During stroller use, there are obstacles on the road, such as bumps and gradients, which pose a risk of accidents due to potential operational errors. Therefore, it is necessary to improve the stroller’s maneuverability and stability to reduce the physical burden on the operator and enhance safety. This study aims to clarify the impact of the camber angle of the stroller’s rear wheels on its maneuverability and stability. The study involved three young male participants and included experiments to measure straight-line performance and assess the muscle burden on the forearm during S-curve driving, investigating the effects of different camber angles. The results showed that straight-line performance was significantly improved at a camber angle of 15° compared to camber angles of 0°, 5°, and 10°. Additionally, the muscle burden on the forearm during S-curve driving decreased as the camber angle increased, with a significant reduction observed at a camber angle of 5°. These findings suggest that adjusting the camber angle of the stroller’s rear wheels can effectively enhance both maneuverability and stability.
