我们开发了一对可安装在标准手动轮椅上的台阶攀爬装置。许多轮椅使用者希望在没有帮助的情况下独立生活。这些装置的目标使用者是那些能够独立举起轮椅前脚轮的人。这些单元安装在轮椅的靠背框架上。每个单元包括两个致动器，并具有2个自由度：伸缩运动和旋转运动。它们重量轻，不会妨碍轮椅折叠。因此，将固定有这些单元的轮椅装载到汽车中仍然相对容易。在我们早期的项目中，这些单元解决了爬一个台阶的问题。在这篇文章中，我们主要讨论一种策略，使轮椅使用者爬楼梯，包括多个步骤。我们还使用了一对便携式斜坡来完成这项任务。用户在两个台阶上覆盖30 cm高度的一对斜坡上旅行的实验结果证实了该设计的有效性。
We have developed a pair of step-climbing units that can be installed on a standard manual wheelchair. Many wheelchair users hope to lead an independent life without assistance. The target users of these units are those who can independently lift the front casters of their wheelchairs. The units are installed on the back frames of a wheelchair. Each unit comprises two actuators and has 2 degrees of freedom: telescopic motion and rotational motion. They are lightweight and do not prevent the wheelchair from being folded. Therefore, it is still relatively easy to load a wheelchair fixed with these units into a car. In our earlier project, these units addressed the problem of climbing a single step. In this article, we primarily discuss a strategy that enables wheelchair users to climb stairs comprising multiple steps. We additionally use a pair of portable slopes to achieve this task. Results of experiments where users traveled on a pair of slopes that covered a height of 30 cm over two steps confirm the effectiveness of the design.
