Magnetic particle swarms are governed by rich nonlinear collective dynamics that complicate predictive, feedback-based control in biomedical microrobotics. We develop a physics-based reduced-order ellipse model that describes the swarm morphology by its principal radii (r1, r2). At steady state, the…
This paper proposes an innovative virtual chain-based kinematic calibration for the 4PPa-2PaR parallel manipulators with subchain architectures. Conventional calibration methods for such architectures suffer from inherent limitations due to coupled parameter constraints and restricted solution space
Microscale robots introduce great perspectives into many medical applications such as drug delivery, minimally invasive surgery, and localized biometric diagnostics. Fully automatic microrobots' real-time detection and tracking using medical imagers are actually investigated for future clinical tran
Micro-scale robots introduce great prospective into many different medical applications such as targeted drug delivery, minimally invasive surgery and localized bio-metric diagnostics. This research presents a method for object detection and tracking system of a chain-like magnetic microsphere robot…
Magnetic nanoparticles (MNPs) are very attractive components in many biomedical applications, particularly as therapeutic magnetic microcarriers (TMMC) for targeted therapy. Although MNPs can be effectively gathered and transported using external magnetic fields, the optimal delivery is yet to be fu
This paper presents a novel permanent magnets based actuator capable of injecting and 2D wireless control the motion of an untethered microrobot. The actuator is obtained with a simple, but an effective arrangement of four permanent magnets. Its novelty is that it creates local maxima of the magneti…
Wireless magnetic microrobots can perform complex tasks for small-scale minimally invasive surgery (MIS) that requires high precision and dexterity. The choice of the configuration of the electromagnetic actuation (EMA) system is a key issue for reliable medical applications. This paper addresses th…
The use ofrobotic devices for drug delivery in sensitive area of the human body is an innovative and reliable solution. Most of them use magnetics fields, to steer micro-nano-robots into diseases locations. In this study, we use a magnetic actuator based on two permanent magnets as an end-effector o…
For actuating the magnetic microrobots, two types of magnetic actuation technologies have been used during the last past years. These magnetic technologies may be either electromagnetic coils or permanent magnets based systems. This second solution is not the most used by researchers, because of the…
This paper presents an optimal control strategy for navigation of multiple magnetic microbeads for future drug targeting applications. To transport the drugs, we use therapeutic magnetic microbeads as navigable agents controlled by magnetic gradients. The main difficulty is to control independently
This paper describes the propulsion of the catalytic tubular microjet using Navier-Stokes equations. Especially, the thrust capability of the microjet is outstanding compared with the other microsystems, but remains only partially understood. Studies have identified the internal precursory mechanism…
This paper presents an optimal design strategy for magnetic targeting of therapeutic drugs. In this study, to maximize the effect of the treatment and minimize adverse effects on the patient, mathematical models have been developed to find the number and the size of the boluses with respect to the g…
