DESCRIPTION (provided by applicant): Specific Aims: Motion Control Inc. proposes to develop a rugged, electric-powered work-hand/gripper for electric arm prostheses. This new terminal device (TD) will be lighter in weight, can be used in more extreme environments, and will offer more versatile gripping shapes than existing electric TDs. Motion Control is perfectly positioned to build upon the recent development of the Motion Control (MC) Hand, which includes a 2-speed drive producing 25 lb. of pinch force, and the highly functional Flexion Wrist. Background: The modern electric arm prosthesis has significant advantages over body-powered devices: freedom from uncomfortable control cables (also allowing greater work envelope), very high pinch force (requiring little effort), and more natural appearance. However, existing electric work TDs are not durable enough for many work environments. The effort: During Phase I, Motion Control will design and build engineering models of two versions of the proposed Work-Hand. One will integrate hand-like shapes molded in rugged plastic, used without a protective hand shell. The second version will implement hook-type TD fingers, for a very lightweight and versatile alternative. Water-resistant housings for the drive will be developed for both versions of the TD, which will be interchangeable with nearly all electric hands currently in use.

描述（由申请人提供）： 具体目标：Motion Control Inc. 提议开发一种用于电动假肢的坚固耐用的电动工作手/夹具。这种新型终端设备 (TD) 的重量将更轻，可在更极端的环境中使用，并且比现有的电动 TD 提供更通用的抓握形状。运动控制完美地建立在最新开发的运动控制 (MC) 手的基础上，其中包括可产生 25 磅夹紧力的 2 速驱动器和功能强大的屈曲手腕。 背景：与身体驱动的设备相比，现代电动手臂假肢具有显着的优势：没有不舒适的控制电缆（也允许更大的工作范围）、非常高的捏力（需要很少的力）以及更自然的外观。然而，现有的电动工作 TD 对于许多工作环境而言不够耐用。 工作：在第一阶段，运动控制将设计和构建两个版本的拟议 Work-Hand 的工程模型。其中一种将集成由坚固的塑料模制而成的类似手的形状，在没有保护性手壳的情况下使用。第二个版本将采用钩式 TD 手指，作为一种非常轻便且多功能的替代方案。两个版本的 TD 都将开发驱动器的防水外壳，该外壳可与目前使用的几乎所有电动手互换。
