This paper presents an overview of a robot
teleoperation system using voice, gesture, and humancomputer
interface (HCI) controls.
The system consists of
three basic software components including (a) acquisition
and recognition of control commands from multiple
inputs, (b) client-server network communication, and (c)
command fusion and execution by a robot and its arm.
The inputs for recognition of control commands come
from (1) wired or wireless microphones, (2) wired
orientation sensors mounted on human arms, and (3) HCI
devices, such as a mouse, a keyboard or a text file with
the sequence of control commands. The set of gesture
commands is based on the US Navy lexicon for
navigating aircrafts on the ground.
Fusion of multiple
commands is performed by (a) analyzing time delays and
(b) assigning different priorities to commands and the
clients issuing those commands. Consistent and
conflicting commands are considered before a selected
command is executed by a robot. For an emergency
control, a video signal is sent to a monitoring station.
