dc.description.abstract |
Commercial myo-electrically controlled prostheses are currently single degree of fieedom
devices with highly restrictive function. These artificial hands warrant high grip
forces due to their planar pincer movement to ensure stable prehension, thereby inherently
requiring precise and conscious effort on the part of the wearer to ensure optimum
grip.
The Southampton Hand has demonstrated the ability to devolve low-level user control
to the hand prosthesis itself by the use of the Southampton Adaptive Manipulation
Scheme. Until recently these multiple-axis prostheses have lacked clinical significance
due to poor reliability and user-oriented design.
The development of the latest device is centred on the hypothesis of enhancing stable
piehension by increasing the adaptability of the prosthesis, whilst simultaneously
minimising the necessary grip force. This is to be achieved by increasing the number
of independent degrees of freedom of the device without compromising user-effort by
utilising the Southampton hierarchical control system. Constraints such as modularity,
low weight and power consumption are factors that have been adhered to throughout
the design process.
The six independent axes of the hand are controlled by a single microprocessor. The
limiting factor in the advancement of artificial hands has frequently been the integration
of technology to the device. Consequently several accurate sensing systems were implemented
in this design to enable a more comprehensive control of the adaptable hand prosthesis.
