This paper introduces transparency-optimized control architectures (TOCAs) using two communication channels. Two classes of two-channel TOCAs are found, thereby showing that two channels are sufficient to achieve transparency. These TOCAs achieve a greater level of transparency but poorer stability than three-channel TOCAs and four-channel TOCAs. Stability of the two-channel TOCAs has been enhanced...
This paper proposes a performance index called telepresence index for bilateral teleoperation, which can be used both for the performance evaluation of bilateral control architectures and for design purposes. This index is intended to represent a comprehensive performance objective consisting of transparency and kinematic correspondence, which are two major performance objectives of bilateral teleoperation...
In bilateral teleoperation, the performance measure has significant considerations: control objective, quantitativeness, time delay and human haptic perception, but no suitable performance measure exist. Therefore this paper investigates extended transparency as a performance measure in bilateral teleoperation. First, through an analysis based on control objective, extended transparency has two independent...
