Claim 4:
5. The device according to claim 1, wherein
the motion sensor includes a second motion sensor to measure a rotation angle of the parallelogram mechanism relative to the base and a third motion sensor disposed on the base; and
to obtain sensor data output by the motion sensor and determine a velocity of the second end in a direction of gravity relative to a ground based on the sensor data, the at least one processor being further configured to:
obtain second sensor data output by the second motion sensor and third sensor data output by the third motion sensor,
determine a rotation angle of the parallelogram mechanism relative to the base based on the second sensor data,
determine a velocity of the base based on the third sensor data, and
determine the velocity of the second end in the direction of gravity relative to the ground based on the rotation angle and the velocity of the base.
