Standard Operating Procedure: VEX Robotics Competition Inspection

This Standard Operating Procedure (SOP) outlines the mandatory inspection protocol for VEX Robotics competition robots. The purpose of this inspection is to ensure compliance with the current VRC Game Manual, verify student safety, and guarantee a level playing field for all competitors. Adherence to this checklist prior to arriving at the official inspection station will minimize wait times and ensure your team is ready for qualification matches.

Section 1: Physical Robot Configuration

• Size Constraints: Ensure the robot fits within the 18" x 18" x 18" starting size box. Note: The robot may expand after the match begins, but it must start within these bounds.
• Weight Limit: Confirm the robot does not exceed the weight limit if specified by the current season’s game manual.
• Safety Audit: Ensure no sharp edges, burrs, or exposed metal are present that could cause injury to operators or damage to the field.
• Stability: Verify that the robot is stable and does not leak fluids or have loose components that could fall off during gameplay.

Section 2: Electronics and Control Systems

• Controller Pairing: Ensure the V5 Robot Brain is paired with the designated V5 Controller.
• Firmware: Verify that all V5 components (Brain, Motor Controllers, Sensors) are updated to the latest firmware version via the VEXos Utility.
• Battery Security: Ensure the V5 Robot Battery is securely fastened and the clip is fully engaged to prevent dislodgement during impact.
• Wiring Management: Ensure all wires are neatly managed with zip ties or cable clips, avoiding pinch points or loose strands that could get caught in moving parts.
• Emergency Stop: Demonstrate that the robot can be disabled immediately via the controller if required by the referee.

Section 3: Legal Parts and Fabrication

• Component Verification: Confirm that all parts used are official VEX V5 components or legal non-VEX parts as defined in the "Legal Parts" section of the game manual.
• Custom Parts: Ensure any custom fabricated parts (e.g., 3D printed components or non-VEX raw materials) meet the specific size and usage limitations defined in the current manual.
• Pneumatics (If Applicable): Check that all pneumatic tanks and cylinders are official VEX components and that the system pressure does not exceed the allowed PSI limit (typically 100 PSI).
• Motor Count: Verify that the total number of motors on the robot does not exceed the maximum allowed by the game rules.

Section 4: Game-Specific Requirements

• License Plate/Team Number: Ensure the team number is clearly visible on at least two opposing sides of the robot using the official VEX license plate kit.
• Field Elements: Verify that the robot does not contain any devices designed to intentionally damage or interact unsafely with field elements.
• Autonomous Coding: Confirm that the robot's autonomous code is loaded and ready for initial verification.

Pro Tips & Pitfalls

• Pro Tip: Create a "Go-Bag" for inspection containing a set of Allen wrenches, extra zip ties, a spare battery, and a printed copy of the current VRC Game Manual.
• Pro Tip: Perform a "shake test." Turn the robot off and gently shake it; if parts fall off or rattle significantly, reinforce those areas before heading to the inspection station.
• Pitfall: Waiting until the last minute. Inspection lines are longest during the first two hours of the event. Go as soon as the pits open.
• Pitfall: Ignoring "legal parts" definitions. Don't assume a part is legal just because it looks like a VEX part; always check the Appendix of the Game Manual.

Frequently Asked Questions

Q: What happens if my robot fails the initial inspection? A: You will be given a "Fix-It" list by the inspector. You must return to your pit, address the non-compliance issues, and return to the inspection station for a re-inspection before you are permitted to compete.

Q: Can I use VEX IQ parts on a VEX V5 robot? A: Generally, no. VEX V5 and VEX IQ are separate ecosystems. Only parts specifically listed as "VRC Legal" in the current Game Manual appendices are permitted.

Q: Do I need to bring my robot to inspection fully charged? A: Yes. It is standard practice to have your primary and backup batteries fully charged to verify that the robot operates correctly under full power conditions.
