Start Here
- Pick this style when you want a wide floor pickup and faster collection of smaller loose pieces.
- Its biggest strength is forgiving driver alignment and good cycle speed.
- Its biggest tradeoff is that it needs good guides and transfer control to avoid chaos.
- Rough build difficulty:
medium. - Rough maintenance difficulty:
medium.
Why Teams Pick This Intake
GM0 describes horizontal intakes as wider intakes rotating on a horizontal axis or plane. They are commonly used for smaller game elements and can control more than one piece at a time.
Teams usually pick this style when the game rewards repeated floor pickup, when pieces are scattered, and when a wider front opening helps drivers cycle faster.
What a Good Version Looks Like
- The front opening is wide enough to forgive slight driver error.
- Side guides center the piece before it reaches the next stage.
- The roller speed pulls pieces in without launching them out the back.
- The next mechanism sits close enough that pieces do not fall into a dead zone.
- The robot can keep collecting while slightly misaligned or while turning.

Side Guides and Centering
This style usually lives or dies on guiding. A wide roller alone is not enough.
- Add side walls, angled guides, or funnels so pieces enter the same path each time.
- Keep the guided path short.
- Test pickups that start off-center, sideways, or against a wall.
What to Watch Out For
- Wide openings can collect pieces quickly, but they can also feed pieces sideways into jams.
- If the next mechanism is too far away, pieces bounce, stall, or double-feed.
- Rollers that are too fast can throw pieces deeper than intended.
- Rollers that are too slow can stall when the robot hits a pile.
- Multi-piece pickup is helpful only if the rest of the robot can actually manage it.
Build Difficulty
Overall build complexity is usually medium.
- The front roller itself can be simple.
- The real work is in side guides, retention, and handoff packaging.
- Complexity rises fast if you add multiple stages to fix a bad initial layout.
Maintenance and Reliability
Overall maintenance complexity is usually medium.
- Inspect roller shafts, bearings, and retention hardware.
- Keep guides rigid enough that impacts do not change the intake path.
- Expect wear where pieces scrub along walls or funnels.
- Make jam-clearing easy for the drive team.
Good Starting Point
- Start with one powered front roller, basic side guides, and the shortest possible handoff.
- If the game uses smaller floor pieces and repeated cycles, this is often a practical first active intake to prototype.
- Do not add a long internal conveyor until a short direct handoff has clearly failed for packaging reasons.
Compare It to Other Intake Options
- Compared with a Compliant or Flap Wheel Intake, this style usually favors width and cycle speed over one-piece control.
- Compared with a Vertical Intake, it is usually easier to make wide and forgiving, but harder to keep tightly controlled.

What Still Needs Confirmation
- Confirm that the current season really rewards multi-piece or fast floor pickup enough to justify this style.
- Confirm that your next mechanism can accept pieces from a wide front intake without constant jams.
