New webinar – Prof. Hongsoo Choi, Electromagnetically controllable tethered and untethered micro/nanorobots for robotic Interventions and cell therapy

Speaker:

Prof. Hongsoo Choi

Professor at the Department of Robotics and Mechatronics Engineering, Daegu-Gyeongbuk Institute of Science and Technology (DGIST), Korea

Abstract:

Robotic magnetic systems offer potential advantages in interventional procedures, such as precise and rapid control of magnetically steerable interventional tools (e.g., guidewires and catheters) in tortuous vessels. Recently, a robotic magnetic intervention system was developed that enables remote manipulation and active control of guidewires for the treatment of neurocardiovascular diseases. The robotic magnetic intervention system consists of a microrobotic guidewire with a soft magnetic steerable robot (MSR) attached to the tip, a human-scale electromagnetic control system, a biplane X-ray imaging unit, and a master-slave system. The flexible magnetic MSR at the tip of the guidewire uses magnetic torque to actively guide the guidewire during magnetic actuation. The microrobotic guidewire can be teleoperated forward and retracted by the master-slave system. The robotic magnetic intervention system could open new avenues in several areas of vascular interventions. At the end of the presentation, some untethered micro and nanorobots will also be introduced to demonstrate the precise delivery of multiple cells to achieve specific goals in vitro, ex vivo, and in vivo applications, including cell delivery, selective neurite alignment, neuronal connections, cancer treatment, etc. A machine learning approach is also presented to control the position of a magnetic microrobot via gradient fields generated by electromagnetic coils.

New webinar - Prof. Cédric Clévy, Pushing the limits of accuracy with tethered microrobotics: From assembling of hybrid nanophotonic circuits to characterizing of single plant fibers

Speaker:

Prof. Cédric Clévy

Professor at Universite de Franche Comte

Abstract:

In this talk, I will first present our recent research progresses on studying original robotic measurement principles and strategies to enable accurately controlled tasks to be carried out for the characterization, manipulation and assembly of microscale (i.e. sub-mm size) objects. The proposed methods especially include hybrid force-position control and open up new horizons for the human operator, as they provide suited tools enabling locally touching or deforming matter in a controlled and versatile way, well beyond his/her own dexterity limits. Positioning accuracy as small as few nanometers along multi-Degree-of-Freedom can be obtained which opens new avenues for many application fields such as for the assembly of hybrid nanophotonic circuits or for the characterization of microscale objects such as plant fibers for bio-based composites. The second part of the talk will introduce novel processes enabling the development of sub-millimeter size tethered robots, i.e. robots that embed their actuation, to achieve robotic tasks still with accuracy but in ultra-confined spaces such as in-situ microscopes or for biomedical applications.

Abstract:

The Multi-Scale Robotics & Automation Lab (MSRAL) at Purdue University performs cutting-edge research on robotic and automation systems at various length scales: macro-scale (cm to m), meso-scale (~100's of um to a few mm's), micro-scale (10's of um to 100's of um), and nano-scale (nm).   All of the developed systems are designed to interact with the environment in unique ways.  In this talk, I will discuss some recent MSRAL microrobotics projects on developing learned models for 2D micromanipulation tasks, different types of families of wireless mobile microrobots driven by external magnetic fields that we have developed over the years.  These include the micro-scale tumbling microrobot (µTUM), magnetically aligned nanorods in alginate capsules microrobots (MANiACs), the micro-force sensing mobile microrobot (µFSMM), work on controlling teams of mobile microrobots, microscale Dual Locomotion Mode Multi-Functional Robots (μDMMFs), and Helical Adaptive Multi-material MicroRobots (HAMMRs) for advanced functionality.

New webinar - Prof. Tiantian Xu, Independent and cooperative control of multiple magnetic soft-film microrobots

Speaker:

Prof. Tiantian Xu

Associate Professor, Shenzhen Institutes of Advanced Technology, Chinese Academy of Sciences

Abstract:

Untethered, wirelessly controlled microrobots have a broad application prospects for the bioengineering due to their small scales. Multiple small-scale robots enable cooperation and increase the operating efficiency. However, independent control of multiple magnetic small-scale robots is a great challenge, because the robots receive identical control inputs from the same external magnetic field. We propose a novel strategy of completely decoupled independent control of magnetically actuated flexible swimming millirobots. The strategy is verified by experiments of independent position control of up to four millirobots and independent path following control of up to three millirobots with small errors. Then, we propose an adaptive leader-follower formation control of two magnetically actuated millirobots with heterogeneous magnetization and achieved an autonomous navigation in confined environments.
