Post-Mortem

What Worked

• We won!
• Barrier Crossing
• Pivot Drive - but there are ease-of-use issues
• Shooter - but did not use speed control
• Manual aiming using camera - automatic aiming not tried
• Lift logic seems okay

341 said that they picked us as an alliance partner because:

1. Ability to cross the barrier
2. Autononous
3. They trusted us (the drive team)

Further, they inicated that we were:

• Not arrogant
• Tenacious
• Coaches talk

What didn't

• Bumpers

• Fell off (fixed)
• Too big (pool noodles too large diameter)
• Too high
• We shear mounting rivets (change to steel)
• runs over balls

• Bridge Arm

• Did not allow us to get the bridge down to drive on
• Eye-pokers should be addressed

• Ball Lift

• Excessive compression
• Rails not anchored at top and actually crossed at one point
• Beater bar too high & slow
• Guide rails / funnel did not work - balls went under

Improvements needed

• Easier (more intuitive) to drive & operate
• Can we measure ball compressibility?
• Lighter, more transparent covering
• Auto aiming needed (needs to be fast & accurate)
• Shooter speed control needed
• Need a stronger and more reliable autonomous suite for Lenape

Action Plan

• Get deux working - Featherman & Deaver this week

• Retest 4-slot cRIO
• Use 8-slot cRIO if 4-slot not working

• Set up meetings with different focus - Mechanical / Programming / Training - w/ cross coverage to address issues
• Identify where mass can be reduced - Kellom
• Get vision processing & targeting working - Programming
• Develop a bridge arm that works - McKown & Kulik
• Fix Lift system - Deaver
• Robot must be mechanically/electrically complete prior to arrival at Lenape
• Rationalize driver controls
