3.2.3 - The Inspection Process

3.2.3 - The Inspection Process

Section titled “3.2.3 - The Inspection Process”

Objective: Learn how to navigate the official FRC Robot Inspection, understand the most common reasons robots fail, and execute a complete “Mock Inspection” in our shop to ensure we get our competition sticker on Thursday morning.

A robot that hasn’t passed inspection is just a very expensive paperweight. Before we are allowed to play in a single Qualification match, volunteer Robot Inspectors (RIs) will tear through our machine to ensure it complies with every rule in the manual.

Getting inspected early and passing on the first try is a massive competitive advantage. It gives our Drive Team time to practice on the real field while other teams are stuck in their pits grinding down overweight parts. This module teaches you how to guarantee we pass.

🚦 Step 1: The Inspection Mindset

Robot Inspectors are volunteers who want you to play, but they are obligated to enforce the rules. Your job is to make their job as easy as possible.

The “Big Four” Reasons Teams Fail Inspection:

  1. Overweight: The robot (without battery and bumpers) exceeds the 125.0 lb limit.
  2. Oversize: The frame perimeter extends beyond the max dimensions, or the robot is too tall.
  3. Illegal Bumpers: Plywood is too thin, noodles are the wrong type, gaps are too large, or the mounting brackets are flimsy.
  4. Electrical Hazards: The Main Breaker is hard to reach, wires are the wrong gauge (thickness) for their breakers, or battery terminals are exposed (not covered in electrical tape/heat shrink).

📝 Step 2: Pre-Competition Deliverables

We never go to a competition hoping we pass. We know we will pass because we inspect ourselves first. Complete the following three deliverables with the Pit Crew and your Subteam Lead.

⚖️ Deliverable 1: The Weight & Size Audit We must know exactly what the robot weighs before it goes into the trailer.

  • The Task: 1. Strip the robot down to its inspection state (take OFF the bumpers and battery). 2. Place the robot on the shop scale. Document the exact weight. (If it is over 123 lbs, we need to talk about a diet—competition scales can vary!). 3. Take a tape measure and physically measure the Frame Perimeter. 4. Measure the maximum height of the robot in its starting configuration.
  • Sign-off: Show the recorded weight and dimensions to the Lead Engineering Mentor.

🛡️ Deliverable 2: The Bumper Audit Bumpers fail inspection more than anything else in FRC.

  • The Task: Audit both the Red and Blue bumpers (or reversible covers) against the current game manual rules:
    1. Are the team numbers at least 4 inches tall with a 1/2 inch stroke?
    2. Are the pool noodles exactly 2.5 inches (nominal) and solid/hollow as allowed?
    3. Is the wood backing at least 3/4 inch thick and 5 inches tall?
    4. Mount the bumpers to the robot. Grab them and pull hard. Do they sag or shift? (If yes, they will fail).
  • Sign-off: Have the Pit Boss aggressively test your bumper mounts.

📋 Deliverable 3: The Official Mock Inspection FIRST publishes the official Inspection Checklist online a few weeks before events. We use the exact same sheet the inspectors use.

  • The Task: Print out the official FRC Inspection Checklist for the current season. Pair up with another student who did not work on your subsystem (they will have fresh eyes). Go line-by-line through the checklist and check off every single box. If you cannot check a box, you must tag the issue with a piece of blue painter’s tape.
  • Sign-off: Hand the completed (and fully checked) official sheet to the Lead Mentor.

🔄 Step 3: The Actual Workflow (At the Event)

When the pits open on Thursday morning, this is our exact playbook:

  1. The Scale Line: As soon as the robot is un-bagged/un-crated and bumpers are off, two students immediately roll it to the official inspection scale. Get weighed early before the line wraps around the arena.
  2. Sizing Box: Prove the frame perimeter and starting height at the inspection station.
  3. Pit Inspection: Return to the pit and put your name on the Inspector Whiteboard. An inspector will come to our pit.
  4. The Walkthrough: The Lead Pit Student answers the inspector’s questions, turns the robot on/off when asked, and points out specific components.
  5. Corrections: If the inspector finds an issue, do not argue. Say, “Thank you, we will fix that right now.” Fix it immediately, then ask them to return for a re-check.
  6. The Sticker: Once passed, the inspector places a colored sticker on our robot. We are now legal to play!

✅ Step 4: Pathway Deliverable

To complete this module, you must physically participate in preparing the robot for inspection.

Before submitting for review, ensure you have:

  • Participated in the Weight & Size Audit and recorded the numbers.
  • Verified the bumpers meet all manual requirements and mount securely.
  • Acted as the “Mock Inspector” using the official FIRST checklist on our robot.

Notify a Mentor: Let the Pit Boss know you have completed the mock inspection and are ready to interface with the real inspectors at the event.

🎉 Module Complete! You now know how to get the robot legally approved for play. Next, you need to learn how to connect it to the official FIRST Field Management System (FMS).
