When

  1) 2x1s for the base (Qty - 4)
  

  2)

  • Bellypan
    (Qty
    • - 1)

      3) Mounting tubes (Qty - 1 or 2)

      Note - Wall thickness of .100100" or thicker = thick wall (Goodgood for chassis fordue to durability and high impact surface

    resistance)

• Bellypan

  • Has manysmall grommitholes in certain areas known as grommet holes to allow for elecelectrical components to mount, and has holes along the perimeter for mounting onto chassischassis. All bellypans have a cut extrusion pattern along the surface which saves weight and savemakes weight.it Knownlook nice, which is known as pocketing
  • • Laser cut by sponsors
    • Typically 1/16" to 1/4" in thickness
    • Thicker bellypans have smoother driving due to lower center of mass (COM is VERY important)gravity

   

  Mounting Tubes

  • Mounting tubes are integrated ininto the middleframe design for structural support and for mounting separate subsystems andlike increasingshooters, overallintakes, durabilityclimbers,
    • Connected to core 2x1s by gussetsetc.

  

  • Place battery first when designing drivetrain as it is the heaviest so you can take COM into account (important for deciding how smooth your robot can drive)
  • Tungsten sheets are heavy and good for COM, but very expensive (Insert mcmaster carr tungsten sheet price pic)
  • When designing your drivebase, your main goal should be maximizing COM while maintaining efficient mass to incorporate toher subsystems in the future
    
  • Acceleration is prioritized in games which require lots of change of direction and a need for a fast topspeed accumulation
  • Tall robots which have a need for speed require heavier drivebases to maintain balance
  • If geared too tall, it means it takes too long to reach topspeed
    
    • Robots geared too high will do better with pushing (kinda like torque) while bots geared for top speed won't (Speed is inverse of torque)
