Abstract
The technology for autonomous driving is developing rapidly. One application of autonomous driving is the Autonomous Delivery Robots (ADR). The ADR has gained a lot of attention in both the academia and industry. However, most of the extant studies about the ADR focus on the technical side. There is a lack of research on the users' perspective about this new technology. This study applies topic modeling and sentiment analyses to summarize the comments in Weibo about the ADR. The results show that there are both positive and negative sentiments regarding the ADR. The contribution of this study is that the results can help researchers understand the users' concerns about ADR. The negative sentiments can provide guidance to the ADR developers to improve the design of the robots and to allay the users' concerns.
