Movable container, associated electronic device and associated method

A movable container (10) includes: a driving mechanism (W_l-W_4, 211-214, 215), a sensing device (310), and a control circuit (320). The driving mechanism (W_l-W_4, 211-214, 215) is arranged to provide a momentum to the movable container (10). The sensing device (310) is arranged to sense a motion feature in accordance with the momentum provided by the driving mechanism (W_l-W_4, 211-214, 215). The control circuit (320) is coupled to the sensing device (310) and the driving mechanism (W_l-W_4, 211-214, 215), and arranged to calculate a calculated mass of the movable container (10) in accordance with the motion feature sensed by the sensing device (310). The control circuit (320) is coordinated with the driving mechanism (W_l-W_4, 211-214, 215) and the sensing device (310) via a user input. An electronic device (20) communicating with the movable container (10). A method calculating the weight of the movable container (10).
