Senior Vice President of Product Development
- California State Polytechnic University, Pomona CA, studied math, programming, analog and digital design
- California Institute of Technology, Pasadena CA, studied advanced math, Assembly and C programming, hardware design
As Ridgetop’s Senior Vice President of Product Development, Robert Wagoner is responsible for the manufacturing and production aspects of hardware and software deliverables. He has also been leading the R&D of Ridgetop’s foundation prognostics and health management (PHM) application, Sentinel Network™, NightHawk™ NFF Reduction Software Tool, RotoSense™, the Rotary Blade Health Management System™ (RBHMS), and CPT1000™.
An experienced Software/Firmware Engineer with wide-ranging experience in the development of advanced diagnostic and prognostic products, Mr. Wagoner most recently led the development of a Fiber Bragg Grating (FBG) sensor array for monitoring worst case strain on composite material structures used on the Apache Helicopter, utilizing our existing Sentinel Wireless Gateway and Wireless IoT technologies.
In addition, he oversaw the development and commercialization of the industry acclaimed RotoSense sensor, which was most recently recognized in NASA’s Spin-Off 2017 magazine. Originating from NASA SBIR Phase 2 contract NNX11CA48C for topic A2.09, “Embedded Data Acquisition Tools for Rotorcraft Diagnostic Sensors”, this wireless rotational vibration sensor extracts high-resolution acoustic signatures from rotating components of helicopters, such as gearboxes, in harsh environments. Data from this precision instrument can be used to validate new algorithms that detect and predict faults based on external acoustic signatures, for prognostic purposes.
Mr. Wagoner led efforts on a contract with The Boeing Co. to supply advanced condition-based maintenance (CBM) technology for Boeing’s AH-64 Apache helicopter, which involved developing prognostic models for the Apache’s electrical system, to predict the remaining useful life of selected electrical components and wiring. This project demonstrated Ridgetop’s expertise and experience in developing CBM applications for rotorcraft systems, to include hardware sensors, software algorithms, graphical user interfaces (GUIs), and supporting PHM services — and ability to integrate with existing Health and Usage Monitoring Systems (HUMS) hardware. He is also technical lead and is contributing to the commercialization of Ridgetop’s wireless rotational vibration sensor, RotoSense™, as well as the SMRT™ frequency probe, and flagship product SJ BIST™.
Emphasizing his robust experience in project development, Mr. Wagoner as PI for U.S. Navy SBIR Phase II program, N022-1676, titled “Anti-Terrorism – Detection, Indications, and Warnings,” completed in Feb. 2006, addressing a net-centric multi-INT system of systems that performed a maritime demonstration that exploited the advantages of publisher/subscribers and distributed information products with dynamic retasking of sensors and sensor platforms. This was the creation of the Sentinel Network, a network health web application for the Navy that includes an IT prognostic engine on the network, and guides support personnel to resolve IT problems, platform which would evolve in to the Sentinel Suite line of products including Sentinel IoT Wireless Module, Sentinel Motion, and Sentinel PowerView.
Mr. Wagoner has developed software architecture and oversaw implementation of new methods of remotely monitoring critical assets in harsh environments. This has included design of advanced IoT-based sensors for power monitoring, strain and rotational vibration measurements (RotoSense), signal processing to detect degradation (NightHawk, CPT1000, SMRT Probe 4000), and the companion Sentinel Suite Software, the evolution of Sentinel Network, to create modular and comprehensive equipment monitoring solutions.
Mr. Wagoner has expertise in robotics development and electric propulsion design for unmanned aerial vehicles. He has developed UAV GNC/IMU-6DOF with GPS and ground station software, and created mainstream use of electric ducted fan-jet models.
Mr. Wagoner is a current member of the Institute of Electrical and Electronics Engineers (IEEE) as well as a member of the IEEE Robotics and Automation Society.
