SENTINEL CORE
UNIVERSAL COMPUTE + POWER MODULE — THE BRAIN OF EVERY SENTINEL ROBOT

The Sentinel Core is a sealed, ruggedised IP67 aluminium enclosure housing the NVIDIA Jetson compute module, custom carrier PCB, power distribution, and SENTINEL-LINK hub. It is the only component shared across all 4 robot variants. Swapping the attached tool modules and loading the appropriate software profile converts it between Warehouse, Agriculture, Military, or Home mode. The Core is designed for field replacement in under 4 minutes using the 8-bolt lid mechanism.

SENTINEL-D ASSEMBLY PROCEDURE
1
Frame Preparation & Hinge Assembly
Inspect CFRP central plate and 4 folding arms for delamination or cracks. Install spring-loaded hinge mechanisms at each arm base with M3 titanium hardware. Verify fold/lock action — each arm must click into both deployed (180°) and stowed (0°) positions. Apply blue Loctite 242 to all structural fasteners. Torque M3 bolts to 0.9 Nm.
2
Motor & ESC Installation
Mount 4× T-Motor P80 III motors to arm tips using factory M3 adapters. Route ESC power leads through carbon arms (use silicone grommets at pass-through holes). Solder XT60 motor-to-ESC connections with 12AWG silicone wire. Mount FLAME 80A ESCs to central plate underside with thermal pads. Connect signal wires to Cube Orange+ motor outputs (M1-M4). Verify rotation direction: M1/M3 CW, M2/M4 CCW.
3
Flight Controller & Companion Computer
Mount Cube Orange+ on vibration-damped anti-vibration plate (centre of gravity). Connect GPS (UART1), telemetry (UART2), RC receiver (SBUS). Mount Jetson Orin NX 8GB on custom carrier bracket above FC, connect via USB3 for companion link. Flash ArduPilot 4.5 firmware, configure frame class = Quad-X, battery monitor on ADC. Set SERIAL2_PROTOCOL = 2 (MAVLink2) for Jetson companion link.
4
Sensor & Payload Integration
Mount Sony IMX577 3-axis gimbal to front ventral hardpoint. Co-mount FLIR Lepton 3.5 thermal on gimbal bracket (boresighted to EO camera). Install Livox Mid-360 LiDAR on dorsal centre mount, connect Ethernet to Jetson. Mount ArduSimple RTK2B GPS on rear top mast (15cm above frame for multipath rejection). Verify all sensor data streams in SENTINEL-D diagnostics.
5
Communications & Power
Install Doodle Labs RM-900 mini mesh radio on rear fuselage. Route 900 MHz antenna to tail boom (ground plane clearance). Connect to Jetson via Ethernet (SENTINEL mesh network auto-joins parent robot). Install battery tray with XT90 quick-release and balance lead breakout. Insert Tattu 6S 12Ah, verify voltage (25.2V full charge), enable battery failsafe at 21.0V (RTL) and 20.4V (land).
6
Calibration, QA Flight & Certification
Perform accelerometer + magnetometer calibration (6-axis). Calibrate ESCs (full-range PWM). Run motor spin test on bench (verify current draw <2A per motor at idle). First hover test indoors (tethered, 1m altitude, 30s). Outdoor QA flight: GPS lock, RTK fix, waypoint mission (4 points), follow-me test, RTL on low-battery simulation. Log all telemetry. Apply serial number label and QA pass sticker. Pack with foam-lined Pelican case.
DRONE COMPANION PAIRING: Each SENTINEL-D auto-pairs with its parent ground robot via Doodle Labs mesh network. The drone streams 4K + thermal video to the parent robot's Jetson for real-time AI processing (obstacle detection, target tracking, crop health analysis). Follow-me mode uses RTK GPS + visual tracking for <50cm relative position accuracy. Maximum operational radius: 10km from parent robot.

Advanced Solutions — Research Findings

01

Solid-State Batteries 2025–2027 Horizon

Solid-state batteries replace the liquid electrolyte with a solid ceramic or polymer electrolyte, eliminating dendrite formation, dramatically improving energy density, and enabling faster charging with inherent safety advantages (no thermal runaway risk).

