we have witnessed several teams move yellow balls from original placements from under the bars. in the past there has been variance "within an inch", but that information is not present in this year's manual. Can a ball be "cheated" this inch?
The Q&A is closed for the 2021-2022 season. Any rule changes or clarifications pertaining to the 2022 VEX Robotics World Championship will be included in the April 5 Game Manual Update. Teams attending VEX Worlds who wish to pre-submit questions for the driver's meeting should have received a contact form via email; if not, please contact your REC Foundation Team Engagement Manager for more information.
Starting placement of balls
The 1" variance can be found in rule G16:
<G16> Be prepared for minor field variance. Field tolerances may vary by as much as ±1” unless otherwise specified. Teams must design Robots accordingly.
With that being said, manually adjusting the Field to "push the limit" of this variance for strategic reasons is outside the intent of the rule. A G3-esque analogy would be for a Team to lower a Hanging Bar by 0.9" in order to make their Hanging mechanism work.
Head Referees should check Ball placement prior to the start of each Match, and re-position any that are in question into the correct starting locations.
