A small C-programm has been developed to simulate the walking mechanism of Jansens’s creatures. All legs in a assembly on one side have a common fixed hub. Every leg is connected via two bones to a rotating mechanism, which synchronizes and drives the movement of the legs. The program generates the locations of the joints between all “bones”, the trace of the foot and rotating driving mechanism. The output is piped into the plot program gnuplot to visualize and animate the movement.
