The TendonScan® Robot
For post tension tendon inspection, the robot is attached to a particular tendon. The robot then runs along the tendon using its sensors to locate faults, openings and corrosions. It also uses a system similar to a magnetic resonance imaging that is used across hospitals. This MRI like system scans the material inside the tendon itself.
The unit also transmits data wirelessly to the human inspector in a wheeled cart above. The human inspector receives and reviews the data transferred by the unit in real time. The entire process is accomplished with non-destructive testing methods to ensure the best possible results. These methods the top of the line Electric Capacitance and Magnetic Flux. Both of these work in tandem with to produce the magnetic resonance imaging like visuals.
The results speak for themselves as well. Internal structures and makeup of the tendons are revealed. This shows the human inspectors exactly where they need to repair or replace the tendons. It also identifies places where water or air might have collected in the post tension tendons.
The entire inspection requires a minimum of 3 human personnel to operate and control the unit. The unit is automated and powered by battery. As such it does not need constant supervision. The unit is attached to the post tension tendon and the post tension tendon inspection can begin.
A quantitative data report of the post tension tendon inspection is generated and is provided to the relevant authorities. The data in the report correctly highlights exactly where any discontinuations are as well as other faults.
This allows any department to correctly allocate their resources towards the particular fault. They do not have to spend their money and resources trying to fix the entire structure but only the fault at hand.
