Reporters obtained the following quote from the background information supplied by the inventors: “Gimbals have been utilized in robots to actuate pitch and yaw of appendages, such as cameras, heads, and the like. However, gimbal motors can be heavy. For example, gimbals can frequently weigh more than 40 grams, which m ay not be desirable for smaller or lighter robot designs. Gimbals can also requi re placement directly at the location of movement (e.g. at the pivot point of th e head, camera, etc.), which can place the entire mass of the heavy gimbal on th e longest lever of a robot. This can result in the robot being unbalanced and su sceptible to toppling. Further, gimbals can require a large amount of empty spac e within a robot housing or shell in order to have ample room to actuate multipl e axes. Accommodating such a large amount of empty space can require significant materials for the robot housing and/or can prevent utilization of a gimbal with in the constraints of a smaller robot design.”
