Drivetrain:
6WD w/ AM servo shifters
Plenty of ramp clearance as seen below:

Arm:
AM CIM gearbox & FP- Quick auto-positioning 2 pivot joint design

Performance Videos:
Check out videos of FLR Highest Score of 158 to 0 &
FLR High Score of 158
Buckeye High Score of 258 to 34 in qf4m2
Buckeye Highest score 258

FLR #1 Alliance Quarterfinalist (Rank#3)
Buckeye #5 Alliance Quarterfinalist

High Tube Score Average.:)

Another Very Robust design - come see the pit crew for any assistance since they were getting bored... Hence the FLR J&J Sportsmanship award and many new friends at Buckeye!

Sorry I had to fix a link for one of the videos

uses up to 118 in/s to get where defence is needed then drops to lower ratio inorder to maintain torque and efficiency while pushing to prevent stalling

Autonomous
drive to side of rack to be closer for Defence

Drive team
both drivers 2 years of experience
coach has 3 years of experience

Team 1902- The Exploding Bacon
Florida Finalists #2 Seed Ranking Score ~16
Imagery award
7-1-0 Qualification
W, W Quarterfinals
W,L, W Semifinals
W, L, L Finals
Vegas SemiFinalist With #7 Seed Ranking Score ~29
GM Industrial Design Award
4-5 Qualification ( 10 pts higher ) ( Technically 5-4 but due to a reversed call which was later clarified that we won the match but never credited to us )
W,W Quarterfinals
L,W,L Semifinals

Drivetrain6 wheels with lowered center wheels
6 inch Andy Mark Performance
2 speed AM servo shift integrated into Frame
~5 ft/s low and ~12.5 ft/s high

Arm
Can reach all 3 tiers quickly
4 Bar linkage with gas strut stabilizer, Easily Controllable and caps over many 4ft. robots. Controlled by designated presets and modified positioning with a joystick.

Gripper
Simple Claw Mechanism actuated by Globe Motor, very reliable and holds tubes well.

Points of success
Devestating scorer when left open. ( With matches with light defense caps 6-10 tubes ) With 1 -2 defenders our average drops to 4.25, 4.7 if you don't count a match where we flipped. (Vegas Average not sure about Florida )
Climbs ramps well
Powerful/Fast drivetrain
Gripper good, but could be better, occasionally hard to get tubes while under defense.
Able to cap and remove spoilers with ease.
26/30 Autonomous Caps in competition this year
Reliable, Reliable, Reliable. Never Missed nor broke in a match ( Knock on Wood )

Points of Needed Improvement:
Play best on near side of the field, the other side seems sometimes out of our realm.We need to get better on the other side.
Avoiding heavier low robot defenders rather than trying to always power through them.

Overall Assesment:
Good robot but have some weaknesses, it will be interesting to see how the match algerithm works at champs. Most say we can't play through defense and our performance does suffer under defense. At vegas we averaged ~ 4.25 caps a match and atleast 1 robot on defense per match. We had one match without constant defense ( just intermittant 1 defender vrs 2 good cappers ) in which we put up 8 tubes. ( 1 keeper 6 ringers 1 spoiler )
