Smart joints

ROBO-SMART for expansion joints


Structural monitoring


  • Value-added option for joints – turns normal joint into "smart" one with pre-fitted sensors

  • Provides data relating to joint and bridge

  • Helps optimise life-cycle costs

  • Compatible with ROBO-CONTROL Structural Health Monitoring


The ROBO-SMART for expansion joints is a small, self-powered and integrated acquisition unit. The precise and durable sensors with robust electronics transfer the measured data via 3G GSM network to a mageba server for 24-hour online data presentation and access via secure web interface. The ROBO-SMART sensors for expansion joints can be assembled directly in factory or as an upgrade on site.


Any type of expansion joint from mageba’s wide range can be designed and manufactured with an integrated structural health monitoring system.

The use of a ROBO-SMART monitoring system can enable the life-cycle cost optimisation of an expansion joint by measuring accumulated movements leading to reduced maintenance intervals. Using such a system, the structure’s behaviour can be assessed on the basis of continuously measured parameters, with real-time data accessible online at any time and receiving warnings in case of passing of certain thresholds (e.g. movements, vibrations, rotations). Moreover, future expansion joint replacement projects will benefit from continuous measurement of maximum movements, leading to optimised design of the new expansion joints based on actual required rotational and movement capacities.
