Discovering older adults' perceptions and expectations of domestic care service robots are vital in informing the design and development of new technologies to ensure acceptability and usability. This paper identifies issues that were elicited from older adults using different methods to promote creative thinking about domestic robots at an emotional level,(More)
Variable compliance is a subject of great interest in the robotics community, particularly in the area of Human-Robot interaction. In this work, variable compliance is achieved in a novel grasping device inspired by the hydrostatic skeletons of invertebrates. This is accomplished passively, relying on material properties and innovative prototype design. The(More)
There are not enough trained colonoscopists to cope with the present recommended number of examinations required for diagnostic and surveillance purposes. If colorectal cancer screening is to be introduced, endoscopic examination of the large bowel needs to be easier to learn and significantly quicker to carry out. The ‘Bladen system’, first described in(More)
Colonoscopy tends to be more difficult to perform in women. Women also experience more pain during flexible sigmoidoscopy, and the mean insertion distance of the instrument is less than in men. The ‘Bladen system’, first described in 1993, is a non-radiological method of continuously visualising the path of the endoscope using magnetic drive coils under the(More)
A novel system for distributed force measurement between the bowel wall and the shaft of a colonoscope is presented. The system, based on the piezoresistive method, involves the integration of soft miniature transducers to a colonoscope to enable a wide range of forces to be sensed. The attached sensing sheath does not restrict the propulsion of the(More)
Joint fracture surgery quality can be improved by robotic system with high-accuracy and high-repeatability fracture fragment manipulation. A new real-time vision-based system for fragment manipulation during robot-assisted fracture surgery was developed and tested. The control strategy was accomplished by merging fast open-loop control with vision-based(More)
Our group at Bristol Robotics Laboratory has been working on a new robotic system for fracture surgery that has been previously reported [1]. The robotic system is being developed for distal femur fractures and features a robot that manipulates the small fracture fragments through small percutaneous incisions and a robot that re-aligns the long bones. The(More)
Robot-assisted orthopaedic surgery has proved to provide better outcomes over conventional surgery in terms of improved spatial accuracy and more reliable and repeatable results. We present a novel use of robots in orthopaedic surgery - precise anatomic reduction of joints' fractures. The joints of the body are frequently involved in bone breaks, typically(More)
Autonomous grasping is an important but challenging task and has therefore been intensively addressed by the robotics community. One of the important issues is the ability of the grasping device to accommodate varying object shapes in order to form a stable, multi-point grasp. Particularly in the human environment, where robots are faced with a vast set of(More)
