Progress of a modular prosthetic arm
1 Upper limb prostheses-design restraints Active prosthetic devices to replace missing hands or arms have much in common with robotic dextrous manipulators for industrial tasks (Gruver, 1994). However, the design of an upper limb prosthesis presents a set of restraints which may differ considerably from those in other robotics applications. A mass-produced robot of standardised design may be us...
متن کاملAn LPV Approach to Sensor Fault Diagnosis of Robotic Arm
One of the major challenges in robotic arms is to diagnosis sensor fault. To address this challenge, this paper presents an LPV approach. Initially, the dynamics of a two-link manipulator is modelled with a polytopic linear parameter varying structure and then by using a descriptor system approach and a robust design of a suitable unknown input observer by means of pole placement method along w...
متن کاملA Novel Arm-Wrestling Robot Using Motion Dependant Force Control
In recent decades, aging population of most advanced countries has increased sharply, and elderly health care has become economically a big social issue. One way to cope with this problem is to introduce various service robots such as an arm-wrestling robot proposed in the article into our daily lives, which are able to promote elderly health and to save elderly welfare cost. For successful exe...
متن کاملA modular six-directional force sensor for prosthetic assessment: a technical note.
A device designed to measure the forces and moments transmitted through prostheses of persons with lower limb amputation is presented. The sensing unit design is an advancement over previous prosthesis force measurement devices in that it is very thin (19 mm) and lightweight (527.5 g, including signal-conditioning instrumentation). The disk-shaped transducer fits between the socket and socket a...
متن کاملModeling and analysis of a three-component piezoelectric force sensor
This paper presents a mathematical model for the vibration analysis of a three-component piezoelectric force sensor. The cubic theory of weakly nonlinear electroelasticity is applied to the model for describing the electromechanical coupling effect in the piezoelectric sensing elements which operate in thickness-shear and thickness-stretch vibration modes. Hamilton's principle is used to derive...
