FTC DECODE Flywheel Launcher Simulation

Web visualiser application for robot launcher physics in the FTC DECODE Season (2025-2026) made by team Clockworks #19075 from Bucharest, Romania.

Key features

• Dynamic charts and indicators for launcher parameters:
  • trajectory plots
  • field view display
  • impact error calculation
  • shot confidence score
• Real time trajectory simulation accounting for gravity and basic drag force (linear velocity dependent drag)
• Interactive controls for launcher parameters:
  • Flywheel velocity slider
  • Launcher heading compass
• Manual drop-down inputs for fine tuning parameter values
  • Tweak-able measurement units

Tech Stack

• Astro - Server-Side-Generation (SSG) framework using "islands architecture" for hydration
• React - interactivity
• Typescript - static typing
• Plotly.js - charting and graphs
• Nanostores - state management
