Space Frames with Multiple Stable Configurations [PDF]
, 2007 This paper is concerned with beamlike spaceframes that include a large number of bistable elements, and exploit the bistability of the elements to obtain structures with multiple stable configurations.

International Journal of Advanced Robotic Systems, 2018 In this article, we present an improved artificial potential field method of trajectory planning and obstacle avoidance for redundant manipulators. Specifically, we not only focused on the position for the manipulator end-effectors but also considered ...

Robot's hand and expansions in non-integer bases
, 2014 We study a robot hand model in the framework of the theory of expansions in non-integer bases. We investigate the reachable workspace and we study some configurations enjoying form closure properties.Comment: 22 pages, 10 ...

A Stiffness-Adjustable Hyperredundant Manipulator Using a Variable Neutral-Line Mechanism for Minimally Invasive Surgery [PDF]
, 2013 In robotic single-port surgery, it is desirable for a manipulator to exhibit the property of variable stiffness. Small-port incisions may require both high flexibility of the manipulator for safety purposes, as well as high structural stiffness for ...

Manipulation of a Pneumatic Hyper-Redundant Actuator
TRANSACTIONS OF THE JAPAN SOCIETY OF MECHANICAL ENGINEERS Series C, 2011 Pneumatically controlled and actuated planar snake-like device has been developed. Each joint is controlled by hardware-implemented algorithm inspired by snake's lateral undulatory locomotion. Therefore the device progresses forward whenever the lateral movement is constrained, such as a winding groove by which the tip element is guided.

Design and analysis of a robust, low-cost, highly articulated manipulator enabled by jamming of granular media [PDF]
, 2011 Hyper-redundant manipulators can be fragile, expensive, and limited in their flexibility due to the distributed and bulky actuators that are typically used to achieve the precision and degrees of freedom (DOFs) required.

An obstacle avoidance algorithm for hyper-redundant manipulators [PDF]
Proceedings., IEEE International Conference on Robotics and Automation, 2002 Novel kinematic algorithms for implementing planar hyperredundant manipulator obstacle avoidance is presented. Unlike artificial potential field methods, the method outlined is strictly geometric. Tunnels are defined in a workspace in which obstacles are presented.

An optimization approach for the inverse kinematics of a highly redundant robot [PDF]
, 2016 This paper describes a robot with 12 degrees of freedom for pick-and-place operations using bricks. In addition, an optimization approach is proposed, which determines the state of each joint (that establishes the pose for the robot) based on the ...

Nanotherapies for Atherosclerosis: Targeting, Catalysis, and Energy Transduction
Advanced Healthcare Materials, EarlyView.Atherosclerosis management is hindered by poor drug targeting and plaque heterogeneity. Nanotechnology overcomes these barriers via three core strategies: (1) target‐engineered nanocarriers that achieve lesion‐specific precision via ligand modification, biomimetic camouflage, stimuli‐responsive release, and self‐propelling nanomotors; (2) catalytic ...
