る、上記マニピユレータにあっては、非常に重要な問題
となる。(Conventional technology) In extreme environments such as the deep sea, outer space, and nuclear reactors, where humans are forced to physically enter, machines are sometimes operated remotely. There are various types of machines used in this case, ranging from simple transportation equipment such as cranes to so-called manipulators, which have functions similar to the human arm. In extreme environments, it is often necessary to pay close attention to the work, and it is necessary to improve the operability of the mechanism operated by humans, that is, the master arm. This is a very important problem for the above-mentioned manipulator, which is designed for particularly complex work.

のグリップが取付けられている。Japanese Unexamined Patent Publication No. 173184/1984 discloses one of the master arms used as a control device for such a manipulator.
Two development examples have been disclosed. In this example, three mutually orthogonal axis rotations are added to the third axis (vertical axis direction: 2 axes) of three mutually orthogonal translational axes stacked like a block build. The mechanism that rotates the machine is also attached in a block-built manner, and the last stacked part of the elements that make up this rotating mechanism is attached with a grip for the operator to grasp.

への力を絶縁することが難しく、回転運動のみを希望し
ているにもかかわらず並進運動が発生しがちであった。However, in such a mechanism, it is difficult to independently determine the positioning operation by the translation mechanism and the posture determination operation by the rotation mechanism. For example, to position the lowest translational axis in this block build configuration, the operator must apply force to the grip, first positioning the three rotational axes, then the remaining two translational axes. The operating force must be conveyed through the process. Therefore, when operating the desired axis, there was a high possibility that other axes that were originally intended to be fixed would also move. Furthermore, when trying to fix the translation axis and apply operating force only to the rotation axis, that is, when trying to change the posture of the wrist while fixing a certain spatial position, the rotation mechanism section Since it is mounted on top of the translation mechanism, it is difficult to isolate the force to the translation axis, and translational movement tends to occur even though only rotational movement is desired.
回転運動を並進運動と完全に絶縁しようと思えば、ブレ

する必要があった。If rotational motion was to be completely isolated from translational motion, it would be necessary to add mechanisms such as a brake device or a device to stop signal transmission.

作性の低下を招く恐れがあった。These matters not only complicate the master arm mechanism, but also pose a risk of reducing operability when working in extreme environments that require careful attention.

上述の如く、従来の一般的なマスタアームにあっては、

When attempting to determine a point in space and the attitude at that point completely independently, interference between them is unavoidable.
This has caused problems such as making precise positioning difficult or complicating operations and mechanisms.
そこで本発明は、操作者に複雑な手順を要求することな
く、更に機構的な複雑化を伴わずに、並進を主体とした
位置決め動作と回転を主体とした姿勢決め動作を互いの

とにある。Therefore, the present invention is capable of performing positioning operations mainly based on translation and posture determining operations mainly based on rotations without interfering with each other, without requiring complicated procedures from the operator or complicating the mechanism. The objective is to provide separately configurable master arms.

を拘束する機構から構成されている。(Means for Solving the Problems) The mask arm according to the present invention has three directions of translation in space.
It is comprised of a moving mechanism and a rotating mechanism that operate in three rotational directions, and a mechanism that is attached to the translational movement mechanism and restrains the forearm of the operator.

回転移動機構部上のグリップを操作者は握る。(Function) When the operator determines the spatial position and posture using the master arm according to the present invention, the restraining mechanism attached to the translational movement mechanism of the master arm is attached to the operator's forearm,
Preferably, the area near the wrist joint of the forearm is pinched. The operator grasps a grip on the rotational movement mechanism, which is attached, for example, in a block-built manner, to the tip of the translational movement mechanism.

持したままでスレーブアームの姿勢変更が可能となる。With such a configuration, when the operator attempts to determine one spatial point, the operating force is transmitted to the translational movement mechanism of the master arm via the restraint mechanism of the operator's forearm, and this A so-called translational movement of the slave arm, which is driven in response to a command signal from the master arm, is realized. At this time, since no blade is applied to the operator's wrist joint, there is no risk of the operating force being transmitted to the rotational movement mechanism of the master arm. Conversely, even when trying to stop the translational movement and transmit only the rotational movement, it is possible to perform the rotational movement of the 0 joints between the wrists without any movement of the entire arm. The posture of the slave arm can be changed while maintaining its position.
マスタアームの回転移動運動の内、手首のロール動作に
は手首関節だけではなく前腕部の撓骨と尺骨に依る前腕

干渉が生じることはない。Among the rotational movements of the master arm, the roll movement of the wrist involves rotation of the forearm not only by the wrist joint but also by the radius and ulna of the forearm.In this case, the forearm restraint mechanism is moved in the roll direction. If it is made rotatable, there will be no interference with translational movement.

段が講じられる。A Y-axis translation mechanism +21 and a Z-axis translation mechanism (3) are stacked in this order, and a rotational movement mechanism (4) in the directions of α, β, and γ is attached to this Z-axis translation mechanism. The operator is
Depending on the grip (5) attached to this rotational movement mechanism being grasped with the palm (6), operating force must be applied to these rotational movement mechanisms and translational movement mechanisms. At this time, for example, if you try to apply a rotational force in the α direction,
There is a possibility that the force is also transmitted to the Y-axis translation mechanism and the Z-axis translation mechanism, and if you want to avoid this danger, you can use a brake or signal transmission stop device (not shown) to send a command signal in the translation direction. Measures are taken to prevent the signal from being transmitted to the slave arm.

可能である。FIG. 82 is a diagram showing an outline of when an operator operates a master arm according to an embodiment of the present invention. In this figure, only the elements related to explaining the operation are shown, and other parts are omitted or the parts of FIG. 1 are modified to the extent that confusion is not caused in order to make the explanation easier to understand. (The shaded area in the same figure corresponds to the part shown in Figure 1.) The operator places the forearm along the arm frame and inserts the forearm near the wrist into the forearm restraint mechanism (8). ,Y,
A force corresponding to the Z-axis direction is generated at the wrist of the forearm, and the three-direction translation mechanism is operated via the forearm restraint mechanism. At this time, the shape of the inner surface of the forearm restraint mechanism is preferably made of a deformable material such as rubber so that the shape matches the unevenness of the forearm wrist, and the shape is adjusted in the longitudinal direction of the forearm (i.e., the Y-axis direction).
It is possible to apply sufficient operating force even when moving. According to this configuration, when the operator performs such a translational movement, there is no need for the operator to grasp the grip with the palm of the hand, which was essential with the conventional master arm shown in FIG.
Translational positioning commands are possible without using a rotational movement mechanism.

。The rotational movement mechanism (4) instructs rotation in α, β, and r directions around the rotary joint (7), and the position of this rotary joint is set near the wrist joint position, and the operator transmits the natural movement of the wrist. Preferably, the design is such that the intersection of the rotational axes coincides with the position of the wrist joint. Further, the inner surface of the forearm restraint mechanism (8) is provided with a mechanism that is rotatable in the direction so as not to become an obstacle when the operator performs a roll motion (rotation in the r direction) of the wrist.

進動作と回転動作の干渉は最少限にとどめられる。Regarding the rotational motion command in the β direction, it becomes possible to set the posture of the master arm in the same way that a human can determine the posture of the wrist regardless of the position of the forearm. That is, the translational movement and rotational movement of the master arm can be almost completely isolated. Regarding rotation commands in the r direction that include twisting of the forearm, interference between the translational motion and rotational motion can be kept to a minimum by providing the above-mentioned mechanism that is rotatable in this direction.
