Development of a Test Method for Assisted Walking Trolleys
Yoichi Asano,Hiroyuki Jinbo,Naoya Watanabe 제어로봇시스템학회 2019 제어로봇시스템학회 국제학술대회 논문집 Vol.2019 No.10
Manufacturers have recently been developing assistive walking devices with electric motors, based on rollators and walking trolleys, in Japan. These assistive devices have electric motors to assist walking on sloped surfaces. Furthermore, they have a function that automatically suppresses the speed on downhill slopes. Here a walking experiment was conducted to investigate the speed at which the suppression function needed to be applied in various walking conditions. The subjects in the experiment walked while leaning on the assistive device, applying forces of 37 (horizontal) and 204 N (vertical) on downhill slopes. Furthermore, an analysis of the walking data obtained from traditional walking trolleys revealed that 80% of the subjects walked at a speed of 2.5 km/h or more. Two experiments were conducted to develop a test method that analyzed the performance of the suppression function on downhill slopes. The proposed test method results yielded sufficient accuracy.

Development of a Test Method for Walking Trolleys with an Assist Function
Koji Matsumoto,Yoichi Asano,Hiroyuki Jinbo 제어로봇시스템학회 2019 제어로봇시스템학회 국제학술대회 논문집 Vol.2019 No.10
Walking trolleys that are currently being manufactured have a function that prevents downslope movement when the user crosses a slope. In this study, we have developed a test method to evaluate this function. First, we measured the handle-operating force exerted by elderly persons when crossing a slope by carrying out an experiment with 17 elderly participants. Analysis of the results indicated that the handle-operating force was 28 N. Based on these results, we developed a test method and a test equipment. Furthermore, we used the test equipment to conduct experiments on walking trolleys with and without activating the assist function to validate the test method. It was found that the proposed test can be performed with sufficient accuracy.
