Comparing this approach to locomotion with that used in most other robotic snake designs illustrates the key design contribution: Most other robots of this class accomplish forward motion through a complex sequence of body movements (i.e., a gait), resulting in a forward motion that is relatively very slow, imprecise and difficult to control. The main objective of the Drexel Snake Robot was to construct a hybrid snake robot that could perform straight line motion without the need for a complex gait and with little computation.
