Changeable Grasping Force Unit for Under-Actuated Gripper with Self-adaptive Grasping
The grasping force of traditional under-actuated hands can hardly be kept during grasping. It is a crucial task to improve the grasping forces of robotic hands. Changeable grasping forces unit is one of the most effective solutions. This paper proposed a linkage changeable grasping force (CGF) unit integrated with linkage under-actuation mechanism in accordance with summary of proceeding work o...
متن کاملCantilever bending based on humidity-actuated mesoporous silica/silicon bilayers
We use a soft templating approach in combination with evaporation induced self-assembly to prepare mesoporous films containing cylindrical pores with elliptical cross-section on an ordered pore lattice. The film is deposited on silicon-based commercial atomic force microscope (AFM) cantilevers using dip coating. This bilayer cantilever is mounted in a humidity controlled AFM, and its deflection...
متن کاملA triple-jaw actuated and sensorized instrument for grasping large organs during minimally invasive robotic surgery.
BACKGROUND Secure grasping and effective manipulation of delicate large organs during robotic surgery operations needs especially designed instruments that can enclose a large amount of tissue and feed back the pinch forces. METHODS A large organ triple-jaw grasper was instrumented using practical force sensory and actuating systems. A force tracking scheme was proposed to facilitate auto-gra...
متن کاملA vacuum-actuated microtissue stretcher for long-term exposure to oscillatory strain within a 3D matrix
Although our understanding of cellular behavior in response to extracellular biological and mechanical stimuli has greatly advanced using conventional 2D cell culture methods, these techniques lack physiological relevance. We developed the microtissue vacuum-actuated stretcher (MVAS) to probe cellular behavior within a 3D multicellular environment composed of innate matrix protein, and in respo...
متن کاملGrasping Unknown Objects with Proprioception Using a Series-Elastic-Actuated Gripper
Grasping unknown objects has been an active research topic for decades. Approaches range from using various sensors to gain information about the object (e.g. vision, tactile, etc.) to building passively compliant hands that react appropriately to contact. In this paper, we focus on grasping unknown objects using proprioception (the combination of joint position and torque sensing). Our hypothe...