Samsung SDI All-Solid-State
900 Wh/L volumetric density
2× current LiFePO₄ (450 Wh/L). Announced Q3 2024 for EV sector; robotics-grade cells expected Q2 2026. Samsung SDI pilot line: 200 MWh/year capacity.
QuantumScape QSE-5
380 Wh/kg gravimetric density
vs 160 Wh/kg LiFePO₄ — a 2.37× improvement. QSE-5 cells demonstrated 800+ cycles at 1C rate with <10% degradation. Anode-less architecture reduces weight further.
Projected Pricing (2027)
€120/kWh vs €90/kWh current LiFePO₄
33% cost premium for 2.4× energy density = significant net gain per kg. Price expected to reach €95/kWh by 2029 at volume (>1 GWh/year production).
SENTINEL Impact
Same weight = double autonomy
WH: 16–20 h (from 8–10 h) · AG: 28 h (from 14 h) · MK: 24 h (from 12 h) · HM: 20 h (from 10 h). Alternatively: same autonomy at 50% battery weight — critical for MK agility and HM comfort.
MEDIUM RISK Manufacturing scale-up delays possible. Mitigation: design battery bay for both LiFePO₄ and solid-state form factors. Dual-source strategy with CATL as backup supplier.
02

Solar Skin Technology Available Now

High-efficiency flexible solar cells laminated directly onto the robot's exterior shell, providing continuous trickle-charge during outdoor operation without additional weight or aerodynamic penalty.

Cell Technology
SunPower Maxeon Gen 6
24.1% efficiency, IBC (interdigitated back contact) architecture. Flexible down to 30mm radius. Conformal lamination onto curved robot surfaces using 3M VHB structural adhesive. UV-resistant ETFE encapsulant, 25-year rated lifespan.
AG Robot Integration
~0.6 m² body surface → ~90W continuous
6 panels × 0.1 m² = 0.6 m² total. At 24.1% efficiency under 1,000 W/m² (STC): 144W peak, ~90W average accounting for angle, temperature derating, and partial shading. MPPT charge controller integrated into SENTINEL Core power management.
MK Robot Integration
~0.5 m² (excluding armored areas) → ~75W
Panels mounted on non-ballistic surfaces only (top hull, rear panel, arm covers). IR-absorbing coating option for thermal signature management. Cells are shatter-resistant but not ballistic-rated — considered consumable in combat scenarios.
Annual Energy Yield (Romania)
~189 kWh/year supplemental (AG robot)
Romania average: 2,100 annual sun hours. AG 90W × 2,100h = 189 kWh/year. At €0.15/kWh grid cost, saves €28.35/year in electricity — ROI is autonomy extension, not cost savings.
Custom Integration Cost
€45/panel × 6 panels = €270 per robot
Includes Maxeon cells, ETFE laminate, 3M VHB adhesive, wiring harness with MC4 micro-connectors, and Genasun GVB-8 MPPT controller (€65). Total with controller: €335/robot.
Autonomy Impact: AG robot: +3–4 h/day extension · MK robot: +2–3 h/day extension

Deployable Solar Camouflage Panel MK / AG Models

A portable, robot-deployable solar array that doubles as camouflage concealment. The panel folds into a compact pack mounted on the robot's dorsal rail and auto-deploys via servo actuators when the robot enters a recharge cycle in the field.

Panel Dimensions
2.0 m × 1.5 m foldable = 3.0 m² deployed
Folds to 500 mm × 200 mm × 60 mm stowed package. Weight: 2.8 kg including ribs and servos. Deployment: 4-fold accordion pattern with locking hinges.
Solar Output
450W peak (SunPower Maxeon Gen 6)
3.0 m² × 24.1% efficiency × 1,000 W/m² × 0.62 (real-world derating for angle/temp/soiling) = ~450W peak realistic. Charges 48V 15Ah pack (720 Wh) in approximately 2 hours under full sun conditions.
Camouflage System
Reversible: 4 patterns on Cordura 1000D
Woodland / Desert / Snow / Urban camouflage patterns printed on Cordura 1000D ripstop nylon backing. Solar cells face skyward; camo fabric faces ground-ward when deployed as concealment shelter. DWR (durable water repellent) coating. IR signature reduced by 85% when robot is beneath deployed panel.
Structural Frame
Carbon fibre folding ribs, servo-deployed
T700 carbon fibre tubular ribs (8mm OD, 6mm ID). 4× Dynamixel XM430-W350 servos for deployment (7.3 Nm each). Auto-deploy time: 30 seconds to fully open, 20 seconds to fold and stow. Wind rating: 40 km/h sustained, 60 km/h gusts with guy-line stakes.
Unit Cost Breakdown
€1,200 total per panel assembly
Solar cells + ETFE laminate: €680 · Cordura camo fabric: €180 · CF ribs + hinges: €220 · Dynamixel servos × 4: €120. MPPT controller shared with solar skin system (already included in robot BOM).
🎯
Stealth Recharge Protocol: Robot autonomously identifies concealment position (dense vegetation, building shadow, terrain depression) using SLAM + overhead imagery analysis. Navigates to position, deploys panel, enters low-power mode during charge cycle. IR signature reduced 85% under panel. Acoustic signature: zero (no generator). Visual signature: camouflage pattern matched to terrain via onboard camera + pattern selection algorithm.

