Comparing speed to complete progressively more difficult mobile robot paths between human tele‐operators and humans with sensor‐systems to assist
Abstract
Purpose
The purpose of this paper is to investigate the effect on time to complete a task depending on how a human operator interacts with a mobile‐robot. Interaction is investigated using two tele‐operated mobile‐robot systems, three different ways of interacting with robots and several different environments. The speed of a tele‐operator in completing progressively more complicated driving tasks is investigated also.
Design/methodology/approach
Tele‐operators are timed completing a series of tasks using a joystick to control a mobile‐robot. They either watch the robot while operating it, or sit at a computer and view scenes remotely on a screen. Cameras are either mounted on the robot, or so that they view both the environment and robot. Tele‐operators complete tests both with and without sensors. One robot system uses an umbilical cable and one uses a radio link.
Findings
In simple environments, a tele‐operator may perform better without a sensor system to assist them but in more complicated environments then a tele‐operator may perform better with a sensor system to assist. Tele‐operators may also tend to perform better with a radio link than with an umbilical connection. Tele‐operators sometimes perform better with a camera mounted on the robot compared with pre‐mounted cameras observing the environment (but that depends on tasks being performed).
Research limitations/implications
Tele‐operated systems rely heavily on visual feedback and experienced operators. This paper investigates how to make tasks easier.
Practical implications
The paper suggests that the amount of sensor support should be varied depending on circumstances.
Originality/value
Results show that human tele‐operators perform better without the assistance of a sensor systems in simple environments.
