To give quadriplegics independent mobility, a "smart" microprocessor-based electric wheelchair has been developed by the Palo Alto Veterans Administration Medical Center and Stanford University. Ultrasound distance-ranging technology is employed to track the user's head position in two-dimensional space. These data are then used to determine the chair's direction and speed. A working prototype vehicle using this type of motion control has been successfully demonstrated. Obstacle detection, wall-following, and cruise control modes are other implemented features of the current design.
为了让四肢瘫痪者能够独立行动，帕洛阿尔托退伍军人管理局医疗中心和斯坦福大学共同研发了一种基于微处理器的“智能”电动轮椅。该轮椅采用超声波测距技术在二维空间中追踪使用者头部的位置。然后利用这些数据来确定轮椅的方向和速度。使用这种运动控制方式的工作原型车已成功展示。障碍物检测、靠墙跟随和巡航控制模式是当前设计的其他已实现功能。
