  Trust has been shown to be a key factor in effective human-robot
collaboration. In the context of assistive robotics, the effect of trust
factors on human experience is further pronounced. Personalization of assistive
robots is an orthogonal factor positively correlated with robot adoption and
user perceptions. In this work, we investigate the relationship between these
factors through a within-subjects study (N=17). We provide different levels of
customization possibilities over baseline autonomous robot behavior and
investigate its impact on trust. Our findings indicate that increased levels of
customization was associated with higher trust and comfort perceptions. The
assistive robot design process can benefit significantly from our insights for
designing trustworthy and customized robots.
