摘要:
A telescoping mast able to efficiently extend and retract multiple telescoping sections without jar and minimal energy. The telescoping mast has multiple telescoping sections, a position feedback sensor, a motor, a spring motor, and a computation unit. The position feedback sensor is coupled to at least one telescoping section and configured to identify a position of the telescoping sections. The motor is also coupled to the telescoping sections, and raises and lowers the telescoping sections. The computation unit controls the motor based on the position of the telescoping sections.
