanical shelf, eye level)<br>

			2.  Make new gathering center divider<br>

			Added - T. Cavaliere<br>

			3.  Make new lower outside ball guides - we cut off the chained together zip ties.<br>

			== To Do at RIT (D. Vadas List)<br> ==

			1.  Vibro-tite drive wheel screws.<br>

			2. Mount new gathering center divider (if needed)<br>

			3.  Mount nylon skid pads to the gathering "Cow Catcher" <br>

			4.  Adjust CCW Trap door limit switch to prevent overtravel.<br>

			5. Improve hopper lexan at top. (Velcro added on 2/17/09 - able to stop a homemade orbit ball from flipping backward over top)<br>
