Status: Living document (v2025-11-08). Purpose: Define and prioritize electronic wheelchair models targeted for adapter / interface support (input devices, sensing, telemetry) based on US market popularity and connector accessibility.
This document catalogs high-impact electric wheelchair models sold in (or frequently imported to) the United States from 2022–2025 and assigns support priority tiers for a universal adapter / integration kit. It emphasizes:
- Controller interface availability (analog proportional, digital bus, CAN / RS485, proprietary multi-drop).
- Connector physical form factors (DB9, 4-pin DCI, 3-pin / 4-pin XLR, LiNX DX bus module, proprietary battery port, USB-C).
- Market share concentration to maximize addressable users with minimal hardware SKUs.
- Technical feasibility (signal accessibility without firmware reverse engineering, safety isolation).
| Tier | Target Coverage Goal | Criteria | Typical Tasks |
|---|---|---|---|
| Tier 1 (Immediate) | ~55–65% of active US users | High-volume consumer & travel models; rehab platforms with open/known joystick analog input (R-Net DB9, VR2/Pilot+ 4-pin, Shark DCI) | Adapter harnesses, input mapping, basic telemetry (speed, battery %). |
| Tier 2 (Near-Term) | +20–25% incremental | Mid / heavy-duty & emerging digital bus (LiNX DX, Q-Logic 3, NE Series) where documentation or reverse-engineering path is moderate | Bus sniffing tools, protocol abstraction layer, configuration utilities. |
| Tier 3 (Backlog / Specialized) | Remaining niche (<15%) | Proprietary or low-volume, advanced seating integration (standing, vertical lift, pediatric), or encrypted buses | Research partnerships, OEM NDAs, safety validation. |
| Interface | Controller Family | Tier | Notes |
|---|---|---|---|
| DB9 (R-Net analog proportional) | PG Drives R-Net (legacy analog input sidecar) | 1 | Provides joystick X/Y, mode, enable lines. Widely used on Permobil & Sunrise Quickie (premium rehab). |
| 4-pin DCI (Dynamic Shark) | Dynamic Controls Shark / DX | 1 | Common on Merits, Shoprider, budget imports. Straightforward voltage & hall sense lines. |
| 4-pin VR2/Pilot+ | PG Drives VR2 / Pilot+ / VSI | 1 | Pride & Golden mid-tier; simple analog axis and switch matrix. |
| LiNX DX Bus (4-pin micro) | Dynamic Controls LiNX | 2 | Digital (CAN-like) bus; requires protocol sniffing; used by Invacare TDX SP2, Aviva RX, Golden LiteRider Envy (variants), Drive Titan AXS. |
| Q-Logic 3 / NE Series harness | Quantum Rehab (Q-Logic), PG Drives NE | 2 | Digital CAN/RS485 hybrid; supports specialty controls. Need abstraction layer. |
| Proprietary battery-side ports (WHILL, Robooter) | WHILL Intelligent, Robooter App-enabled | 2 | Integration via external accessory rather than joystick inline (safety). |
| High-current bariatric (VR2 120A / MK6i) | PG VR2 variants, Dynamic MK5/MK6i | 2 | Same signaling as standard VR2 + seat elevation interface. |
| Specialty pediatric / standing (Permobil F5 VS, Karman standing) | R-Net extended seat modules | 3 | Requires multi-module coordination; safety-critical. |
Coverage projection: Implementing Tier 1 harnesses yields adapter readiness for ~60–65% of targeted user base; Tier 2 expands to ~85%; Tier 3 completes long tail.
Legend: P=Planned (tier assigned), S=Supported (implemented in code/hardware), R=Research. Popularity Rank: Derived from aggregated 2024–2025 reseller listings, insurance/DME claims, and online review volume (indicative, not absolute).

(Models removed from active Tier 1 consideration: very low US volume, discontinued, or highly proprietary encryption without OEM cooperation.)
- Tier 1 models: 24 listings (~60–65% of reachable US active user base).
- Tier 2 cumulative: +14 models (coverage ~85%).
- Tier 3 residual: Standing/pediatric/legacy (~15%).
- Connector SKUs required for Tier 1: 5 (DB9 R-Net, 4-pin VR2/Pilot+, 4-pin DCI Shark, VSI variant, Generic XLR inline stub). Tier 2 adds 3 (LiNX DX bus tap, Q-Logic bus, Proprietary battery dock adapter).
| Phase | Timeline (Est.) | Deliverables | Notes |
|---|---|---|---|
| Alpha (A1) | Q4 2025 | Tier 1 harness prototypes; analog joystick pass-through board; safety cutoff test rig | Focus on Pride VR2 + R-Net DB9. |
| Beta (B1) | Q1 2026 | Add LiNX DX bus sniffer, Shark DCI stable harness, firmware v0.9 (axis smoothing) | Collect CAN/differential bus traces. |
| Beta (B2) | Q2 2026 | Q-Logic 3/NE integration layer; BLE accessory bridging (Robooter/WHILL API) | Abstract digital vs analog input stack. |
| Release (R1) | Q3 2026 | Production harness set (Tier 1+2), documentation portal, regulatory pre-check | IEC 60601 isolation audit. |
| Extended (X) | 2026+ | Standing & pediatric modules (F5 VS, K450 MX), seat actuator telemetry | Dependent on OEM cooperation. |
- Unified Input Abstraction: Map analog (voltage/hall) and digital bus commands into a normalized axis + button + mode event schema.
- Safety Envelope: Enforce max delta rate (dX/dt) and emergency neutral injection if bus error detected.
- Telemetry Channels (Phase B1+): Battery SOC (via bus or voltage curve), speed estimate (encoder or inferred from current), seating position (R-Net seat module frames), error codes.
- BLE/API Bridges (Robooter, WHILL): Non-driving control surfaces (lock/unlock, horn, light toggles) while preserving OEM safety envelope.
| Risk | Impact | Mitigation |
|---|---|---|
| Bus protocol changes (firmware updates) | Adapter instability | Version fingerprinting; fallback to analog joystick overlay. |
| Seat module interference (R-Net, standing chairs) | Safety hazard | Transparent pass-through; non-invasive signal read only until validated. |
| Battery BMS proprietary data | Limited SOC accuracy | Voltage↔SOC estimation curves; optional user calibration cycle. |
| Regulatory compliance (FDA, IEC 60601) | Deployment delay | Early isolation design (optocouplers, galvanic DC/DC), maintain design history file. |
| User modification / hacking | Liability | Firmware signing; tamper-evident seals on harness. |
- 2025-11-08: Major restructure; added prioritization tiers; expanded model list (Quantum Edge, Permobil F5 VS, Quickie Q-series, etc.); defined roadmap and risk matrix.
- Confirm initial harness pinouts (VR2, Shark DCI, R-Net DB9) with bench oscilloscope capture.
- Acquire sample LiNX REM400 joystick for bus analysis (non-invasive).
- Draft electrical isolation schematic (rev A) including ESD & reverse polarity protection.
- Populate GitHub issues for each Phase Alpha deliverable.
