  1. 1. Model-based design of haptic devices

    Författare :Ahmad Aftab; Kjell Andersson; Ulf Sellgren; Per Wennhage; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Haptic device; model-based design; stiffness; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : Efficient engineering design and development of high precision and reliable surgical simulators, like haptic devices for surgical training benefits from model-based and simulation driven design. The complexity of the design space, multi-domains, multicriteria requirements and multi-physics character of the behavior of such a product ask for a model based systematic approach for creating and validating compact and computationally efficient simulation models to be used for the design process.

  2. 2. A methodology for situated and effective design of haptic devices

    Författare :Xuan Sun; Kjell Andersson; Ulf Sellgren; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Design optimization; haptic devices; metamodel; multi-criteria; situatedness; Machine Design; Maskinkonstruktion;

    Sammanfattning : The realism of virtual surgery through a surgical simulator depends largely on the precision and reliability of the haptic device. The quality of perception depends on the design of the haptic device, which presents a complex design task due to the multi-criteria and conflicting character of the functional and performance requirements.

  3. 3. Design and optimization of parallel haptic devices : Design methodology and experimental evaluation

    Författare :Suleman Khan; Kjell Andersson; Jan Wikander; Ölvander Johan; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Medical simulation; 6-DOF haptic devices; design methodology.; SRA - ICT; SRA - Informations- och kommunikationsteknik;

    Sammanfattning : The simulation of surgical procedures, in the case of hard tissues such as bone or teeth milling, using a haptic milling surgery simulator requires a haptic device which can provide high stiffness and transparency. To mimic a real milling process of hard tissue, such as for example creating a narrow channel or cavity, the simulator needs to provide force/torque feedback in 5–6 degrees of freedom (DOF). LÄS MER

  4. 4. Effective development of haptic devices using a model-based and simulation-driven design approach

    Författare :Aftab Ahmad; Kjell Andersson; Damien Chablat; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Haptic device; model-based design; design optimization;

    Sammanfattning : Virtual reality (VR)-based surgical simulators using haptic devices can increase the effectiveness of surgical training for surgeons when performing surgical procedures in hard tissues such as bones or teeth milling. The realism of virtual surgery through a surgical simulator depends largely on the precision and reliability of the haptic device, which reflects the interaction with the virtual model. LÄS MER

  5. 5. Haptic Navigation Aids for the Visually Impaired

    Författare :Daniel Innala Ahlmark; Luleå tekniska universitet; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industrial Electronics; Industriell elektronik;

    Sammanfattning : Assistive technologies have improved the situation in society for visually impaired individuals.The rapid development the last decades have made both work and education much more accessible. Despite this, moving about independently is still a major challenge, one that at worst can lead to isolation and a decreased quality of life. LÄS MER
