Tether: The Lifeline of IM3™ Technology

We received some great questions about our IM3™ technology in a recent webinar, and we look forward to answering them over the coming weeks. In this week’s blog, we address whether there is a method for recovering a robotic inspection crawler from a buried pipeline if it stops.


While the concept of wireless robots seems convenient like a cordless phone, one of the direct benefits of a tethered system is the extraction of the system in the unlikely event of a malfunction by tether cable. All Eddyfi Technologies’ Inuktun tether cables have a Kevlar strength braid built into the construction as a safety measure. Check out this article, “Tight Leash, Long Lead – The Benefits of a Tethered Robot”.

It may look like your standard power cord, but the tether that connects your power system to your operational unit, whether an inspection camera or robotic crawler, is literally the lifeline for your IM3™ technology. We offer a few tips for maximum tether life and reliability here.

Eddyfi Technologies’ Inuktun robotic crawlers and inspection cameras are designed and built to perform remote visual inspection and nondestructive testing in the most inhospitable environments.
