Untethered Helical Microswimmer

Helical nanobelts have the capacity to convert rotating magnetic fields to translational motion in a low Reynolds number regime, which provides the first step toward artificial bacterial flagella for untethered swimming microrobots. More Information...

Untethered Resonant Magnetic Microrobots

One of the major challenges in building untethered sub-millimeter microrobots is delivering energy to the devices. This project explores the use of resonant magnetic bodies to harvest energy from the environment and use it for robot propulsion. More Information...

Modular Self-Assembling Robots

One possible way to enable more complex minimally invasive medical procedures, ranging from diagnosis and targeted drug delivery to complex surgical interventions, is to develop robotic systems that can self-assemble inside the body. We are currently addressing the challenge of assembly and disassembly of these devices using permanent magnetic systems. More Information...

Intraocular Visual Servoing

Future retinal therapies will be partially automated in order to increase the surgeons' ability to operate near the sensitive structure of the human eye retina. Untethered robotic devices that achieve the desired precision have been proposed, but require localization information for their control. Since the interior of the human eye is externally observable, vision can be used for localization. More Information...

Microassembly of Hybrid MEMS

In order to meet the growing interest in highly integrated hybrid MEMS devices we have been developing an advanced microassembly system that can handle subminiature objects with micron precision and vision feedback. More Information...

Fruit Fly Flight Behavior Characterization Using MEMS Force Sensors

The fruit fly (Drosophila melanogaster), shown in Figure 1, is a model organism studied by biologists for almost a century, and possesses a highly developed flight control system that provides the insect with the capability to perform robust stable flight, as well as exceedingly rapid and precise turning maneuvers.

BioMicrorobotics

BioMicrorobotics is an emerging field that combines the exciting new tools and capabilities enabled by Micro- and Nano-Technology with the established theory and techniques of robotics for biomedical applications. At IRIS we are developing sub-mm sized untethered microrobots and magnetic actuation and steering systems with a focus on ophthalmic applications. More Information...

CAD Model Based Tracking for Visually Guided Robotic Manipulation

We are using a CAD model based visual tracking approach for visually guided robotic manipulation at the micro and macro scales. In addition, we are working on methods for robust registration of CAD models in complex scenes with closely spaced model edges. More Information...

Microrobotics for Molecular Biology - Manipulating Deformable Objects at the Microscale

Intelligent Microrobotic systems have the potential to change the way in which biological cells are studied and manipulated by enabling complex biomanipulation techniques. More Information...

Integration of Micromagnetics

Magnetic actuators are capable of generating large bi-directional forces with long working lengths. They are widely used in the macro world and are of growing interest to the micro world. Many papers have been published on the use of magnetics where their unique characteristics make them the actuation method of choice in specific situations. More Information...
