Frame

• Need 4 pieces if 2x1 for base 
  
  • •  .100 or thicker = thick wall (Good for chassis for durability and high impact surface
• Bellypan
  • Has many grommit holes to allow for elec components to mount, and has holes for mounting onto chassis and save weight. 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)
• Mounting tubes integrated in the middle for mounting subsystems and increasing overall durability
  • Connected to core 2x1s by gussets
• 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)
