This model originates from an autonomous rover, which was designed to deliver medicine and blood tests in a hospital. This ball and socket joint also comes with an RC Car attachment trailer

This model was one of 7 parts used in an engineering competition to carry a trailer on the backside of an RC Car. Although the competition was not won, this part endured the brute of the crashes and testing which occurred, and never once failed, despite excessive force being applied to it throughout testing, as well as simulation stress tests