Hydrogen Fuel Cell Range Extender MK / AG Outdoor

A compact proton-exchange membrane fuel cell (PEMFC) stack that functions as a range extender, continuously charging the main battery during operation. Hydrogen is stored in lightweight field-swappable cartridges, enabling multi-day autonomous missions.

Fuel Cell Stack
Intelligent Energy 800W PEMFC
800W continuous, 1.2kW peak (30s burst). Stack weight: 2.5 kg. Operating temperature: -10°C to +45°C. Efficiency: 50% (HHV). Exhaust: pure water vapour. MTBF: 5,000 hours. Voltage output: 24–48V via integrated DC-DC converter.
Hydrogen Storage
1L cartridge @ 300 bar = 8h at 100W
Type IV carbon-composite cartridge, 300 bar (4,350 PSI). Weight: 0.8 kg per cartridge (including H₂). Quick-release bayonet connector for field swap (<15 seconds). 6 cartridges = 48 hours of 100W supplemental power. Cartridge refill from standard industrial H₂ cylinder (50L @ 200 bar) using portable booster pump.
Cost Structure
Stack: €2,800 + Cartridge system: €450
IE 800W stack: €2,800. Cartridge quick-release manifold: €180. 6× H₂ cartridges: €270 (€45 each). H₂ refill cost: ~€0.08/cartridge (industrial H₂ at €5/m³). Total system: €3,250 per robot. Annual H₂ fuel cost: ~€50 per robot at moderate use.
MK Mission Profile
72h+ endurance with 6 cartridges
MK base battery (1,440 Wh) + fuel cell at 100W continuous = 12h battery + 48h fuel cell = 60h minimum. With solar skin (+2–3h/day) and power management (sleep cycles), 72h+ total field endurance achievable. Critical for extended reconnaissance and perimeter security missions without resupply.
CONSTRAINT Not suitable for indoor models (WH, HM) — PEMFC requires air intake and produces water vapour exhaust. Hydrogen venting in enclosed spaces poses safety risk. Indoor robots rely on battery + wireless charging exclusively.
05

Wireless Charging Zones WH / HM Indoor

Resonant inductive and RF-based wireless power transfer systems that charge robots automatically without physical docking, reducing downtime and eliminating connector wear. Two technologies evaluated for different use cases.

Energous WattUp 15W
At-a-distance RF charging, FCC-approved
15W delivered power at up to 1 meter distance via focused 5.8 GHz RF beam. Robot enters charging zone, WattUp transmitter identifies receiver and delivers power directionally. No precise alignment needed — robot charges while working near transmitter zone. Efficiency: ~30% at 1m (vs 85%+ contact charging). Trade-off: convenience vs speed.
WH Warehouse Installation
Floor tiles: €120/tile × 20 tiles = €2,400
Resonant inductive floor tiles (WiTricity reference design, 200W per tile). Installed in high-traffic zones (picking aisles, staging areas, dock approach lanes). WH robot receives continuous 50–150W charge while traversing tiles. At 60% time-on-tiles, effectively provides unlimited autonomy during shift — battery never drops below 70% SOC. Installation: epoxy-sealed tiles flush with warehouse floor, IP65 rated.
HM Home Integration
Qi 15W pad near charging dock
Standard Qi 15W wireless pad at designated home location (living room corner, hallway alcove). HM navigates to pad when SOC <20%, aligns via NFC positioning, charges to 100% in ~4 hours. Slower than wired but maintenance-free — no connector wear, no alignment issues. Cost: €35 per Qi transmitter pad + €15 Qi receiver coil integrated into HM base plate.
Operational Impact: WH: effectively unlimited autonomy with floor tile system · HM: maintenance-free charging, zero connector wear

Autonomy Comparison — All Upgrade Paths

Projected autonomy figures with each technology applied independently and in combination. "Base" = current battery chemistry. Solid-state projections assume 2027 availability at same pack weight.

