Drivebase 

• MK4i swerve drive specialty modules
• L2 gearing kit
• 29in X 29in frame dimensions
• 1/16th inch box tubing drive frame
• 2 1/16th inch box tubing cross bars
  • Crossbars are utilized as mechanism mounting locations and provide additional rigidity to the frame
• Steel blocks added to the frame
  • Lowers overall robot center of gravity

Elevator

• The elevator is a single stage chain elevator
• The frame is constructed out of 1/16th inch box tubing
• The frame is mounted to the boxtube using 2 ¼ inch aluminum plates
• Two types of elevator supports
  • The back brace prevents warping and bowing in the center of the elevator
  • The poles prevent warping at the top of the elevator
• The total travel distance along the elevator is 48 inch
• The elevator is at a 63 deg angle with the horizontal
• The elevator is driven by 1 Falcon 500
• The gearbox provides a net reduction of 6.3297
• The bevel gearing system allows for more efficient packaging of the powertrain system in the constrained space below the resting location of the area
• There is a single continuous #25 chain which runs the entire length of the elevator
  • There is a single chain tensioner which runs opposite to the arm
  • The #25 chain is connected to the arm mechanism using 3 bolts which run through the chain linkages

Arm

Intake

• The arm is a single stage telescoping timing belt system
• The outer stage is 1/8th inch 2in X 2in box tubing
• The inner stage is a 1/16th inch 1.5in X 1.5in box tubing
• The total travel distance of the telescoping arm is 10.25 inch
• The telescoping arm is mounted to the carriage using 2 ¼” aluminum plates
• The telescoping arm is powered by 1 Falcon 500
• There is a provided net reduction of 9.3333
  • The initial reduction is provided by a 7:1 VersaPlanetary
  • The additional reduction is provided by a belt reduction
• The arm extends using a 9mm HTD timing belt
  • The timing belt is secured to the inner stage using a 3d-printed part that matches the belt profile
• The carriage is constructed of a pair of 1/16th inch box tubing
  • 4 sets of elevator bearings on each side (2 horizontal and 2 vertical) guide the arm along the elevator
• The carriage is linked to the arm structure using two ¼” aluminum plates
  • This also serves to mount the Versaplanetary

• The main structure of the intake is made of ¼” polycarbonate
• The rollers are made of ⅛” polycarbonate wrapped in a silicone rubber tubing
• The main structure of the intake is connected to the hex-shaft using a versahub
• There are 3 total rollers 2 of which will always been engaged with the game object
• The rotation of the system is powered by 1 Falcon 500
  • There is a provided net reduction of 8.1667 for intake rotation
• The rollers of the system is powered by 1 Falcon 500
  • There is a provided net reduction of 2 for all rollers
• The use of an infinity belt will cause pairs of rollers to spin in opposite directions according to what is being collected
