VersaTrax™ OnSpec — Custom NDT Robotics

For Adapting to Atypical Conditions, Specific Technology Integration, and Full Custom Design of Inspection Crawlers.

VersaTrax OnSpec delivers tailored robotic solutions for inspections that standard tools can’t reach. Built on Eddyfi Technologies’ proven VersaTrax architecture and unified ICON™ control software, OnSpec combines multimission modular hardware with seamless technology integration (UT/PAUT/TOFD/TFM, ECA/TECA, ACFM®, RVI, and more) to collect the exact data you need from confined or hazardous locations—while reducing scaffolding, rope access, confined-space entry, and downtime.

Our in-house design → prototype → production teams collaborate directly with you to scope requirements, validate feasibility, and deliver a field-ready system on an agreed timeline. From compact crawlers for narrow access to deepwater variants and heavy-duty platforms with specialized tooling, OnSpec adapts to nonferrous and ferrous assets alike and integrates third-party sensors when required.


  • Approach: Bespoke configuration for asset, environment, and data objectives
  • Tech Integration: UT/PAUT/TOFD/TFM, ECA/TECA, ACFM®, RVI, and other sensing
  • Control: Unified ICON™ operator experience across VersaTrax platforms
  • Environments: Confined spaces, hazardous areas, and underwater/flooded assets
  • Data: Encoded paths, synchronized video + sensor data, reporting & exports

Welcome to a world of modular robotics designed for your remote industrial application

Industrial Robotic Applications
OnSpec Cleaning Robot

Eddyfi Technologies is an innovation leader in modular, mobile, industrial robotic systems with a global reputation for reliability, efficiency, quality, and cost effectiveness. We create technology that enables people to perform tasks that they could not otherwise do, in places they could not otherwise go. OnSpec Robotics, or custom robots built to your precise needs, enable access to areas that are too dangerous or remote for direct human intervention, providing time and cost-efficient operations.

Do you ever wish you could be in several places at once? Eddyfi Technologies has been doing it for years with our unique, multi-mission modular technology. The art and science of OnSpec Robotics is a very human endeavor taking you beyond what is humanly possible. Our remotely operated systems bridge the gap between you and the physical world, helping you reach the unreachable, see the unseen, and go safely beyond your physical limitations to perform the work left otherwise undone.

Whichever way you look, our bespoke industrial robots have your remote operation challenges covered. When the job calls for new ideas and fresh approaches, we are OnSpec. Whether it’s about integrating a unique OEM module, adapting proven technology for atypical conditions, or designing a custom solution from scratch, Eddyfi Technologies’ robotic experts will sit down with you to fully understand the exact nature of the problem, before scoping the optimal solution for your needs.

We recognize that choosing the right robotic technology for your business is a complex decision – one that goes beyond quality, reliability, and craftsmanship. We know it’s about identifying the systems best adapted for your precise needs. You require innovative solutions? It’s up to us to understand your questions and provide clear, relevant, actionable answers.

Frequently Asked Questions

How custom is “custom”?
We tailor chassis, adhesion, sensors, communications, and data workflows to your site and inspection goals.
Can you integrate thirdparty instruments?
Yes—where technically feasible and safe, we integrate external sensors/instruments alongside Eddyfi systems, with unified control and recording through ICON™.
Do OnSpec systems work underwater?
Yes—configurations are available for submerged or splashzone environments; depth and sealing are engineered to your requirement.
What’s the typical lead time?
Lead time depends on scope and validation needs; we confirm schedule during scoping once feasibility and risk are aligned.
How do you ensure data quality?
Encoded motion, synchronized visual + sensor data, and standardized reporting aligned to your procedures and codes.
