Just found more on it:
Parallel link manipulators I, II
In the paper "development of an ultra high speed robot FALCON using wire
drive system" S. Kawamura et al, Ritsumeikan University, Japan describe
an ultra high speed robot based on a wire driven parallel manipulation
system. This robot can achieve vibration free high speed motion (peak
acceleration of 43 G and maximum velocity of 13 m/s with very small DC
motors (60W). The mechanism consists of seven wires (actuators). Ends of
three wires are attached to one end of a rod and the ends of other four
wires are attached to the other end of the rod, at which the robot hand
is located. The other end of each wire is attached to a pulley which is
driven by a DC servomotor. The problem of vibration resulting from use
of light weight wires is overcome by controlling the internal force in
the wires which in turn improves the structural stiffness of the system.
