整に時間を要する欠点があった。Conventional balance control devices are constructed in this way, so it is necessary to set the moment of inertia to correspond to the weight of the object to be gripped.If the moment of inertia is not constant, the stopping position of the arm may vary depending on the difference in the moment of inertia. There was a drawback that caused a difference. In addition, the position of the weight must be adjusted each time in order to provide a constant moment of inertia to the arm, which has the disadvantage of requiring time for adjustment.

のである。This invention was made in order to eliminate such drawbacks of the conventional ones, and a container containing a magnetic fluid for a weight is attached to a rotating member that rotates while holding an object to be transported, and the magnetic fluid is The balance control device quickly controls the moment of inertia of the rotating member by controlling the field generator that controls the movement of the object using the moment of inertia control device according to the moment of inertia of the rotating member holding the transported object. This is what we provide.

a) (lla) is a coil wound around iron cores (10&) to (10(1)) that moves the magnetic fluid in the container (7) by the magnetic field generated by energization, and (6) is the moment of inertia of the arm (2). is detected and a predetermined coil (tta) ~ (t t
This is a moment of inertia control device for determining the position of the magnetic fluid (3) by energizing the magnetic fluid (3).
なおその他の411I或は第1図に示す従来のものと同

その位置にあるコイル(11G)に通電され磁界が形成
される。この磁界によって磁性流体(3)が移動しロボ
ットの腕(2)の慣性モーメントカ一定に保持される。With this configuration, when the robot's hand (3) grasps the object to be grasped (6), the moment of inertia of the robot's arm (2) is detected by the moment of inertia controller @, and the magnetic fluid (3) is The position to move is determined,
The coil (11G) at that position is energized and a magnetic field is formed. This magnetic field moves the magnetic fluid (3) and keeps the moment of inertia of the robot arm (2) constant.
ここで磁性流体(3)の移動時に容器(7)内において

に移動される。Here, when the magnetic fluid (3) is moved inside the container (7), the internal pressure of the left and right containers (7) of the magnetic fluid (3) is
9), the pressure becomes the same and the magnetic fluid (3) is moved smoothly.

荷重を小さくすることができる。Although this embodiment shows the case where the iron core is wound around the container (7), the same effect can be obtained with a rod-shaped iron core. A device for adjusting the moment of inertia was installed on the same side as the robot's hand (3) with respect to the center of rotation of the robot's arm (2), but on the opposite side to the side where the hand (3) is located. Even if it is provided and adjusted so as to be balanced with respect to the rotation center, not only the same effect can be obtained, but also the bending moment applied to the support base serving as the rotation center and the unbalanced load on the rotation shaft can be reduced.
