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:
- Ability to cross the barrier
- Autononous
- 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).
