A Study on Autonomous Stair-climbing System Using Landing Gear for Stair-climbing Robot

Abstract: In this paper, we propose the Autonomous Stair-climbing system based on data from ToF sensors and IMU in developing stair-climbing robots to passive wheelchair users. Autonomous stair-climbing system are controlled by separating the timing of landing gear operation by location and utilizing state machines. To prove the theory, we construct and experiment with standard model stairs. Through an experiment to get the Attack angle, the average error of operating landing gear was 2.19% and the average error of the Attack angle was 2.78%, and the step division and status transition of the autonomous stair-climbing system were verified. As a result, the performance of the proposed techniques will reduce constraints of transportation handicapped.

Balance stair-climbing wheelchair and stair-climbing method thereof

Abstract: The invention relates to the field of electrically-powered wheelchairs, and particularly discloses a balance stair-climbing wheelchair and a stair-climbing method thereof. The technical problems thatin the prior art, stair-climbing wheelchairs move unstably, have large impact and are expensive are mainly solved. The balance stair-climbing wheelchair is characterized by comprising a mechanical system, a track transmission module, an auxiliary wheel, a control sensor system and a whole machine skeleton mechanism, wherein the mechanical system comprises a chassis arranged on two sides of the balance stair-climbing wheelchair; the track transmission module is symmetrically installed on two sides of the chassis; the auxiliary wheel is arranged at the rear end of the balance stair-climbing wheelchair; the control sensor system is arranged in the mechanical system, and controls movement of the mechanical system in cooperation; and the whole machine skeleton mechanism is arranged above the mechanical system. A wheel-track compound scheme is adopted, the advantages of a wheel mechanism and a track mechanism are fully combined, when the balance stair-climbing wheelchair is used on a flat surface, the track transmission module is put away, the balance stair-climbing wheelchair can run like an ordinary electrically-powered wheelchair, and when the balance stair-climbing wheelchair encounters stairs or barriers, the track transmission module can be put down, so that the balance stair-climbing wheelchair conducts stair-climbing motion or passes over the barriers.

Is High-intensity Stair Climbing An Effective Alternative To Traditional Cardiac Rehabilitation Exercise?: 1646 Board #240 May 28 10:30 AM - 12:00 PM

Abstract: BACKGROUND: Virtual cycling classes offer riders a unique exercise experience through cycling feedback of cadence, resistance and total work output on multi-touch counsels; however, despite popularity, little is known regarding physiological and perceptual responses when cycling with performance feedback in comparison to a typical Spin bike which lacks feedback. PURPOSE: This study compared intensity selection and perceptual responses between receiving cycling feedback vs. no feedback when completing a virtual Spin class. METHODS: Individuals (N = 14) of varying aerobic fitness (VO2 max 41.0 ± 8.0 ml/kg/min) completed a VO2 max trial and two cycling sessions. Each session, completed on a Peloton bike, consisted of a preselected 30-minute Spin class; one session was completed with cycling feedback (VIS) of cadence, resistance, and total work output, and the other with no feedback (NOF). Following each bout, session RPE (SRPE) was estimated and a Physical Activity Enjoyment Scale (PACES) was completed. Paired t-tests were used to compare cadence, resistance, and total work of the warm-up, workout, and cool-down of each session. Perceptual measures of SRPE and PACES were also compared between sessions using paired t-test. RESULTS: Warm-up cadence was significantly higher (p < 0.01) for VIS (93.3 ± 6.7) vs. NOF (85.3 ± 12.3); whereas, cool-down resistance was significantly lower (p < 0.01) for VIS (30.2 ± 3.4) vs. NOF (36.0 ± 6.0) with no significant differences for workout portion. Perceptual measures were not significantly different, except for accomplishment approaching significance (p = 0.09) with a greater response for VIS vs. NOF. Lastly, the majority (93%) of participants preferred VIS over NOF. CONCLUSION: Results suggest cycling feedback could assist exercisers in achieving instructor suggested intensity during warm-up and cool-down. Additionally, with greater preference and sense of accomplishment with cycling feedback there is the potential to increase exercise adherence.
