Mechanical actuators driven by water that respond to multiple stimuli, exhibit fast responses and large deformations, and generate high stress have potential in artificial muscles, motors, and generators. Meeting all these requirements in a single device remains a challenge. We report a graphene monolayer paper that undergoes reversible deformation. Its graphene oxide cells wrinkle and extend i...

Two direct methods for the diagnosis of trichinellosis were compared: trichinoscopy and artificial digestion. Muscles from 17 wistar rats, orally infected with 500 Trichinella spiralis encysted larvae were examined. From each of the following muscles: diaphragm, tongue, masseters, intercostals, triceps brachialis and cuadriceps femoralis, 648,440 larvae from 1 g samples were recovered. The line...

In this paper, experimental study of robust control for robot manipulator actuated by pneumatic artificial muscles was realized. The experimented controller belonged to the class of variable structure systems which is called nonsingular terminal sliding mode (NTSM). The control approach is based on the time delay estimation method. First, the nonsingular terminal sliding mode control approach w...

The modeling of pneumatic actuators, also known as artificial muscles, has been the main focus in several research papers in the past [1, 2, 3, 4, 5]. At the Center for Intelligent Systems (CIS) at Vanderbilt University, we have been using pneumatic actuators for our Intelligent Soft Arm Control (ISAC, Figure 1). For the position control of a joint, driven by two artificial muscles, a physical ...

This dissertation reports on the developments of the bipedal walking robot Lucy. Special about it is that the biped is not actuated with the classical electrical drives but with pleated pneumatic artificial muscles. In an antagonistic setup of such muscles both the torque and the compliance are controllable. From human walking there is evidence that compliance plays an important role in energy ...

Abstract Recent advances in bionics have made it possible to create various tissue and organs. Using this cell culture technology, engineers developed a robot driven by three-dimensional cultured muscle cells (bioactuator)—a robot. For more applications, researchers been tissues organs with bio3D printer. However, printed printer not used for yet. The aim of our study is develop easy fabricatio...
