Lesson 7

Robot Subsystems & Technical Pages

How to document each part of your robot clearly and effectively.

This lesson is all about documenting your robot's individual subsystems and technical components in a way that makes sense to judges.

What Are Subsystems?

Subsystems are basically the individual mechanical, electrical, and software parts that make up your robot. Each one serves a specific purpose and plays into your robot's overall performance.

Typical Subsystems

Drive(train) System

How your robot moves: wheels, motors, gearing

Intake System

How your robot collects game elements

Scoring Mechanism

How your robot scores points

Hanging / Climbing

How your robot hangs or climbs (if applicable)

Control System

Sensors and electronics that manage everything

How to Document Each Subsystem

For each subsystem, include:

Purpose

What does this subsystem do?

Design Evolution

How did it improve throughout the season?

Components Used

Motors, sensors, materials, etc.

Performance Metrics

Speed, reliability, efficiency numbers

Challenges & Solutions

Problems encountered and how you fixed them

Allocation Guidelines

Typically, Robot Subsystems take up 3-5 pages of your portfolio. How many pages you give each one depends on:

Complexity of each subsystem
How much it evolved during the season
Importance to your team's strategy
How unique or innovative your solution is

Sample Subsystem Page

Here's how to lay out a single subsystem's page - start with a big image of the current design, then show your iteration timeline below:

Large hero image of the current design dominates the top
Brief text explains purpose and key design choices
Timeline shows each iteration with thumbnails and dates
Specs table gives judges concrete, quantifiable numbers
Pro Tip: Use CAD renderings and photos to show your subsystems from different angles. Make sure each image has a clear caption explaining what judges are looking at.
