Ramp surface was removed and recut to 37" long x 11" wide
intake rotation plates and inside slide bearings attached to carriage
feeder arms assembly made significant progress
assembled another 5:1 gearbox & attached
changed a few spacer dimensions ( 1/8" between bearing & pulley, 1/4" between wheel & bottom plate) because of lack of 1/16" spacers
prepped intake hinges (insert bushings, tapped, cut gears to fit)
made elevator chain attachment to second stage
Challenges
assembly guide would be extremely helpful next year (or for comp) because people were often unsure of how things are assembled (both the steps required and finding correct parts) even with CAD
trouble finding 1/16" spacers
Work for Next Meeting
make practice bot functional ASAP!
elevator
make sure carriage glides smoothly inside second stage
supports from crossbar near bottom need to be attached
cut & tap both ends a 1.5" & a 1.8" shaft for sprockets
attach top crossbar, chains, motors
test electrically when assembled
intake
If the one side works, Bob will get second back channel routed
one side arm still needs standoffs, belts and washers for the bolts attaching the motor
attach to back channel & hinge on elev
ramp
"The two sections are presently held with 3 rivets. Rivets should be added along the side beams. I should have taken a picture but there are 3 hole widths of perforated aluminum covering the 38" long pieces of extrusion. Rivets should be placed in the middle set along the 38" long pieces. No need to rivet onto the middle piece under the ramp surface. Also, don't rivet anywhere in the 12 inches of tubing closest to where it mounts to the robot. The presently riveted section is the end that will contact the floor. The total weight of the Perf Aluminum for a single ramp is 1.9 lbs. Total robot weight reduction is 5 lbs. Total theoretical weight of comp bot with new ramp surface plus parts we need to add: 127.59." - Bob
