A robot arm includes a robot hand including a hand base to which first and second finger connection portions are connected, and a finger moving portion to move the first and second finger connection portions with respect to the hand base such that a distance between a first finger and a third finger increases or decreases. A rotation axis rotating the hand base passes through a midpoint between fingertips of the first finger and the third finger while the first finger and the third finger are perpendicular to the hand base. the robot arm includes a forearm and a wrist joint to connect the robot hand to the forearm rotatably with two rotational degrees of freedom or one rotational degree of freedom. The forearm is rotatable around a forearm rotation axis that passes through the forearm and is the rotation axis that allows the hand base to be rotated.

A robot hand operation device through which an operator inputs an operation instruction to move a robot hand including at least three fingers includes: a main body portion held by the operator; and joysticks each being corresponded with each of the fingers of the robot hand to be operated and provided in the main body portion in a number that is the same as that of the fingers. When the operator operates each of the joysticks, the operation instruction to move the finger corresponded with the each of the joysticks is inputted, and when the operator does not operate each of the joysticks, the operation instruction to move the finger corresponded with the each of the joysticks is not inputted.

A robot arm operation device is mounted on an upper arm, a forearm, and a hand of an operator and through which the operator inputs, by moving the robot arm operation device, an operation instruction to operate a robot arm to a control calculation device that controls the robot arm. The robot arm operation device includes: a shoulder joint angle measurement part to measure a shoulder joint measurement angle being an angle at which an upper arm structure is connected to an arm connection structure at a shoulder measurement joint; an elbow joint angle measurement part to measure an elbow joint measurement angle being an angle at which a forearm structure is connected to the upper arm structure; and a wrist joint angle measurement part to measure a wrist joint measurement angle being an angle at which a hand structure is connected to the forearm structure.

A robot hand includes a first finger, a third finger disposed to face the first finger, a second finger disposed side by side with the third finger, a first finger connection portion to which the first finger is connected rotatably, a second finger connection portion to which the second finger is connected rotatably and to which the third finger is connected rotatably, a hand base to which the first finger connection portion and the second finger connection portion are connected, and a finger moving portion that moves at least one of the first finger connection portion and the second finger connection portion with respect to the hand base such that a distance between the first finger and the third finger increases or decreases.

A remote control manipulator system includes: a manipulator being controlled by an operator remotely to handle an object; a stereoscopic display device that displays a right-eye image and a left-eye image so as to be stereoscopically viewed; a model image generator that generates a model image being an image of an integrated three-dimensional model viewed from a viewpoint designated by the operator, the integrated three-dimensional model being a three-dimensional model obtained by integrating the manipulator model and a surrounding environment model being generated by performing image processing on the right-eye image and the left-eye image and being a three-dimensional model of the object and a surrounding environment thereof; and a model image display device that displays the model image and is configured to be able to be viewed by the operator switching between the stereoscopic display device and the model image display device through moving the head of the operator.

Remote control manipulator system and remote control assistance system

A preload guide system guides, in a horizontal plane, movement of a rotation structure having journals rotating around a rotation axis having a horizontal rotation shaft. At right-side surfaces of the journals, guide bearing components press predetermined positions on the same side with respect to an axial-direction reference plane and rotatably support the journals. At left-side surfaces of the journals, guide bearing components press positions corresponding to the guide bearing components at the right side surfaces, and rotatably support the journals. The support systems adjust displacement amounts of the guide bearing components such that a sum of the displacement amounts becomes zero.
