Development of Cart With Providing Constant Steerability Regardless of Loading Weight or Position: 4th report: Simulation for combining translational and rotational movement.

This study proposes a shopping cart system with constant steerability regardless of the loading weight and position. Conventional carts are often affected by varying loads, necessitating corrective steering or exertion of excessive operating force, leading to decreased comfort and safety. To address these challenges, we propose a steering assist system that integrates passive robotics concepts. In this paper, we present a steering control method that combines translational and rotational movements. Furthermore, we validate this proposed method by utilizing a steering simulator that we have developed.
