A study of the postures and locomotor modes of Alouatta palliata was conducted from mid-June to mid-September 1974 on Barro Colorado Island, Panama Canal Zone. Activities, postures, and locomotor modes were recorded relative to the position of the animals in the trees and to the size and angulatiry of the support structures. Most activities, in particular(More)
Variability in motor rehabilitation program outcomes can be attributed not only to individual components (human patient/rehabilitation equipment) but also to their system-level interactions. Thus, effective deployment of a rehabilitation program depends upon: 1) suitable therapist selection of user-device ergonomics; 2) adjustable device settings; and 3)(More)
Parallel-architecture haptic devices offer significant advantages over serial-architecture counterparts in applications requiring high stiffness and high accuracy. To this end, many haptic devices have been created and deployed by modularly piecing together several serial-chain arms to form an in-parallel system. However, the overall system performance(More)
Needle biopsy is an important and common procedure for lesion detection or tissue extraction within the human body. Physicians conducting such procedures rely primarily on the sense of “touch” (kinesthetic feedback from needle) to estimate the current needle position and organs within its vicinity. This skill takes time to acquire and mature, often by(More)
INTRODUCTION Tissue biopsies, the procurement of small tissue samples, remain the gold standard for assessing the health of internal organs such as kidney, liver, and bone. Extracted tissues are used to find abnormal cells (e.g. cancers), investigate symptoms (e.g. ulcers, hepatitis, kidney disease or endometriosis), or inflammation [1]. The anatomical(More)
As an interdisciplinary field lying at the intersection of biology and robotics, bio-inspired robotics has seen considerable interest from a research, education, and ultimately application perspective. The scope of this interest has ranged from creating and operating walking, crawling, and flying robots based on biological counterparts; to evaluating(More)
There is considerable scientific and commercial interest in understanding the mechanics of mastication. In this paper, the authors develop quantitative engineering tools to enable this process by: (i) designing a general purpose mastication simulator test-bed based on parallel architecture manipulator, capable of producing the requisite motions and forces;(More)
