The present paper discusses the control design of a magnetically-guided microrobotic system in blood vessels to perform minimally invasive medical procedures. Such microrobots consist of a polymer binded aggregate of nanosized ferromagnetic particles and a possible payload that can be propelled by the gradient coils of a magnetic device. A fine modeling is developed and used to define an optima...

Microrobots have a number of potential applications for micromanipulation and assembly, but also offer challenges in power and control. This paper describes an uncalibrated vision-based control system for magnetically actuated microrobots operating untethered at the interface between two immiscible fluids. The microrobots are 20 μm thick and approximately 100–200 μm in lateral dimension. Severa...

This paper describes the kinematic analysis of two different cricket locomotion modalities, and the use of these data in a dynamic simulation to combine and simplify the insect’s complex three-dimensional movements. The results of this simulation will then become the input to the design and control of a microrobot capable of mimicking the walking and jumping behaviors of the cricket.
