Road Disease Inspection Robot

RDI-Robot is composed of an omnidirectional mobile platform, can work flexibly with movements such as moving forward, moving backward and local steering. It can work in narrow areas. According to different application requirements, the corresponding frequency band array type GPR and a HD 3D camera are equipped. The full coverage inspection of expressway, high-grade highway, rural road, municipal road and port is realized with the high precision autonomous positioning navigation, and the comprehensive evaluation results of the apparent and internal diseases are obtained. The inspection reports are generated through in-depth learning, multi-modal data fusion and other computer-aided methods. The big data of road health is obtained perfectly.

Introduction of Typical Application Scenarios

Highway Disease Detection

The full coverage detection of the layering thickness and disease development degree before road renovation or reconstruction provides objective data for road construction design and construction cost to improve the construction, management and maintenance level of roads.

Life Cycle Quality Monitoring

Ever since the completion of roads, regular full-coverage detection will be conducted for road diseases to collect the big data of generation, expansion and deterioration of road diseases, in particular for bridge floor, settlement road section and other key sections to provide effective data support for the road design, construction and maintenance in this area.

Acceptance of New Road

The key node supervision in construction process and full coverage detection of layered thickness and hidden engineering defects in completion acceptance can timely detect construction quality problems to ensure the quality and construction period of project.

Assessment of Maintenance Effects

The maintenance effects can be objectively assessed through full coverage detection of the apparent and internal conditions of roads repair and other maintenance operations and data comparison at the same points.
