# Research Queue — Fabric Growth

## Active Queue

### Deep Dive Hardware (minimum: LED codes + fault reference + setup + CAN config)
- [ ] SPARK Flex (REV-11-2159) — LED codes, fault reference, getting started
- [ ] CANcoder (CTR Electronics) — LED codes, fault reference, setup, CAN config
- [ ] roboRIO — LED codes, fault codes, setup, configuration
- [ ] PDH (REV Power Distribution Hub) — LED codes, fault reference, wiring guide

### Device Specs (RPM, amps, torque, load)
- [ ] NEO Vortex — full specs + comparison data
- [ ] Kraken X60 — full specs + comparison data
- [ ] Falcon 500 — full specs + comparison data
- [ ] SPARK Flex — current/thermal specs
- [ ] CANcoder — electrical specs, current draw

### Competition Analysis (Limelight vs PhotonVision, Vortex vs Kraken)
- [ ] Competition file: Limelight vs PhotonVision — feature comparison, pricing, ease of use, student learning curve
- [ ] Competition file: Kraken X60 vs NEO Vortex — specs, pricing, availability, integration with MK4i
- [ ] Competition file: CTRE vs REV ecosystem — motor controllers, sensors, CAN busses

### Firmware/Software Update Channels (→ programming channel)
- [ ] REV Hardware Client — SPARK Flex, SPARK MAX, NEO Vortex firmware updates
- [ ] CTR Phoenix Tuner X — CANcoder, Talon FX, Pigeon 2.0, CAN bus diagnostics
- [ ] PhotonVision — Raspberry Pi image updates, AprilTag pipeline updates
- [ ] YAGSL — Java library updates, swerve control improvements
- [ ] WPILib — annual robot framework updates
- [ ] Phoenix Pro — CTR license tier, advanced features

**Routing:** Firmware/software updates surface via Oracle push → MrC reviews → routes to 2890-bot → posts to `#programming` channel. Students shouldn't miss critical updates.

## Research Log

### 2026-05-04 — Initial setup
Keywords files created for all three silos. Growth system designed. Queue initialized with items triggered by current wiki content.

### 2026-05-04 PM — First research pass
Completed 5 of 6 queued items. Added hardware deep dive requirements (LED codes + fault reference as minimum baseline). Added competition comparison files for Limelight/PhotonVision and Kraken/Vortex.

### 2026-05-04 PM — Expanded scope
- Hardware minimum baseline: LED codes + fault reference + setup + CAN config (for all core robot hardware)
- Device specs: RPM, amps, torque, load for all motors and controllers
- Competition files: Limelight vs PhotonVision, Kraken vs Vortex, CTRE vs REV ecosystem
