Designing a microhydraulically-driven mini-robotic squid
… positions the actuator for applications in microrobotics, which includes systems on the centimeter-scale and below. In this thesis, I present the design of a miniature robotic "squid" which features the MEA as the driving component. The system was inspired by cephalopod paralarvae, which …

Force control and collision avoidance strategies for kinematically redundant manipulators
… space, underwater, hazardous environments, and microrobotics, brought new challenges for robotic researchers. Position control strategies failed in performing tasks that needed interaction with a robot's environment. On the other hand, non-redundant manipulators were unable to perform tasks that …

Analysis and Modeling of Magnetized Microswimmers: Effects of Geometry and Magnetic Properties
In recent years, much effort has been placed on development of microscale devices capable of propulsion in fluidic environments. These devices have numerous possible applications in biomedicine, microfabrication and sensing. One type of these devices that has drawn much attention among researchers …

Atomic layer deposition for mechanical, magnetic, and robotic systems
The Japanese paper arts origami and kirigami have revolutionized design of three-dimensional structures, metamaterials, and robots from planar materials. The design principles in these art forms are especially valuable for small systems because most nanofabrication involves lithographic patterning …

Bacteria-Enabled Autonomous Drug Delivery Systems: Development, Characterization of Intratumoral Transport and Modeling
Systemic chemotherapy is a major therapeutic approach for nearly all types and stages of cancer. Success of this treatment depends not only on the efficacy of the therapeutics but also on the transport of the drug to all tumor cells in sufficient concentrations. Intratumoral drug transport is …

Bacteria-Enabled Autonomous Drug Delivery Systems: Design, Modeling, and Characterization of Transport and Sensing
The lack of efficacy of existing chemotherapeutic treatments of solid tumors is partially attributed to the limited diffusion distance of therapeutics and the low selectivity of anti-cancer drugs with respect to cancerous tissue, which also leads to high levels of systemic toxicity in patients. …

Smart Polymer Electromechanical Actuators for Soft Microrobotic Applications
Ionic electroactive polymer (IEAP) actuators are a class of electroactive polymer devices that exhibit electromechanical coupling through ion transport in the device. They consist of an ionomeric membrane coated with conductive network composites (CNCs) and conductive electrodes on both sides. A …

Automation of Single Cell Micromanipulation and Microsurgery for Blastocyst Embryo Biopsy
Abstract: The recent growing interest in single cell biology demonstrates that micromanipulation and microsurgical advance strategies are required to carry out single cell surgical processes, such as the Preimplantation Genetic Diagnosis (PGD). To perform PGD, a sample from the inner material of …
