Query: Cooperative Path-following Control of Remotely Operated Underwater
  Robots for Human Visual Inspection Task   Remotely operated vehicles (ROVs) have drawn much attention to underwater
tasks, such as the inspection and maintenance of infrastructure. The workload
of ROV operators tends to be high, even for the skilled ones. Therefore,
assistance methods for the operators are desired. This study focuses on a task
in which a human operator controls an underwater robot to follow a certain path
while visually inspecting objects in the vicinity of the path. In such a task,
it is desirable to realize the speed of trajectory control manually because the
visual inspection is performed by a human operator. However, to allocate
resources to visual inspection, it is desirable to minimize the workload on the
path-following by assisting with the automatic control. Therefore, the
objective of this study was to develop a cooperative path-following control
method that achieves the above-mentioned task by expanding a robust
path-following control law of nonholonomic wheeled vehicles. To simplify this
problem, we considered a path-following and visual objects recognition task in
a two-dimensional plane. We conducted an experiment with participants (n=16)
who completed the task using the proposed method and manual control. The
results showed that both the path-following errors and the workload of the
participants were significantly smaller with the proposed method than with
manual control. In addition, subjective responses demonstrated that operator
attention tended to be allocated to objects recognition rather than robot
operation tasks with the proposed method. These results indicate the
effectiveness of the proposed cooperative path-following control method.
