Assembly 4 - Gearboxes
Gearboxes are a core component in FRC. They are used to take the very high rotation low torque motors used in FRC and translate that rotation into slower, higher torque rotation that can be used to drive wheels, elevators, and end effector mechanisms such as intakes. An understanding of how gearboxes work and how to assemble, lubricate, and troubleshoot them allows for more advanced robotics tasks to be performed easily.
Assembly 5 - Pneumatics
What motors are to rotational motion, pneumatics are to linear motion. They are used widely in FRC, and an understanding of how they work, how to attach them to the robot, and how to plumb them is a large part of FRC assembly. Information such as when to use thread tape on fittings, how to troubleshoot leaks, and how the core pneumatic system functions are also important.
Assembly 6 - Shafts and Spacers
Shafts are used in FRC to transmit rotation power, or to allow the free rotation of a part. They are typically used in conjunction with bearings, spacers, shaft collars, and/or bolts on the ends to secure the mechanisms to them. Both hexagonal and cylindrical shafts are used commonly in FRC. Assemblers will learn techniques for assembling shafts quickly and accurately, and how to secure them into place.
Assembly 7 - Bearings
Bearings are used widely in FRC and allow shafts to rotate rapidly and with minimal friction. Ensuring that they are put into place, spaced correctly, and preloaded will lead to excellent robot operation. A failure to perform these tasks can lead to the robot performing poorly or breaking. Advanced assemblers will be able to discuss with the design team how there might be a need to redesign systems if they run into issues.
