Challenge

Client needed non-destructive evaluation of bridge deck integrity without traffic disruption. Traditional coring methods would be time-consuming and potentially weaken the structure.

Solution

• Deployed 900MHz GPR system for high-resolution scanning
• Covered 15,000 m² in 3 days during off-peak hours
• Advanced signal processing for rebar detection and delamination mapping
• 3D visualization of subsurface anomalies

Results

• Identified 12% of deck area with subsurface delamination
• Detected corrosion-induced concrete damage in critical zones
• Saved client €150,000 compared to traditional methods
• Enabled data-driven repair prioritization

Challenge

Research team needed real-time underground feature detection to prevent autonomous tractors from getting stuck in soft soil or hitting buried obstacles.

Solution

• Designed custom 2-6 GHz UWB radar system
• Integrated with existing navigation sensors (GPS, IMU, LiDAR)
• Developed real-time soil classification algorithms
• Created ROS-compatible software interface

Results

• Achieved 85% accuracy in soil type classification
• Detection range: 0.5m - 2.5m depth
• Processing latency < 100ms for real-time operation
• System now deployed in 5 research vehicles

Challenge

Electronics manufacturer needed to inspect 1200 PCBs/hour for 15 different defect types with >99% accuracy while reducing labor costs.

Solution

• Multi-camera system with specialized lighting
• Deep learning model trained on 50,000+ labeled images
• Edge AI deployment on NVIDIA Jetson platform
• Real-time defect classification and reporting dashboard

Results

• Achieved 99.3% defect detection accuracy
• Reduced false positive rate by 75% vs. manual inspection
• Inspection time: 2.8 seconds per PCB
• ROI achieved in 8 months through labor savings

Challenge

City planners needed accurate 3D maps of underground utilities (water, gas, electricity, telecom) dating back 150+ years before major infrastructure upgrade, but excavation was prohibited due to historic preservation requirements.

Solution

• Multi-frequency GPR approach (400MHz + 900MHz)
• High-density grid scanning with RTK-GPS positioning
• Advanced signal processing for pipe/cable discrimination
• 3D utility network reconstruction and CAD integration

Results

• Mapped 25 km of underground utilities across 12 city blocks
• Discovered 18 previously undocumented utility lines
• Positioning accuracy: ±10 cm horizontal, ±15 cm depth
• Prevented 3 potential utility strikes during construction phase

Challenge

Logistics company needed AGVs capable of navigating warehouse with frequent layout changes, temporary obstacles, and floor-embedded magnetic tape markers that degrade over time.

Solution

• Sensor fusion: stereo vision + GPR + LiDAR + IMU
• GPR-based magnetic tape detection (even when worn/damaged)
• Visual SLAM for dynamic obstacle avoidance
• Adaptive path planning with real-time re-routing

Results

• Navigation accuracy: ±2 cm along planned route
• Zero collisions in 6-month trial period
• Maintained operation despite 60% tape marker degradation
• Fleet of 12 AGVs now deployed, handling 800 pallets/day
