Analysis of User Interaction While Walking on Slopes Using Robotic Rollators – Pilot Study

Robotic rollators (walkers with motor) require appropriate assist performance to improve the quality of life of the elderly and disabled. In this pilot study, the performance of commercial robotic rollators was evaluated by analyzing the effect of load condition on muscle activities and knee and hip joint angle when walking on a slope. Results showed that, the highest muscle activity occurred under a load of 5 kg but there was no difference in joint angle according to load condition. In future studies, we plan to test the performance with many subjects. In addition, we will perform motion analysis and muscle activity analysis according to changes in assist, brake, and speed levels.
