A practical example of mobile robot long term operation

N. Hawes et al., The STRANDS Project: Long-Term Autonomy in Everyday Environments, IEEE Robotics & Automation Magazine, vol. 24, no. 3, pp. 146-156, DOI: 10.1109/MRA.2016.2636359.

Thanks to the efforts of the robotics and autonomous systems community, the myriad applications and capacities of robots are ever increasing. There is increasing demand from end users for autonomous service robots that can operate in real environments for extended periods. In the Spatiotemporal Representations and Activities for Cognitive Control in Long-Term Scenarios (STRANDS) project (http://strandsproject.eu), we are tackling this demand head-on by integrating state-of-the-art artificial intelligence and robotics research into mobile service robots and deploying these systems for long-term installations in security and care environments. Our robots have been operational for a combined duration of 104 days over four deployments, autonomously performing end-user-defined tasks and traversing 116 km in the process. In this article, we describe the approach we used to enable long-term autonomous operation in everyday environments and how our robots are able to use their long run times to improve their own performance.

Interesting survey of relevant long-term applications of service robots in real environments

Roberto Pinillos, Samuel Marcos, Raul Feliz, Eduardo Zalama, Jaime Gómez-García-Bermejo, Long-term assessment of a service robot in a hotel environment, Robotics and Autonomous Systems, Volume 79, May 2016, Pages 40-57, ISSN 0921-8890, DOI: 10.1016/j.robot.2016.01.014.

The long term evaluation of the Sacarino robot is presented in this paper. The study is aimed to improve the robot‘s capabilities as a bellboy in a hotel; walking alongside the guests, providing information about the city and the hotel and providing hotel-related services. The paper establishes a three-stage assessment methodology based on the continuous measurement of a set of metrics regarding navigation and interaction with guests. Sacarino has been automatically collecting information in a real hotel environment for long periods of time. The acquired information has been analyzed and used to improve the robot’s operation in the hotel through successive refinements. Some interesting considerations and useful hints for the researchers of service robots have been extracted from the analysis of the results.
