Virtual Reality-Based Framework for Service Robotics: Data monitoring and recording during rehabilitation scenarios

Nowadays, robotics systems offer many opportunities to assist humans in their daily lives. Unfortunately, the additional freedom, required to autonomously operate in different environments, comes with an increased risk during operation. In this paper, we introduce our data recorder system to provide transparency of past events during human-robot interactions. The general concept of our system is based on a modular design that allows rapid prototyping for the fast evolution of service robotic systems. Furthermore, our virtual reality interface and data observations make the system one of a kind and enable complete user immersion in past interaction events. Our system was applied to a rehabilitation scenario to demonstrate its feasibility, performance, and capabilities. In a real-world example, we showed the necessity and practicality of such a system. By presenting our concept, we advanced one major step toward human-robot symbiosis.
