Totally different from conventional rigid robot, bioinspired soft robot has characteristics of deformable body, flexibility, continuous changeability and high active adaptability. It has become a new evolution in robotics. In this context, a flexible pneumatic robotic actuator FPA was proposed to act as both driver and executor for soft robot configration. The structure, principle and mathematic model...
A new cable-driven soft endoscopic system is designed for cardiac ablation in a minimally invasive manner in this paper. The system is totally made of soft materials and has no rigid structures inside. In order to perform operation in the limited pericardium, a modified behavior-based control method inspired from animals is applied in this system. Experiments are performed to demonstrate the concept...
China is launching the lunar exploration mission, namely "Chang'e" project. In the third phase of the project, a probe will be sent to the moon to acquire the lunar regolith through automated drilling device. The drilling sample is expected to be sealed into a storing container which will be brought back to the earth by return capsule. Drilling sample should be pulled out from the drill...
Pumps capable of transporting high-viscosity fluids and solid-liquid mixtures are essential for emergency situations. Today, those pumps that can transport high-viscosity fluids and solid-liquid mixtures centralize pressure at one point and convey a fluid, the size of those pumps also becomes large to put high pressure, and the point that we can set is limited. We have previously developed a peristaltic...
This paper describes the development of an endoscopic device that veers out a latex tube with jamming by granular materials. Colorectal cancer can be cured completely if it is discovered and treated early with a large intestine endoscope. A conventional endoscope can screen and heal the inside of the intestine, but such surgery is difficult for doctors, and it can take 300 or more training sessions...
Non-invasive colonoscopy is an important procedure to find the malignant tumor of large intestine in its early stage. Micro mimetic robot shows a potential advantage to perform the examination because of its small volume and autonomous locomotion principle. This research presented a prototype of micro robotic colonoscope based on inchworm-like motion method. The prototype has 16 mm diameter, 90 mm...
Endotracheal Intubation (ETI) is a common airway procedure used to connect the larynx and the lungs through the windpipe of patients under emergency situations. The process is carried out by a laryngoscope inserted into the mouth, and helps doctors in viewing the glottis and inserting the tube. In 2012, we developed a humanoid robot for ETI training, called WKA-5R, which was able to simulate various...
In this paper, we discuss a signal transmission function of an artificial circulatory system. We proposed a biomimetic circulatory system so as to imitate the homeostatic function of the human circulation system [1]. The following blood functions were imitated in the system: (1) clotting, (2) energy supply, and (3) motor cooling. However, the circulatory system has other functions, for example, signal...
Drill sampling has been widely employed in extraterrestrial exploration. Since the extraterrestrial environment is uncertain and different from that on the earth, the extraterrestrial drill sampling mission is at risk of failure. Therefore, the principle of drilling and coring in extraterrestrial environment and the structural parameters of special drilling tools should be tested and verified. In...
