# Application Examples

Most FRC robot mechanisms follow similar build styles and fundamentals. This section goes over subsystem archetypes and modular components used to build a functional competition robot.

## Core Robot Subsystems&#x20;

**Chassis & Drivetrain:** The foundation of any FRC robot. Here you'll find info about the Kit of Parts chassis, which uses a parallel plate construction, and swerve drive systems, which utilize corner modules bolted to drive rails.

**Intakes:** Using linkages or arms for deployment, consider material for impact resistance and wheel type for control.
&#x20;You may consider using mecanum wheels to center game pieces and compliant wheels for positive grip.

**Launchers:** The three primary types are flywheels, catapults, and linear punches. Each comes with variability in shot consistency and complexity.

**Arms:** Common for moving objects between heights; common to FRC are single-joint and complex multi-jointed arms.

**Elevators:** Highly complex subsystems often using COTS bearing blocks and box/punch tubing for reliable vertical movement.

**Climbers:** Often a "wild card" design, these are commonly implemented as telescoping elevator systems.
