    This technology represents an important and significant advance in mine detection. It perhaps could lead to a change in direction to our defenses against terrorists.

    I understand this can be accomplished with a $50 radar module… is this true?

    Yes, GPR is a mature technology and therefore the equipment is relatively inexpensive, particularly in comparison to alternative technologies. This is a major advantage of this design for humanitarian demining since many countries that are affected by landmine presence cannot afford expensive solutions.

    Important topic thanks for sharing. You said this works for a landmind buried at 10cm depth, is that pretty common? How effective is that robot able of tiptoeing though the land mine field? (or does it not have to get too close/ cheap enough that it’s ok if it goes boom?) What if the robot gets stuck like that Mars rover on rock years ago, do the undergrad. assistants get sent in? All in all great project I hope it helps make the world safer.

    Thank you for your interest and checking out my work! This has been a very fun and interesting project and I have been lucky to work on it since the very beginning.
    10cm is a typical depth for anti-personnel landmines. At this depth they are concealed from sight, but shallow enough to be triggered. We have also looked at 5cm and 15cm with the same success.
    Our plan with the robot is to have it walk a designated route. It can “see” landmines before fully approaching them, but we probably will not incorporate this knowledge into the walking path, since+ we don’t believe the robot will exert enough pressure to trigger the landmines. If the robot does get stuck (such as the Mars rover), then there would probably be deminers nearby to assist.
