Mechanical, Build & PneumaticsModule 11 of 12

Advanced Techniques & Case Studies

Once you can build a working mechanism, this module shows you how the top teams make them fast, light, and bulletproof. We go deep on system characterization with SysId, simulation-driven design with WPILib physics models, motion profiling for crisp superstructure moves, weight-and-stress-driven structural design, and real Open Alliance case studies (FRC 6328, 1678, 2910). The emphasis is on the engineering judgment behind elite robots: choosing reductions from a torque-speed analysis, validating a design in CAD and sim before cutting metal, and packaging serviceable, manufacturable mechanisms. Everything cites real tools, real teams, and real parts.

Advanced Techniques & Case Studies closes the Mechanical, Build & Pneumatics guide as module 11 of 12, after Common Mistakes & Troubleshooting. Its 5 lessons are about 150 minutes of the guide's ~21 hours.

5 lessons

01Characterizing Any Mechanism with SysIdUse WPILib SysId to empirically measure kS/kV/kA (and kG) for drives, arms, and elevators, then deploy the gains for accurate feedforward control.30 min read

02Simulation-Driven Design with WPILib Physics ModelsValidate a mechanism before cutting metal using WPILib's physics sim classes (DCMotor, ElevatorSim, SingleJointedArmSim, FlywheelSim) and CAD-derived inputs.32 min read

03Motion Profiling and Superstructure CoordinationUse trapezoidal profiles and coordinated state machines to move multi-DOF superstructures fast, smooth, and without self-collision.30 min read

04Designing for Weight, Stiffness, and ManufacturabilityMake mechanisms light and stiff: load-path thinking, pocketing, dead vs live axles, COTS standardization, and serviceability for fast field repairs.30 min read

05Case Studies: Learning From Open Alliance RobotsReverse-engineer elite mechanisms (6328 A-frame pivot, 1678 flywheel shooter, 2910 dead-axle pivot) and use Open Alliance CAD/code to accelerate your own design.28 min read
