Operational Paradigm

Built for Saudi topographyfrom Empty Quarter dunes to Sarawat ridgelinesTHAR projects autonomous capability into zones where wheeled and tracked platforms fail.

By leveraging a biomimetic quadrupedal architecture, THAR delivers dynamic balancing, omnidirectional mobility, and terrain adaptation that conventional UGVs cannot match. The mission is clear: maximize precision while removing soldiers from the highest-risk edge of the fight.

Length 1.2 m
Width 0.8 m
Base Mass ~50 kg
Payload 20 kg

Core mission: When the task is extreme, machines absorb the risk. THAR operates as a frontline shield for reconnaissance, logistics, and force protection.

Chapter 02

Chassis & Materials

Structural integrity is engineered for kinetic shock, high-frequency vibration, and abrasive dust while preserving a low mass profile for endurance and payload margin.

2.1 Material Composition

The primary endoskeleton is CNC-machined from Aerospace-Grade Aluminum Alloy (7075-T6) for strength-to-weight and fatigue resistance. Exterior ballistic and dust-shielding panels use Carbon Fiber Reinforced Polymers (CFRP) with Kevlar weaves over vital-component zones.

Engineering Projections

Orthographic views support payload integration, maintenance access planning, and rapid manufacturing readiness. Symmetry and modular hardpoints are intentional design constraints.

Sensor Fusion & AI

Zero-visibility operationssandstorms, night, GPS-denied zonesrequire redundant multi-modal perception and onboard inference with no cloud dependency for critical survival loops.

4.1 Sensor Head

  • 3D LiDAR solid-state mapping & SLAM
  • Thermal FLIR Boson heat signatures
  • RGB-D HDR stereo for close obstacle work
  • Sapphire lenses against sand abrasion

4.2 Edge Compute

NVIDIA Jetson Orin NX (up to 100 TOPS) on hardened Linux + ROS 2. Waypoint navigation, obstacle avoidance, and real-time threat classification run locally.
