A robot includes a link portion including a plurality of link members and a drive portion to rotate the link members, and axes of rotation of the drive portion extending from end portions of the link members is positioned at an identical point.

In a robot, each of a first flexible member and a second flexible member has a portion fixed to an n-th arm, a portion that is fixed to an (n+1)-th arm, and a portion that is positioned between the n-th arm and the (n+1)-th arm and is wound around a member in a folded state. The portion of the first flexible member that is fixed to the n-th arm is positioned on the member side from the portion of the second flexible member that is fixed to the n-th arm. The portion of the second flexible member that is fixed to the (n+1)-th arm is positioned on the member side from the portion of the first flexible member that is fixed to the (n+1)-th arm.

A robot includes a manipulator including an n (n is an integer equal to or larger than 1)-th member capable of turning around an n-th turning axis, an (n+1)-th member provided in the n-th member to be capable of turning around an (n+1)-th turning axis having an axial direction different from an axial direction of the n-th turning axis, and an (n+2)-th member turnably provided in the (n+1)-th member. The n-th member and the (n+1)-th member are capable of overlapping each other when viewed from an axial direction of the (n+1)-th turning axis. A specific portion of the (n+2) -th member does not intrude into an inside of a first region including a turning center on the (n+1)-th turning axis. The first region includes a singular point of the manipulator and an immovable region of the manipulator.

An arm-shaped structure includes a pipe-shaped main body and an attachment interface joined to at least one end of the main body and securable to another component. At least a portion of the main body and the attachment interface is formed by resin containing a continuous reinforcement fiber. The main body and the attachment interface are joined to each other in a state where relative movement along a longitudinal axis of the main body and around the longitudinal axis is prevented in accordance with engagement between a recess provided in one of the main body and the attachment interface and a protrusion provided in the other one of the main body and the attachment interface.

In one embodiment of the invention, a robotic arm is provided including a linkage assembly and a strap drive train. The linkage assembly includes first, second, third, and fourth links pivotally coupled in series together at first, second, and third joints to define a parallelogram with an insertion axis. The strap drive train includes first and second sets of straps coupled to the linkage assembly. As the linkage assembly is moved about a pitch axis, the first set of straps ensures the third link maintains the same angle relative to the first link, and the first and second set of straps ensures the fourth link maintains the same angle relative to the second link.

A robot arm increases a plurality of arm sections that are turnably connected. The arm sections include a plurality of links and an actuator section that turns the plurality of links. The actuator section includes: a cylindrical cover provided on an outer surface; a motor that turns the plurality of links; a motor frame included in the motor; a reduction gear that decelerates rotation from the motor and outputs a torque; a collar fixed to the reduction gear; and a wire body including at least one of a wire and a pipe. At least a part of the wire body is housed between a surface including a first small body section formed by the motor frame and the collar and a surface including a second small body section of the cylindrical cover.

A reconfigurable robot system employing a base actuator (11), an instrument actuator (12), an end-effector (13) and arm sets (14, 15). Each arm set (14, 15) is operable to successively adjoin the base actuator (11), the instrument actuator (12) and the end-effector (13) into an arc configuration for moving the instrument as held by the end-effector (13) relative to a remote center of motion responsive to the base actuator (11) generating the rotational motion along a primary axis and/or the instrument actuator (12) generating the rotational motion along a secondary axis. Each arc configuration defines the remote center of motion as an intersection of the primary axis, the secondary axis and the longitudinal axis. The arm sets (14, 15) are partially or fully interchangeable for reconfiguring the arc configuration of the base actuator (11), the instrument actuator (12) and the end-effector (13).

A robot includes a robot arm having a first member rotatably provided on a base, a second member rotatably provided on the first member, a third member rotatably provided on the second member, and a fourth member rotatably provided on the third member. The fourth member has an arm rotatable about a rotation axis in an axis direction different from an axis direction of a rotation axis of the first member with respect to the base. In a first state, the first member, the second member, and the third member overlap. In a second state, at least one of a distal end of the robot arm and an end effector provided on the distal end of the robot arm overlaps with the second member.

A three-dimensional (3D) emitting apparatus includes a table on which an object is to be disposed, a robot arm to perform a task on the object, an emitting member provided at an end portion of the robot arm, and a controller to control an operation of the robot arm or a position of the emitting member, wherein the table and the robot arm may move relatively in a vertical or horizontal direction, the emitting member may move along a trajectory of rotation of the robot arm, and the trajectory of rotation may be provided in a form of a concentric sphere having a center at which a target point is disposed.
