Over Under Rules |
Game Introduction |
The game for this year is VEX Over Under! |
*All images in this section are from the VEX Over Under Game Manual and property of the RECF |
Goals in VEX Over Under: |
* Score triballs in goals or offensive zones. |
* Elevate your robot at the end of the match |
* Prevent the opposing alliance from scoring points. |
The primary game objects are triballs: |
* Height : 6.18” |
* Width: 6.18” |
* Weight: 110 ± 20 grams |
* Outer diameter: 7.00” |
Triballs can be scored as such: |
Triball scored in Goal |
5 points |
Triball scored in Offensive Zone |
2 points |
Next, Goals, where triballs can be scored, have the following dimensions: |
* Width: 23.08” |
* Length: 47.13” |
* Height: 5.78” |
One important implication is that the triballs are taller than the height of the goal, so the bars on the goal will have to flex upwards slightly for the triballs to go into the goal. |
Next, we have the Elevation Bars; an alliance can Elevate at the end of match on these to gain extra points: |
