—The imitation between different types of robots
remains an unsolved task for a long time. The assignment of
the correct angles to each joint is critical for robot motion.
However, different robots have different structures, thus this
discrepancy causes a difficulty when converting a motion to
another type of robot. For solving this problem, we propose a
GA-based method that can find the conversion matrix needed
to map joint angles of one robot to another. There are two
objectives to consider when creating an imitation; reducing the
difference between the ideal imitation and the converted
imitation and keeping the stability. Three experiments were
conducted; a stable experiment, an unstable experiment and a
double learning experiment. As a result, the double experiment
showed a high concordance rate of 93.5%, the highest stability
and the fastest speed of all experiments. These results show
great promise for the proposed method as a way to realize
motion imitation between different types of robots.
