The Useworthiness of Robots for People with Physical Disabilities

Eftring, Håkan LU (1999)
Abstract (Swedish)
Popular Abstract in Swedish

Avhandlingen behandlar robotteknik och de nya möjligheter som den kan ge människor med rörelsehinder. Jag fokuserar på teknikanvändaren och teknikanvändningen, speciellt på vad som gör robothjälpmedel värda att använda. Distinktion görs mellan användvärdhet och användbarhet.



Erfarenheter från användning av den rullstolsmonterade robotarmen Manus visar att tekniska krav ställs bland annat på robotarmars acceleration, hastighet och rörelsemönster. Att enkelt kunna ställa gripdon horisontellt och vertikalt är andra krav för att snabbare och mindre koncentrationskrävande kunna utföra de vanligaste rörelserna.

Erfarenheter från användning av den rullstolsmonterade robotarmen Manus visar att tekniska krav ställs bland annat på robotarmars acceleration, hastighet och rörelsemönster. Att enkelt kunna ställa gripdon horisontellt och vertikalt är andra krav för att snabbare och mindre koncentrationskrävande kunna utföra de vanligaste rörelserna.



De första erfarenheterna av robotars användvärdhet gjordes genom tekniskt utvecklingsarbete av gripdon för bladvändning till kontorsroboten RAID. Principerna för att separera blad och bladvändningsrörelsen analyseras och beskrivs i avhandlingen. Gripdon är en central del av robotars funktionalitet och användvärdhet. Krav på en automatisk gripfunktion för förenklad robotanvändning har tagits fram genom användartester.



Avhandlingen visar på hur provanvändning av robotar som hjälpmedel kan leda till nya kunskaper om både teknikanvändningen i sig och teknikanvändarens personliga egenskaper - behov, förmågor, önskningar och drömmar.

Abstract
This thesis deals with robotics and the new possibilities it offers people with physical disabilities. I focus on the user and the use of the technology and, in particular, on what makes robotic aids worth using - useworthiness as distinguished from usability.



User experience of the wheelchair-mounted Manus manipulator shows that robotic arms must meet technical requirements in terms of acceleration, speed, and pattern of movement. Easy horizontal and vertical adjustment of the end-effector is another requirement which must be met to enable a user to carry out the most common movements faster with less concentration.



Experience of the useworthiness of robots was first obtained through the development... (More)
