MagBOT

A New way to inspect Steel and Iron structures

MagBOT is a robotic inspection device designed to survey iron and steel structures looking for and detecting defects.
Using a novel DiWheel arrangement, MagBOT easily handles horizontal and vertical planes of the structure and even works upside down!
MagBOT uses a variety of sensors including optical and magnetic to locate and report latent flaws.

MagBOT Advantages

Automation

MagBOT is fully automated and uses a powerful DSP chip to control its movements and collect data. A wireless interface moves collected data to a laptop for storage or analysis.

Magnet Flux Leakage (MFL)

MagBOT uses Magnetic Flux Leakage (MFL) sensor as its primary detector of structural defects such as cracks. MFL is a tried and true technique to locate surface and subsurface defects on structures.

Sensors

In addition to the MFL sensor, MagBOT has an onboard camera for close inspection and an accelerometer to detect orientation. All of these sensor output are transmitted wirelessly and logged for future reference and analysis.

Mobility

MagBOT's innovative design allows it to transition on most structures from one plane to next. A clever arrangement of permanent magnets allows MagBOT to reliably traverse in any orientation... even upside down!.

What is Magnetic Flux Leakage?

Magnetic Flux Leakage is a method of detecting surface and sub=surface cracks in ferrous material such as iron and steel. It is a classic Non-Destructive Test (NDT) method that has been in use for at least 80 years. It operates by exposing a magnetic field to the item under test. If a crack occurs part of the magnetic field will 'escape' and be detected by magnetic sensor.

Normal Operation
The diagram at right shows a Magnetic Flux Leakage system in operation.
A North and South magnet create a magnetic 'circuit' including the item under test
at the bottom of the diagram. The top view show the MFL system with no defect.
The magnetic lines travel through the material and very little leakage is detected by
the sensor.
Crack Detection
On the bottom of the diagram a defect exists in the ferrous material.
Magnetic flux 'leaks' because of change in the magnetic permeability between
the ferrous material and air in the defect. The magnetic field can be detected
using a sensor. On the MagBOT, a hall effect device is used to detect anomalies and report
possible defects.
