The layers are actually tool marks on the mold from the machining process. The parts are molded using a Shore A Urethane rubber similar to the rubber on car tires.
Our very first mold was as polished and under the correct light you can see the tool marks from the mold. Our newer molds are more polished and you can't see any tool marks. We are always trying to improve our process.

Diversity means diversity in ideas too. Some of the robots from the singapore competition might have employed strategies or ideas that we may not even have come up with in North America. - J Flex 188 [more]
