Eliminations are where defense decides matches, and where a mistimed contact turns a great play into a match-losing foul. This lesson covers both sides: how to defend effectively and legally, and how to keep scoring when you're the one being defended.
Effective legal defense. The goal is to deny the opponent's keystone robot enough scoring to drop them below a threshold or out of a win — without breaking rules. The constraints (verify the exact wording and values in the 2026 REBUILT Game Manual Section 7, Game Rules, and the latest Team Updates, every event):
- Don't over-pin. You may use contact to slow and redirect an opponent, but in 2026 REBUILT you cannot continuously PIN them for more than 3 seconds, after which you must back off and give them room. Count it in your head and release.
- Don't tip or entangle. Deliberately tipping, attaching to, or entangling an opponent is illegal and draws major penalties.
- Stay out of their frame. Reaching components inside an opponent's bumper opening is a foul.
Fouls are expensive — a MINOR FOUL gives the opponent 5 points and a MAJOR FOUL gives them 15, and in REBUILT exceeding the pin limit is a MINOR FOUL that escalates to a MAJOR FOUL for every additional 3 seconds uncorrected. In a close elim match those points are the whole game. The disciplined defender denies points by positioning and timing — getting in the lane between the opponent and the HUB, forcing long paths, and disrupting their rhythm — not by mauling them.
Driver technique for defense. Use slow/precision mode for fine positioning, keep your bumpers between the opponent and their target, and play the angles: forcing a robot to take the long way around the field denies cycles without any contact at all. A great defender often barely touches the opponent — they just make every cycle slower.
Surviving incoming defense. When you're the keystone and they put a defender on you:
- Don't fight; reroute. Use field-relative drive and your strafe to take a different lane to the HUB rather than shoving back (shoving invites fouls from both sides and stalls you).
- Have a fallback role. This is why a redundant IAS matters — if you're shut down farming, switch to the job they're not defending (assist a climb, score during a different active-HUB window).
- Bait and exploit the pin limit. If a defender over-commits to pinning, the clock works for you: once they hit the 3-second pin limit they must release, and a quick driver punishes that release window with a fast cycle.
- Draw nothing, give nothing. Never retaliate; a frustration foul on you is exactly what aggressive defense is trying to provoke.
The meta-point: elimination defense is a duel of discipline. The team that knows the rules to the letter, counts its own pin clock, and has a rehearsed fallback when defended will out-execute a more athletic but undisciplined opponent. Drill both roles on the practice field so neither is improvised on Saturday.
Key takeaways
- Legal defense denies points by positioning, lane control, and timing - not by pinning over 3 seconds, tipping, entangling, or reaching into frames.
- A MINOR FOUL gives the opponent 5 pts and a MAJOR FOUL 15 pts; count your own 3-second pin clock and never retaliate when defended.
- Survive incoming defense by rerouting with field-relative strafe, switching to a fallback role, and punishing the release after an over-committed pin.
Lesson quiz
RequiredAnswer all 3 questions correctly to complete this lesson.
1.Why is defense often a more viable strategy in eliminations than in qualification matches?
2.FRC pinning rules limit how long a robot may trap an opponent against a field element before it must give them room. What is the design intent of this limit?
3.What is a key way to 'survive' as the targeted robot when an opponent commits hard defense in eliminations?
