%X Artificial muscles are formed by attaching a conducting
polymeric film to a non-conducting one. The flow of
an electric current produces a macroscopic bending movement
on the muscle. A good characterization of both, motion rate
and energy of curvature, is required for improving the efficiency
of these devices. In this paper, a two-cam stereo vision system
is proposed to acquire and process the image sequence and a
3D snake for tracking the muscle. From the curve given by
the snake, mechanical parameters of the artificial muscle can
be estimated. The movements along the life cycle of the muscle
can be compared with the energy consumed in each cycle. This
is necessary for determining the span life of these devices in
applications where they work as actuators. Results prove the
validity of this approach.
