INTELLIGENT WHEELCHAIR DESIGN

独立行动能力对儿童和成人的发展至关重要 功能独立。我们计划开发一种“智能轮椅”。 作为(1)行动辅助设备，提供安全和独立的 立即向用户移动和(2)提供帮助的教学工具 使用者发展操作电动轮椅所需的技能 而不需要技术干预。智能轮椅将使 使用连接到车载计算机的各种传感器来 为轮椅操作员提供导航辅助。同相 I，将开发一个原型，它接受来自标准的输入 模拟操纵杆并与用户共享对轮椅的控制 以防止与障碍物相撞。原型将是 由临床医生和潜在用户在临床过程中进行评估 审判。在第二阶段，原型将扩大以适应 多种输入法，并提供不同程度的帮助 轮椅使用者取决于使用者的需求和能力。 智能轮椅系统的拟议商业应用 两个商业应用。作为一项行动援助，它将提供 即时移动到目前无法运营的个人 电动轮椅。作为一种培训辅助工具，它将被治疗师使用 在辅助技术诊所和活跃在 轮式移动性，帮助客户安全地发展技能 需要独立操作标准电动轮椅。在 长远来说，它将为未来的发展奠定基础 智能移动辅助服务。

Independent mobility is crucial for childhood development and adult functional independence. We propose to develop a "smart wheelchair" to serve as (1) a mobility aid to provide safe and independent motion to users immediately and (2) an instructional tool to help users develop skills necessary to operate a power wheelchair without technological intervention. The smart wheelchair will make use of a variety of sensors attached to an on board computer to provide navigation assistance to the wheelchair operator. In Phase I, a prototype will be developed that accepts input from a standard analog joystick and shares control of the wheelchair with the user to prevent collisions with obstacles. The prototype will be evaluated by both clinicians and potential users during clinical trials. In Phase II, the prototype will be expanded to accommodate multiple input methods and provide varying levels of assistance to the wheelchair user depending on the user's needs and abilities. PROPOSED COMMERCIAL APPLICATIONS The Smart Wheelchair System has two commercial applications. As a mobility aid it will provide immediate mobility to individuals currently unable to operate a power wheelchair. As a training aid it will be used by therapists in assistive technology clinics and school systems active in wheeled mobility to help clients to safely develop the skills needed tn independently operate a standard power wheelchair. In the long term it will provide a foundation for future development in intelligent mobility assistance.
