Abstract-Managing user expectations of personal robots becomes particularly challenging when the end-user just wants to know what the robot can do, and neither understands nor cares about its technical specifications. In describing what a robot can do to such an end-user, we explored the questions of (a) whether or not such users would respond to expectation setting about personal robots and, if so, (b) how such expectation setting would influence human-robot interactions and people's perceptions of the robots. Using a 2 (expectation setting: high vs. low) x 2 (robot type: Pleo vs. AIBO) between-participants experiment (N=24), we examined these questions. We found that people's initial beliefs about the robot's capabilities are indeed influenced by expectation setting tactics. Contrary to the hypotheses predicted by the Self-Fulfilling Prophecy and Confirmation Bias, we found that erring on the side of setting expectations lower rather than higher led to less disappointment and more positive appraisals of the robot's competence.
A novel 12.7kV Sic SICGT (Sic Commutated Gate turn-off Thyristor) was developed for on-line uses in power utility applications, which has the highest blocking voltage among the reported semiconductor switching devices.Its leakage current is low and is less than 1 x A/cm2 at 9 kV and at 250°C . Its on-state voltage at 100 A/cmz is 6.6 V and is lower than that of a 9 kV Si GTO, which is composed of two 4.5 kV GTOs connected in series. Its turn-on time and turn-off time are 0 . 2 2 '~~ and 2.68 ps respectively, which are about 1/50 and 1/10 of a commercialized 6 kV 6 kA Si-GTO. PWh4 half bridge inverter composed of SICGTs demonstrated output voltage of fl.25 kV and output power of 0.8 kVA respectively, which are the highest values among the reported SIC half bridge inverters.
5'-nucleotidase, an adenosine producing enzyme with a glycosylphosphatidylinositol-anchored structure, was localized in human ejaculated spermatozoa. The poly-L-lysine-coated dish method was used to prepare the specimens, and the cerium method was employed for electron-microscopic enzyme localization. Precipitates indicating enzyme activity were detected on the outer side of the external plasma membrane of the acrosomal region. This enzyme may play a role in sperm motility and male infertility.
Human-Robot Interaction researchers are beginning to reach out to fields not traditionally associated with interaction research, such as the performing arts, cartooning, and animation. These collaborations offer the potential for novel insights about how to get robots and people to interact more effectively, but they also involve a number of unique challenges. This full-day workshop will offer a venue for HRI researchers and their collaborators from these diverse fields to report on their work, share insights about the collaboration process, and to help begin to define an exciting new area in HRI.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
