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.

he long-term vision for robotics is to have fully autonomous mobile robots that perceive the environment as humans do or even better. This article transfers the core ideas from human scene perception onto robot scene perception to contribute toward a holistic scene understanding of robots. The first contribution is to extensively survey and compare state-of-the-art robot scene perception approaches with neuroscience theories and studies of human perception. A step-by-step transfer of the perceptual process reveals similarities and differences between robots and humans. The second contribution represents an analysis of the status quo of holistic robot perception approaches to extract to what extent the perceptual capabilities of humans have been reached. Building on this, the gaps and potentials of robot perception are illustrated to address future research directions.
