Abstract:
A differential-velocity driving device and a mechanical arm to which the differential-velocity driving device is applied are provided. The differential-velocity driving device includes a first rotary driving element, a first transmission gear connected to the first rotary driving element, a second rotary driving element, a second transmission gear connected to the second rotary driving element, a fixing member connected to the first rotary driving element and the second rotary driving element such that the first rotary driving element does not move or rotate with respect to the second rotary driving element, a power output gear engaged with the first transmission gear and the second transmission gear, and an output shaft passing through an axle center of the power output gear and being coaxial with the axle center.
