Overtime

Team 2637 introduces its newest and most advanced robot yet! The name we chose for the CHARGED UP season is Overtime. To the left is an image of our unfinished robot, and it serves as a sneak peek of our engineering and design development so far this season. Below is a cad model.

​Intake 

• Polycarb Sides 
  
• 2 Falcon500 motors
  
• 4 Rollers
  
• Star wheels and compliant wheels
  
• HTD timing belt transmission system for rollers
  
• Sprocket and chain transmission for pivoting
  

​Indexer 

• 2 PolyBelt conveyors transport game pieces
  
• 8 Vertical compliant rollers to center cones and cubes
  
• Reorienting bar for backward cones
  
• 5 NEO 550 motors
  
• Color sensor determines game piece type
  
• Break beam sensors determine cone orientation
  

Arm

• Elevator on pivot design
• Rotation:
  • Dead-axle
  • Two Falcon 500’s, each into a 1:28 VersaPlanetary, then into a sprocket reduction, then bolted to the arm
• Rigging:
  • Continuously rigged 
  • Extension: a NEO into a sprocket reduction powers a spool, retracting and extending Dyneema
• Construction:
  • 1/16” Aluminum box tube
  • Bearing blocks are integrated with gussets, saving weight and space
• Strategy:
  • Scores all levels
  • Stows vertically, scores are ~40* angle

Outtake

• 4 Polycarb gripper plates
• Modified pool noodles for maximum friction
• 5” Stroke length piston for gripper actuation
• Bearing plates allow box tube carriage to glide along Arm
• Tensioner spring keeps carriage level

Drivetrain

• Swerve drive moves in any direction
  
• 4 Modified SDS MK4i swerve modules
  
• Falcon500 motors for driving
  
• NEO motors for steering
  
• 1/16” Thick box tube frame
  
• 29” by 29” square layout
