Although personal robots hold great promise, they face many barriers to being accepted and adopted in our homes [1]–[3]. As these robots are expected to perform personal tasks, their burden of trustworthiness is far greater than that of service or industrial robots. Several studies have explored our acceptance of robots, studying factors such as natural interaction via speech [4], gaze [5], and appearance [4], expectation setting via apologizing [6], and predictability of behavior [1].
