Microrobotized blasting improves the bone-to-textured implant response. A preclinical in vivo biomechanical study.

Journal of the mechanical behavior of biomedical materials
This study evaluated the effect of microrobotized blasting of titanium endosteal implants relative to their manually blasted counterparts. Two different implant systems were utilized presenting two different implant surfaces. Control surfaces (Manual...

Piezoresistive Tactile Sensor Discriminating Multidirectional Forces.

Sensors (Basel, Switzerland)
Flexible tactile sensors capable of detecting the magnitude and direction of the applied force together are of great interest for application in human-interactive robots, prosthetics, and bionic arms/feet. Human skin contains excellent tactile sensin...

Effect of bladder wall thickness on miniature pneumatic artificial muscle performance.

Bioinspiration & biomimetics
Pneumatic artificial muscles (PAMs) are actuators known for their high power to weight ratio, natural compliance and light weight. Due to these advantages, PAMs have been used for orthotic devices and robotic limbs. Small scale PAMs have the same adv...

Buckling of Elastomeric Beams Enables Actuation of Soft Machines.

Advanced materials (Deerfield Beach, Fla.)
Soft, pneumatic actuators that buckle when interior pressure is less than exterior provide a new mechanism of actuation. Upon application of negative pneumatic pressure, elastic beam elements in these actuators undergo reversible, cooperative collaps...

Poroelastic Foams for Simple Fabrication of Complex Soft Robots.

Advanced materials (Deerfield Beach, Fla.)
Open-celled, elastomeric foams allow the simple design of fully 3D pneumatic soft machines using common forming techniques. This is demonstrated through the fabrication of simple actuators and an entirely soft, functional fluid pump formed in the sha...

Texture recognition and localization in amorphous robotic skin.

Bioinspiration & biomimetics
We present a soft robotic skin that can recognize and localize texture using a distributed set of sensors and computational elements that are inspired by the Pacinian corpuscle, the fast adapting, uniformly spaced mechanoreceptor with a wide receptiv...

Slithering towards autonomy: a self-contained soft robotic snake platform with integrated curvature sensing.

Bioinspiration & biomimetics
Soft robotic snakes promise significant advantages in achieving traveling curvature waves with a reduced number of active segments as well as allowing for safe and adaptive interaction with the environment and human users. However, current soft robot...

Effect of Tracheal Cuff Shape on Intracuff Pressure Change During Robot-Assisted Laparoscopic Surgery: The Tapered-Shaped Cuff Tube Versus the Cylindrical-Shaped Cuff Tube.

Journal of laparoendoscopic & advanced surgical techniques. Part A
BACKGROUND: Although the cuff of tracheal tubes can reduce airflow leakage and prevent aspiration, excessive intracuff pressure can cause tracheal mucosal injury. Robot-assisted laparoscopic surgery (RALS) can increase intracuff pressure by the Trend...

An improved quasi-steady aerodynamic model for insect wings that considers movement of the center of pressure.

Bioinspiration & biomimetics
A quasi-steady aerodynamic model in consideration of the center of pressure (C.P.) was developed for insect flight. A dynamically scaled-up robotic hawkmoth wing was used to obtain the translational lift, drag, moment and rotational force coefficient...
