Combining complementary expertise, three investigators in the Houston area Becka, Tsekos and Shah, embarked on a journey to develop a cyber-physical system (CPS) for deliving localized therapeutic interventions using MRI Powered & Guided Tetherless Effectors. For Tsekos and Shah, this research was motivated and inspired by their earlier works in the development of yet another CPS focused on for MR-guided intracardiac interventions.

This theme, resulted to an NSF award entitled “CPS: Synergy: Collaborative Research: MRI Powered & Guided Tetherless Effectors for Localized Therapeutic Interventions”

This award was focused on developing core technologies and integrating into a CPS that uses a magnetic resonance imaging (MRI) scanner to wirelessly power, control and guide tetherless ferrous milli-robots for accurate therapeutic interventions. This CPS integrates physical (scanner sensor/actuator, effectors, patient, operator) and cyber (world modeling, combined sensor and effector control, operator immersion). The three Investigators and their teams brought together complementary expertise:

  • Becker (ECE @UH): effector designs, swarm single-source control, magnetism

  • Tsekos (CS @UH): cyber-framework, MRI and robot-to-MRI control, human-in/on-the-loop and interfacing

  • Shah (CardioMR @Methodist-Houston): Clinical perspective and MR studies


Recognizing the niche anc challenging character of this theme, we proposed and followed a rather holistic, end-to-end, approach designing from the ground-up a novel CPS that links sensing, effector & sensor control and visual/force-feedback for comprehensive perception of the physical environment. This entailed works in

  • Sensor-based real-time modeling of physical world,

  • Sensor control

  • Effector control

  • Human-machine interfacing via hologram for immersion into information & control

  • Interventional Medicine.

In the fields of cyber-framework, robot-to-MRI control and human-in/on-the-loop and interfacing this project has resulted top a plethora of outcomes that are listed in the corresponding sections below
