A robot checks concrete surfaces

Friday, 24 June 2011

Precise, self-navigating and non-destructive is the determination of concrete surfaces with the new robot platform.

Multi-storey car parks are reinforced concrete structures which exhibit complex damage patterns due to the effect of de-icing salt, continuous traffic movement and vehicle exhaust gases. Typically the assessment of potentially damaged areas can only take place in a few distinct points and using expensive destructive sampling. Therefore a non-destructive test (NDT) multi-sensor device with a high degree of automation is necessary. In the BetoScan project a self-propelled and self-navigating robot platform for NDT sensors was designed and developed. The test and evaluation system is capable of testing several hundred square metres of park deck per day with a dense measurement grid. The platform can move over obstacle-free surfaces independently according to a pre-selected path while recording spatially referenced data from selected test methods. The results of the tested surfaces can be plotted using dedicated visualisation software. The BetoScan development team has been honoured for their outstanding achievements by the German Society for Non-destructive Testing (DGZfP).
