This work analyses a ‘Y’ wheel configuration for stair climbing and optimizes the mechanism for a dedicated staircase configuration. This stair climbing mechanism consists of a ‘Y’ shaped wheel with a gear system which changes its mode of operation from a simple gear train to an epicyclic gear train whenever it encounters step. The analysis consists of understanding the mechanics as the ‘Y’ wheel encounters a step, why the ‘Y’ wheel tends to climb the step and how it climbs the step and starts rolling. Each case is analysed by considering governing factors like the ‘Y’ wheel link length, end wheel radius, and weight and staircase configurations, and studied to show the variation in torque requirement and reaction forces. The stair climbing mechanism is optimized using graphical method and verified using linear programing in Matlab.

Digital Human

Human stair ascent and descent are simulated in this work by using a skeletal digital human model with 55 degrees of freedom (DOFs). Hybrid predictive dynamics approach is used to predict the stair climbing motion with weapons and backpacks. In this process, the model predicts joints dynamics using optimization schemes and task-based physical constraints. The results indicated that the model can realistically match human motion and ground reaction forces data during stair climbing tasks. This can be used in human health domain such as leg prosthesis design.

Those with posttraumatic ankle osteoarthritis have a variety of sensorimotor impairments. However, no investigation has determined the effect of posttraumatic ankle osteoarthritis on stair climbing. The purpose of this study was to determine if stair ascent and descent kinetics are altered in those with posttraumatic ankle osteoarthritis. Those with posttraumatic ankle osteoarthritis had lower self-reported function than age-matched controls. Normalized peak vertical ground reaction forces during the weight acceptance phase of stair ascent and descent were also different between groups. The results suggest that those with ankle osteoarthritis have a reduced ability to control their body mass while stair climbing.
