Systems

  • Gearboxes
    • Motors spin at very high speeds but produce very little usable torque (generally).
    • Gearboxes have sets of gears with varying sizes.
    • What do gearboxes do?
      • Gearboxes allow you to change the axis of rotation for a gear
      • They also allow you to modify gear ratios.
      • For example, if you have a 5:1 gear ratio, you'll be able to make it so that by the time one gear spins 5 times, the other spins once.
    • Why is a gearbox needed at all?
      • To change rotation axes
      • Transfers energy from one device to another.
      • Increases torque and reduces speed
  • Motors
    • There are several types of motors legal for FRC use:
      • CIMs - fat, black, and really big
        • Used primarily for wheels
        • Bag motors - similar in appearance to CIMs but smaller and slightly less powerful
      • 775 pro - these are very versatile in their use and are almost always used with the versaplanetary gearboxes.
    • Actuators
      • Type of motor that controls a mechanism that is inbuilt.
      • Makes use of motor and threaded axle for one directional movement.
    • Pulleys and Sprockets
      • Pulley: Pulleys reduce load on motors so that components do not have to undergo as much strain.
      • Sprockets: Gears for chains.
