Robotics Mechanical design Competition strategy Iterative testing

Project Story

In VEX, every design choice had a tradeoff. I led the build and coding, but the bigger lesson was learning how to decide what mattered most when the robot had to be reliable, legal, drivable, and finished on time.

Why I Built It

VEX competitions require robots that are mechanically robust, strategically versatile, and rapidly iteratable within strict size, time, and rules constraints.

What I Built

An iterative design-build-test cycle with modular subsystems, essential-feature prioritisation, driver practice protocols, autonomous routines, and data-driven strategy refinement.

What I Did

  • Team captain and lead engineer
  • Designed drivetrain and game-specific mechanisms
  • Led robot coding and autonomous routine development
  • Coordinated build schedule and competition preparation
  • Led driver training and match strategy

How I Built It

Build Flow

Game analysis -> concept design -> prototype -> test -> competition iteration loop.

How It Works

The robot combined a reliable drivetrain with game-specific mechanisms, programmed autonomous routines, and was continuously refined based on scrimmage and competition performance data.

Hardware

  • VEX V5 system
  • Custom mechanisms
  • Competition field elements

Software

  • Robot programming
  • Autonomous routines

What Was Hard

  • Designing mechanisms robust enough for repeated competition stress
  • Balancing autonomous reliability with driver control flexibility
  • Optimising build time against performance requirements
  • Choosing which features to cut when time, size, and reliability conflicted

Demos and Build Notes

Results & Impact

  • Top 5 Switzerland - VEX Robotics
  • Consistent tournament performance across the season
  • Strong team coordination and engineering documentation
  • First-year national placement gave the team a strong competitive foundation

What I Learned

  • Reliability in competition often beats theoretical maximum performance
  • Driver practice is as important as mechanical design
  • Strict constraints make prioritisation an engineering skill, not just a management task

Next Steps

  • Apply competition robotics experience to university projects
  • Explore autonomous navigation with computer vision
  • Document build process as portfolio case study
