  • Differential-velocity driving device and mechanical arm to which the differential-velocity driving device is applied
    Patent number: 9140344
    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.

  • Joint device and control method thereof
    Patent number: 8616088
    Abstract: A joint device includes a rotary shaft, two fixing members, two driving members, two transmission gears, and a link gear. The two driving members are respectively fixed to the two fixing members, and the two fixing members are pivoted to each other through the rotary shaft. The two driving members are respectively connected to and drive the two transmission gears. The link gear is pivoted to the rotary shaft and engaged with the two transmission gears respectively, so that the two driving members are in a transmission relation. The joint device adopts the combination of dual driving members and gear sets, thereby achieving the high reactivity and high load function.
