A body powered prehensor with variable mechanical advantage.
The purpose of this research was to improve body powered, voluntary closing (VC) prosthetic prehension. A prototype prehensor with variable mechanical advantage was fabricated and tested. The device operates at low mechanical advantage during sizing of an object to reduce cable excursion requirements. It shifts to high mechanical advantage during gripping to allow high prehensile forces to be g...
متن کاملComparison of body-powered voluntary opening and voluntary closing prehensor for activities of daily life.
Persons with an upper-limb amputation who use a body-powered prosthesis typically control the prehensor through contralateral shoulder movement, which is transmitted through a Bowden cable. Increased cable tension either opens or closes the prehensor; when tension is released, some passive element, such as a spring, returns the prehensor to the default state (closed or open). In this study, we ...
متن کاملClosed-chain motion with large mechanical advantage
One of the constraints that severely limit the capability of highly redundant manipulator arms is the actuator torque limits. This paper presents a way to achieve large effective forces from weak actuators by exploiting large mechanical advantage that results from systems near singularities. While large mechanical advantages have been applied near singularities in many instances, this method al...
متن کاملA body-powered functional upper limb orthosis.
This paper describes the development and preliminary testing of a functional upper-limb orthosis for people that have limited strength in their arms. This is symptomatic of conditions such as muscular dystrophy (MD), spinal muscular atrophy (SMA), and partial spinal cord injury. The exoskeletal orthosis is wheelchair mounted, has two links and four degrees of freedom. It uses linear elastic ele...
متن کاملNumerical Study of Mixed Convection in a Lid-Driven Enclosure with a Centered Body Using Nanofluid Variable Properties
In the present study, mixed convection laminar flow around an adiabatic body in a Lid-driven enclosure filled with nanofluid using variable thermal conductivity and variable viscosity is numerically investigated. The fluid around the body in the enclosure is a water- based nanofluid containing Al2O3 nanoparticles. The Vertical enclosure’s walls are maintained at constant cold temperature an...
