Development of a control algorithm for the ultrasound scanning robot (NCCUSR) using ultrasound image and force feedback.
The international journal of medical robotics + computer assisted surgery : MRCAS
Jun 8, 2016
BACKGROUND: Clinicians who frequently perform ultrasound scanning procedures often suffer from musculoskeletal disorders, arthritis, and myalgias. To minimize their occurrence and to assist clinicians, ultrasound scanning robots have been developed w...
Effect of actuating cell source on locomotion of organic living machines with electrocompacted collagen skeleton.
Bioinspiration & biomimetics
May 9, 2016
In robotics, there is a need for small scale, compliant actuators for use in medical applications or minimally invasive environmental monitoring. Biohybrid devices offer one solution to this need by using muscle cells to actuate compliant scaffolds. ...
Bi-directional series-parallel elastic actuator and overlap of the actuation layers.
Bioinspiration & biomimetics
Jan 27, 2016
Several robotics applications require high torque-to-weight ratio and energy efficient actuators. Progress in that direction was made by introducing compliant elements into the actuation. A large variety of actuators were developed such as series ela...
A scalable, high resolution strain sensing matrix suitable for tactile transduction.
Journal of biomechanics
Dec 8, 2015
The integration of tactile information, such as contact area, displacement magnitude, velocity, and acceleration, is paramount to the optimization of robotics in human-centric environments. Cost effective embeddable sensors with scalable receptive fi...
Distributed flow sensing for closed-loop speed control of a flexible fish robot.
Bioinspiration & biomimetics
Oct 23, 2015
Flexibility plays an important role in fish behavior by enabling high maneuverability for predator avoidance and swimming in turbulent flow. This paper presents a novel flexible fish robot equipped with distributed pressure sensors for flow sensing. ...
Using Wearable Sensors and Machine Learning Models to Separate Functional Upper Extremity Use From Walking-Associated Arm Movements.
Archives of physical medicine and rehabilitation
Oct 3, 2015
OBJECTIVE: To improve measurement of upper extremity (UE) use in the community by evaluating the feasibility of using body-worn sensor data and machine learning models to distinguish productive prehensile and bimanual UE activity use from extraneous ...
Piezoresistive Tactile Sensor Discriminating Multidirectional Forces.
Sensors (Basel, Switzerland)
Oct 2, 2015
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...
The Effects of Fluidic Loading on Underwater Contact Sensing with Robotic Fins and Beams.
IEEE transactions on haptics
Oct 1, 2015
As robots become more involved in underwater operations, understanding underwater contact sensing with compliant systems is fundamental to engineering useful haptic interfaces and vehicles. Despite knowledge of contact sensation in air, little is kno...
A biomimetic underwater vehicle actuated by waves with ionic polymer-metal composite soft sensors.
Bioinspiration & biomimetics
Sep 28, 2015
The ionic polymer-metal composite (IPMC) is a soft material based actuator and sensor and has a promising potential in underwater application. This paper describes a hybrid biomimetic underwater vehicle that uses IPMCs as sensors. Propelled by the en...
Texture recognition and localization in amorphous robotic skin.
Bioinspiration & biomimetics
Sep 9, 2015
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...
