As the agricultural population ages and declines, the demand for mechanized equipment to reduce labor intensity has increased. This study presents the design of a lightweight electric transport cart that operates in accordance with the walking speed of elderly workers and evaluates its structural safety and driving feasibility. The target driving speed was set to 0.7 m/s, and the frame was designed using aluminum alloy 6061-T6 for weight reduction. Structural analysis using ANSYS under a payload condition of 20 kg showed that the maximum equivalent stress was 87.547 MPa, which is lower than the yield strength of the material. Subsequently, dynamic analysis considering unpaved road driving conditions was conducted using ADAMS, confirming that the cart reached the target speed of 0.7 m/s within 0.8 s under a driving torque of 3.0 N·m.
