Abstract

Autonomous mobile robots depend heavily on sensors for interpreting the external environment and planning their movement. Given the complexity of even simple environments, the use of simulation is necessary to test sensory perception and movement strategies efficiently. Accurate and efficient sensor simulation is key to the successful development and fielding of autonomous mobile robots. In this paper, we investigate the scalability of LIDAR-type sensor simulation in ROS-supported Gazebo, an open-source multi-robot simulator. Specifically, the performance and scalability of the simulator are assessed with and without support from GPU in two virtual worlds, one highly-complex in terms of the number of collision targets and one not-complex. In both cases, we increase the number of sensors and evaluate system performance. The results show that the use of GPU helps improve performance, providing better speedups in the complex scene. However, the number of sensors that can be used is limited when using GPU.

"ACM treats links as citations (references to objects) rather than as incorporations (embedding of objects). Permission is not needed to create links to citations in The ACM Digital Library or Online Guide to Computing Literature. ACM encourages the widespread distribution of links to the definitive Version of Records of its copyrighted works in the ACM Digital Library and does not require that authors obtain prior permission to include such links in their new works.

However, someone who creates a work or a service whose pattern of links substantially duplicates an ACM-copyrighted volume or issue should get prior permission from ACM. One example: the creator of "A Table of Contents for the Current Issue of TODS" -- consisting of citations and active links to author-versions of the works in the latest issue of TODS -- needs ACM permission because that creator is reproducing an ACM-copyrighted work. If all the links in the "Table of Contents" pointed to the ACM-held definitive Version of Records, ACM would normally give permission because then the new work advertises an ACM work. To avoid misunderstandings, consult with ACM before duplicating an ACM work via links.

If an author wishes to embed a copyrighted object---rather than a link---in a new work, that author needs to obtain the copyright holder's permission."
