An amazing fully autonomous robotic worm which moves like a leech unless provoked. It is approximately two and a half feet long with metallic segmented body covered with sensitive bristles to sense its environment. Two antenna at its head are for probing for front obstacles. On sensing danger through its bristles, it speeds off to escape. Different responses are produced for different sensation received through its bristles and antenna. It was built specifically for the Robofest 5 held in Austin, Texas in April 1994.

By the way, the word "cacing" is a Malay word for "worm".
