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

Bridge Arm Changes

The original Bridge Arm was entirely replaced with a new arm. The original arm was passive (robot momentum provided the motive force to lower the bridge) while the new arm is active (the arm provides the motive force).
