Next-best-view algorithms are commonly used for

covering known scenes, for example in search, maintenance,

and mapping tasks. In this paper, we consider the problem of

planning a strategy for covering articulated environments where

the robot also has to manipulate objects to inspect obstructed

areas. This problem is particularly challenging due to the many

degrees of freedom resulting from the articulation. We propose

to exploit graphics processing units present in many embedded

devices to parallelize the computations of a greedy next-best-view

approach. We implemented algorithms for costmap computation,

path planning, as well as simulation and evaluation of viewpoint

candidates in OpenGL for Embedded Systems and benchmarked

the implementations on multiple device classes ranging from

smartphones to multi-GPU servers. We introduce a heuristic for

estimating a utility map from images rendered with strategically

placed spherical cameras and show in simulation experiments

that robots can successfully explore complex articulated scenes

with our system.
