Version 3.0
Specifications:
6 wheel, 4 hi speed motor drive
1:9.375 torque ratio six bar linkage
2 side rollers with top roller
Pros:
Excellent intake, could intake BuckyBalls and Big Balls without requirement for a wall (after some tweaking)
6 different autonomous modes for various scenarios
Anti Tip pegs to prevent tipping
Cons:
Lift only rose to 22 inches, 2 inches shy of the stash
Drive could only go over bump forwards not backwards (Struggled to go over forwards)
Intake was too wide and buckyballs changed orientation while in it
Cortex port 10 blew out midway through the second competition

Version 4.0
Specifications:
4 motor, 4 wheel hi speed drive
4 motor 1:7 six bar linkage
2 intake rollers with hi roller for large balls
Pros:
Extremely easy to get over bump either way
Buttery smooth lift
Cons:
Often found ourselves chasing after buckyballs
No autonomous due to potentiometer glitches
Pins of motors came off due to slightly careless wiring (Note to self: Zip ties instead of tape)
Need better marketing to potential alliance partners
