Praetorian Robotics Guide Dog Model

The PR-Guide Dog: Mobile, Multi-Modal Security Sentinel

Introduction

In dynamic environments—from sprawling campuses to critical infrastructure sites—static defenses alone can leave gaps. The PR-Guide Dog bridges that gap: a hybrid aerial-land drone designed for rapid patrol, proactive deterrence, and precisely targeted non-lethal engagement. When networked under the PR-SNN, Guide Dogs roam perimeters, broadcast warnings, and even shepherd threats into containment corridors—responding to incursions in seconds and extending security well beyond fixed emplacements.

1. System Overview

Built on a ruggedized, quad-rotor VTOL chassis with integrated all-terrain wheels, the PR-Guide Dog transitions seamlessly between flight and ground operations. Its carbon-composite roll-cage frame (IP65 rated) withstands harsh weather, while modular payload bays support a variety of deterrent and engagement modules.

Core Components

  • Flight & Drive Actuators

    • Dual ducted rotors (±15 m/s climb rate) paired with four brushless wheel-drive motors (20 km/h top speed)

  • Navigation & Control

    • Dual-GNSS with RTK correction; inertial measurement unit (IMU) for smooth transitions

    • Onboard autopilot with obstacle-aware waypoint routing

  • Payload Interface

    • Hot-swap bays for LRAD, smoke canister, spotlight, and digital comm-pod

    • Sub-munitions launcher for pepper-ball or sponge rounds

  • Communications

    • 2.4 GHz mesh radio & 5 GHz video link; optional LTE/5G uplink

    • AES-256 encryption end-to-end

2. Engagement Capabilities

Non-Lethal Options

  • Long-Range Acoustic Device (LRAD)

    • 180 m effective range; directional voice and tone patterns

  • Smoke/OC Canisters

    • Deploy at 30 m; dispersion cloud for area-denial or concealment

  • High-Intensity Spotlight

    • 8,000 lumens; remote-aimable for subject disorientation

  • Digital Comm-Pod

    • Pre-recorded or live voice: evacuation orders, warnings, crowd control messages

Sub-Lethal Options

  • Pepper-Ball Launcher

    • Firing velocity 70 m/s; area effect up to 8 m²

  • 40 mm Sponge Rounds

    • Safe-impact kinetics; effective to 40 m

  • Swarm Physical Ramming

    • Coordinated multi-Guide Dog assault for uncooperative ground targets

Key Benefits Hybrid Mobility: Aerial reach plus ground persistence—keeps eyes and deterrence on moving threats. Configurable Payloads: Mix–and–match non-lethal tools to match evolving threat profiles. Rapid Escalation: Automatic fallback from warnings to active sub-lethal engagement if ignored.

3. Multi-Modal Sensor Suite

The PR-Guide Dog’s situational awareness relies on an integrated sensor stack analogous to manned security units:

Sensor Type

Specs

Function

LiDAR Scanner

150 m range; 0.2° resolution

3D mapping for collision avoidance, perimeter scan

Thermal Camera

640×480 @ 30 Hz; 60 m range

Detect heat signatures in all lighting conditions

RGB Wide-Angle Camera

1080p @ 60 fps

Visual ID and recording for forensics

Radar Module

24 GHz FMCW; 75 m range

Coarse motion tracking in obscurants

Acoustic Sensor Array

180° mic coverage; directional gunshot detection

Instant firearm discharge alerts

Ultrasonic Proximity

5 m range; 360° coverage

Low-altitude obstacle detection

Why This Matters Seamless Day/Night Ops: Thermal and radar ensure continuous patrolling—rain or shine. False-Alarm Suppression: Fused data reduces nuisance alerts by 97 %. Integrated PR-SNN Feed: All sensor streams pipe into the Security Neural Network for centralized threat scoring and autonomous mission updates.

4. Strategic Deployment & PR-SNN Orchestration

When deployed in teams, PR-Guide Dogs amplify site security through coordinated missions:

  1. Grid-Pattern Patrols

    • Autonomous waypoint networks ensure full-site sweeps with overlapping sensor coverage.

  2. Threat Corralling

    • On detection, Guide Dogs form a mobile barrier—steering suspects toward containment zones or fixed turrets (PR-SETs).

  3. Dynamic Tasking

    • PR-SNN reallocates units in real time: from perimeter reinforcement to active-shooter interception.

  4. Operator Interaction

    • Optional human override or “one-button” approval for escalated engagement; live video/tracking feed for situational awareness.

Active-Shooter Response

Acoustic sensors pick up muzzle blasts at 120 m. Within 0.3 s, thermal imaging locates the shooter; two nearby Guide Dogs converge, broadcasting warnings via LRAD and shining spotlights. If the shooter advances, sponge rounds are delivered—neutralizing the threat before it reaches crowds.

5. Rapid Response & Mobility

Unlike static sensors, Guide Dogs can be pre-positioned or dispatched on demand:

  • Quick-Deploy Docks

    • Distributed landing pads with automated recharge and reload stations.

  • On-the-Fly Redeployment

    • PR-SNN can redirect idle drones to emerging hotspots—no human repositioning required.

  • Endurance Modes

    • Hybrid power system: Li-ion flight pack plus swappable ground-drive battery extends patrols up to 4 hours continuous.

Key Benefits First Responder Virtual Team: Acts as an always-on force multiplier ahead of human guards. Reduced Footprint: Fewer fixed cameras and patrol cars needed—cuts OPEX by up to 30 %. Adaptable Tactics: From crowd monitoring at events to perimeter sweeps at remote facilities, Guide Dogs shift roles in seconds.

6. Use Cases & Real-World Impact

Scenario

Guide Dog Role

Outcome

Perimeter Breach at Data Center

Rapid grid-patrol; detection via LiDAR; LRAD warning

Intruder deterred before reaching critical assets

Large Venue Event Security

Pre-event flyovers; crowd heat-mapping; acoustic threat alert

No-notice threats spotted 2 min before entry

Nighttime Campus Patrol

Thermal survey; sponge-round engagement of poacher

Wildlife intrusion stopped without lethal force

Emergency Evacuation Guidance

Digital comm-pod broadcasts egress routes; spotlight guidance

Evacuation time reduced by 40 %

Conclusion

The PR-Guide Dog transforms security from passive observation to active, mobile deterrence. Its hybrid aerial-land form factor, configurable non-lethal and sub-lethal payloads, and multi-modal sensing—when orchestrated by the PR-SNN—ensure threats are detected, processed, and contained within seconds. For executive decision-makers, this means scalable coverage, measurable risk reduction, and a demonstrable ROI in both safety and operational efficiency.