Robot Current Base + Solar Skin + Deploy Panel + Fuel Cell + Solid-State (2027) Maximum Combined
WH 8–10 h N/A (indoor) N/A N/A (venting) 16–20 h 20 h + wireless ∞
AG 14 h 18 h 22 h (sun) 38 h 28 h base + solar 56 h+ (all combined)
MK 12 h 15 h 20 h (sun) 72 h+ 24 h base + solar 96 h+ (all combined)
HM 10 h N/A (indoor) N/A N/A (venting) 20 h 20 h + Qi auto
📊
Recommendation: Implement solar skin (AG/MK) and wireless charging (WH/HM) immediately as low-cost, high-impact upgrades. Design battery bay for solid-state drop-in replacement (2027). Fuel cell range extender as optional premium package for MK military/security contracts requiring 72h+ endurance. Deployable solar panel as field accessory kit (sold separately or bundled with MK Pro package).

SECTION 4 UNEXPECTED COSTS & CONTINGENCY

Risk Mitigation · Supply Chain · Regulatory · Financial Buffer

Contingency budget covers foreseeable-but-uncertain costs that are typical for hardware startups entering production. Based on industry benchmarks: hardware startups typically experience 15-25% cost overruns; our 12% contingency reflects disciplined project management with some risk acceptance.

Category Estimated (EUR) Risk Assessment & Notes
Component supply chain disruptions €50,000 HIGH RISK Chip shortages (Jetson Orin NX lead time: 16–26 weeks), HEBI actuator lead times (12+ weeks, single-source), FLIR Boson thermal cores (allocation limits, US export control). Mitigation: pre-order critical components 6 months ahead, maintain safety stock of 20 units for Boson/Jetson.
Prototype iteration (3 revisions typical) €45,000 MEDIUM RISK Each Sentinel Core PCB revision costs ~€8,000 (4-layer fab + BGA components + assembly + functional test). Expect 3 revisions minimum before production-ready (rev A: bring-up, rev B: fixes, rev C: optimization). Mechanical chassis iterations: ~€3,000 each (CNC prototyping).
Regulatory delays €30,000 MEDIUM RISK CE testing failures requiring PCB redesign (EMC most common fail point), MIL-STD re-test fees (€15k per re-test for environmental qualification). ISO 13482 (HM) may require additional safety features not in initial design. Budget includes one major CE re-test cycle.
Field testing incidents €25,000 MEDIUM RISK Broken prototypes during field trials, crashed drones (expect 2–3 total losses during development), damaged laser optics (AG model, ~€2k per FLIR/Hokuyo replacement), water ingress failures. Covers repair parts and replacement components, not personnel time.
Legal (IP disputes, export compliance) €40,000 HIGH RISK ITAR consultation for MK model (US defence technology components — HEBI actuators, FLIR thermal), freedom-to-operate patent search (robotics is heavily patented), EU dual-use export control classification (EU 2021/821). May need US State Department export license for MK sales outside EU/NATO.
Software integration overruns €35,000 MEDIUM RISK ROS 2 Humble compatibility issues with custom packages, Jetson JetPack version conflicts (JetPack 6 vs CUDA 12 vs PyTorch 2.x dependency hell), real-time kernel patches, sensor driver debugging. Covers additional engineering hours and potential contractor support.
Staff recruitment & training €20,000 LOW RISK Recruiting elite Romanian engineers (job postings, recruiter fees ~15% first-year salary for key hires), onboarding period (2–4 weeks at reduced productivity), initial training on proprietary systems. Romania has strong engineering talent pool but competition with automotive sector is intense.
Currency fluctuation (EUR/USD ±5%) €15,000 LOW RISK Most electronic components priced in USD (Jetson, HEBI, FLIR, Intel RealSense). A 5% EUR/USD swing on ~€300k of USD-denominated purchases = €15k exposure. Mitigation: forward contracts with bank for large purchases, batch ordering to reduce transaction count.
CONTINGENCY SUBTOTAL €260,000 ≈ 12% of total one-time investment
