摘要
记者从发明人提供的背景资料中得到以下引述：“万向架已被用于驱动诸如照相机、磁头等附件的俯仰和偏航。然而，万向架马达可能很重。例如，万向架通常重量超过40克，这对于较小或较轻的机器人设计来说可能不是理想的。万向架也可以直接在运动位置（例如，在头部、摄像机等的枢轴点）重新放置，这可以将重型万向架的整个质量放置在机器人最长的杠杆上。这会导致机器人不平衡，容易倾倒。此外，万向架可能需要机器人外壳或外壳内的大量空SPAC E，以便有足够的空间来驱动圆轴。容纳如此大量的空空间可能需要机器人外壳的大量材料和/或在较小机器人设计的限制下防止万向架的使用。
Abstract
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.”
