چکیده

The existing colonoscope requires a dexterous skill of surgeon to perform the insertion in entire colon. The procedure is painful to the patient. Therefore, biomedical and robotic researchers are developing a locomotive colonoscope that can travel safely in colon In this paper, we describe a new design and concept of semi-autonomous micro robot for colonoscopy. The micro robot comprises the actuation system, bow-shaped flexible supporters to keep the space between colon wall and the actuator, camera and LED for diagnosis and steering system to pass through the acute angle in colon. We suggest two actuating methods. One is based on the reaction force, and the other is impact force. For the performance test, the preliminary experiments are carried out in rigid pipe to validate the concept.

Air-Fluidized Grains as a Model System: Self-Propelling and Jamming

This thesis examines two concepts -self-propelling and jamming -that have been employed to unify disparate non-equilibrium systems, in the context of a monolayer of grains fluidized by a temporally and spatially homogeneous upflow of air. The first experiment examines the single particle dynamics of airfluidized rods. For Brownian rods, equipartition of energy holds and rotational motion sets a...

Surfactant-assisted fabrication of 3D Prussian blue-reduced graphene oxide hydrogel as a self-propelling motor for water treatment.

Three-dimensional Prussian blue-reduced graphene oxide hydrogel was synthesized with the assistance of sodium dodecyl sulfate (SDS) through a facile hydrothermal method. The hydrogel exhibited strong mechanical properties and was successfully applied as a self-propelling motor for water treatment. During the self-propelling degradation process, SDS facilitated the rapid liberation of oxygen bub...

Halting hemorrhage with self-propelling particles and local drug delivery

Approaches to locally deliver drugs to specific regions of the body are being developed for many clinical applications, including treating hemorrhage. Increasing the concentration of therapeutic coagulants in areas where clots are forming and growing can be achieved by directing them to the injury, such as with catheters or external delivery devices, or by systemically administering therapeutic...

A Lattice-Boltzmann model for suspensions of self-propelling colloidal particles.

We present a Lattice-Boltzmann method for simulating self-propelling (active) colloidal particles in two dimensions. Active particles with symmetric and asymmetric force distribution on their surface are considered. The velocity field generated by a single active particle, changing its orientation randomly, and the different time scales involved are characterized in detail. The steady-state spe...

Remotely powered self-propelling particles and micropumps based on miniature diodes.

Microsensors and micromachines that are capable of self-propulsion through fluids could revolutionize many aspects of technology. Few principles to propel such devices and supply them with energy are known. Here, we show that various types of miniature semiconductor diodes floating in water act as self-propelling particles when powered by an external alternating electric field. The millimetre-s...
