Intake Quick Reference
Use this page as a fast comparison tool. It is not a full build guide.
Start Here
- Most FTC teams should compare
active intakeandpassive intake or clawfirst. - This page uses
passive intakefor systems sometimes informally calledinactiveintakes. - Pick the intake based on the gamepiece, cycle path, and driver alignment needs, not just what another team used.
- Reliability, jam resistance, and easy transfer into the next mechanism matter as much as pickup speed.
Active vs Passive Intake Comparison
| Comparison point | Active intake | Passive intake or claw |
|---|---|---|
| How it collects | Uses powered wheels, rollers, belts, or tubing to pull gamepieces in | Driver places or grabs a piece directly with a claw, gripper, scoop, or simple guide |
| Best at | Fast floor pickup, shorter cycles, less exact driver alignment | Precise single-piece control, awkward or large objects, simpler mechanisms |
| Tradeoffs | More moving parts, more tuning, more jam risk if packaged badly | Usually slower, needs more alignment, often handles one piece at a time |
| Build difficulty | Medium | Low |
| Driver precision needed | Low to medium | Medium to high |
| Good fit for | Games with repeated floor pickup and fast cycling | Newer teams, low-part-count robots, or games with awkward gamepieces |
| Notes | Usually the default starting point when the game rewards quick intake cycles | Often simpler to finish, but can cost cycle speed |
When an Active Intake Is Usually the Better Fit
- The game rewards fast repeated pickup from the floor.
- Your cycle time matters more than perfect control of one object at a time.
- Your team can package an intake path that moves pieces cleanly into the next mechanism.
- Your drivers need some forgiveness instead of exact claw alignment on every pickup.

When a Passive Intake or Claw Is Usually the Better Fit
- The gamepiece is large, awkward, fragile, or easy to control with a direct grab.
- Your robot only needs to pick up one piece at a time with careful placement.
- Your team needs the simplest mechanism it can finish and test early.
- Your overall design benefits more from control and simplicity than from raw cycle speed.

Common Active Intake Styles
| Style | Best at | Tradeoffs | Notes |
|---|---|---|---|
| Compliant or flap wheel intake | Fast pickup with some forgiveness for piece position | Can throw or pinch pieces if spacing and speed are wrong | Common beginner-friendly FTC pattern |
| Horizontal roller intake | Wide floor pickup and simple front intake packaging | Needs good side guides and transfer control | Often pairs well with funnels and short transfers |
| Vertical intake | Controlled lift into the robot and compact front footprint | Can be harder to package and tune cleanly | Useful when the next mechanism sits higher in the robot |
| Tubing or flexible-wheel intake | Gentle contact and adaptable geometry | Material wear and tuning can take time | Useful when soft contact helps retention |
| Intake plus transfer path | Clean handoff into a lift, bucket, or shooter path | More parts and more chances to jam | Often worth it when the robot must move pieces deeper into the robot |

Intake Path and Transfer Considerations
- A good intake is not just the front edge. The full path into the robot must stay consistent.
- Add guides, compression, and side protection so pieces do not bounce out or wedge sideways.
- Keep the transfer distance short unless there is a clear reason to move pieces farther into the robot.
- Make jam-clearing and maintenance easy between matches.
- Test intake behavior while turning, stopping, and driving into walls or field elements.
Best Practices
- Start with the simplest intake that can complete your expected game cycles.
- Prototype pickup, centering, and transfer before committing to a full robot layout.
- Match wheel, roller, or claw geometry to the actual gamepiece instead of guessing from old robots.
- Leave room to replace worn wheels, belts, tubing, or servo horns quickly.
- Tune intake speed for control and consistency, not just maximum power.
- If your intake works alone but fails when connected to the rest of the robot, fix the transfer path before adding more complexity.
Decision Flow
Use this as a quick way to narrow the options.
- Does the game reward repeated floor pickup and short cycle times?
If yes, start with an
active intake. - Is the gamepiece awkward enough that direct gripping is simpler than pulling it through rollers or wheels?
If yes, compare a
passive intake or clawfirst. - Does your robot need to control one piece very carefully before scoring?
If yes, a
passive intake or clawmay be the better fit. - Can your team package a clean path from intake to the next mechanism without constant jams? If no, simplify the intake or shorten the transfer path.
- Is your team new or short on build time? If yes, prefer the intake your team can finish early and test often.
- Can your team explain why a more complex intake helps this season more than a simpler proven one? If no, choose the simpler option.
Quick Rule of Thumb
- Pick an
active intakewhen speed, floor pickup, and forgiving alignment matter most. - Pick a
passive intake or clawwhen simplicity, direct control, or awkward gamepieces matter most. - Avoid complicated intake paths unless they clearly improve your full scoring cycle.

Confirm Before You Build
- Always confirm the current season rules, legal parts, and size constraints in the official FTC documentation.
- No intake is best for every game. Re-check your choice after you study scoring locations, gamepiece behavior, and your team capacity.
- If your intake choice makes the rest of the robot harder to finish or maintain, it is probably too complex.
