In this paper Care-O-bot ® 3 is introduced, which is designed as a prototype for a household robot. In contrast to merely technology driven service robot developments, many considerations on embodiment were conducted. In particular, Care-O-bot ® 3 excels in its user-interaction oriented design. Nevertheless, it is equipped with leading edge technology, which is highly integrated into a very compact form. This convergence of design and technology accounts for the idea of Care-O-bot ® 3 being a product vision for a robot butler.

By taking over dull routine tasks, service robots can provide the personnel of residential care facilities with additional time for their actual care tasks. Together with the employees of an elderly care facility, possible areas to support care workers have been identified and support scenarios have been developed as part of the project WiMi-Care. On the autonomous transport vehicle CASERO and the household assistant Care-O-bot® 3, four scenarios were implemented and tested during two practical evaluations
One way to allow elderly people to stay longer in their homes is to use of service robots to support them with everyday tasks. With this goal, we design, develop and evaluate a low-cost mobile robot to communicate with elderly people. The main idea is to create an affordable communication assistant robot which is optimized for multimodal Human-Robot Interaction (HRI). Our robot can navigate autonomously through dynamic environments using a new algorithm to calculate poses for approaching persons. The robot was tested in a real life scenario in an elderly care home.
In the last decades, omnidirectional mobile robot platforms have entered many areas of industrial automation and daily life. While platforms with universal and Mecanum wheels are quite common, standard wheels have the advantage of robustness against uneven ground and slippage. This paper gives an overview on recent developments in the design of omnidirectional undercarriages with standard wheels and categorizes mechanical designs according to their holonomy. Furthermore, requirements for different applications are discussed and simple evaluation criteria are proposed that can be used to compare designs.
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.
