[Object] To reduce output of a motor of a support arm device. [Solution] A support arm device includes: a first drive part configured to be fixed to a base part and cause a first drive shaft to perform shaft rotation; a second drive part configured to be fixed to the base part and cause a second drive shaft to perform shaft rotation; and an arm part including at least one parallel link and configured to support a predetermined tool. The arm part is caused to change an attitude to cause the predetermined tool to perform a predetermined rotational motion by the first drive part and the second drive part being driven.

A portable programmable machine enhances efficiency and ergonomics associated with conducting otherwise manual operations within confined spaces. A main body supports a programmable telescoping arm configured to extend through an access port to reach a confined space. The arm includes an articulating wrist for holding and manipulating tools for autonomously processing work parts. The machine can also act semi-autonomously to accommodate interventions of an operator for overriding and fine-tuning interaction of a tool with a work part for proper processing of the part. The arm communicates with a computer in the main body for processing numerical data, and the operator may use a reference camera to fine tune any particular process. The machine incorporates multiple processing functions, for example collar swaging, nut running, cleaning, and/or application of sealants, all through an aircraft wing access port. The main body has lockable wheels for securing the main body near the access port.

Systems and methods for transferring a micro device or an array of micro devices to or from a substrate are disclosed. In an embodiment, a remote center robot allows on-the-fly alignment between a micro pick up array and a target substrate. The remote center robot may include a plurality of symmetric linkages that move independently and share a remote rotational center. In an embodiment, the remote rotational center may be positioned at a surface of the micro pick up array to prevent damage to the array of micro devices during transfer.

A robot includes a robot body and a feeding cable. The robot body is disposed in an explosion-proof region. The feeding cable is disposed in the explosion-proof region, and power is supplied to the robot body through the feeding cable. The feeding cable includes a plurality of wires and a cover. Each of the plurality of wires includes a conductor and an insulator covering the conductor. The cover covers the plurality of wires and has a thickness of equal to or greater than 10 percent of an outer diameter of the feeding cable.

A force multiplier (5) configured to assist movement of the operating rod (22) in its axial direction is provided. An engagement recess (52) provided on an outer periphery of the operating rod (22) has a cam surface (52a) configured to make engagement with an engagement ball (51). There is provided a support hole (53) configured to allow movement of the engagement ball (51) in a radial direction of operating rod (22) and to restrict movement of the engagement ball (51) in the axial direction of the operating rod (22). A pressing member (54) configured to press the engagement ball (51) is provided, and the pressing member (54) has a force-multiplying surface (54a).

Devices, systems, and methods for positioning an end effector or remote center of a manipulator arm by floating a first set of joints within a null-perpendicular joint velocity sub-space and providing a desired state or movement of a proximal portion of a manipulator arm concurrent with end effector positioning by driving a second set of joints within a null-space orthogonal to the null-perpendicular space. Methods include floating a first set of joints within a null-perpendicular space to allow manual positioning of one or both of a remote center or end effector position within a work space and driving a second set of joints according to an auxiliary movement calculated within a null-space according to a desired state or movement of the manipulator arm during the floating of the joints. Various configurations for devices and systems utilizing such methods are provided herein.

Devices, systems and methods of controlling movement of a host mechanical system using inertial forces imparted by an augmentable or morphable appendage. Such appendages are attached to the host mechanical system such that augmentation or morphing of the appendage to move a mass of the appendage from an extended to a retracted configuration imparts inertial forces to the supporting structure. Augmentation/morphing is controlled and coordinated such that imparted inertial forces facilitate a desired movement of the mechanical system. The imparted forces can include translation forces and/or rotational forces along one or more axes. The augmentation or morphing of the appendage can be performed concurrently with separately controlled coordinated movement of the appendage to facilitate a desired movement of the mechanical system. Such appendages can include, but are not limited to, telescoping and/or folding designs.

A robot includes: an n-th arm (where n is at least one integer equal to or greater than 1) that includes a first portion and a second portion having a portion extending in a different direction from the first portion and is rotatable around an n-th rotation axis; and an (n+1)-th arm that is installed in the n-th arm to be rotatable around an (n+1)-th rotation axis as a different axis direction from a axis direction of the n-th rotation axis. The second portion is located closer to the (n+1)-th arm than the first portion. The n-th arm and the (n+1)-th arm are overlapable when viewed in the axis direction of the (n+1)-th rotation axis. The n-th rotation axis and the (n+1)-th rotation axis are separate from each other. A length of the (n+1)-th arm is equal to or less than 80% of a length of the second portion.

Provided is an arm fixing device that includes: a bracket having close-contact surfaces that are brought into close contact with a mounting surface provided in a supporting member, and a mounting surface provided in an arm or a link for transmitting drive force to an arm, also having one of a screw hole or a through hole that is formed to penetrate each of the close-contact surfaces at a position corresponding to a position of the other of a screw hole or a through hole provided in each of the mounting surfaces, and bridged over the mounting surfaces such that each of the close-contact surfaces is brought into close contact with a corresponding one of the mounting surfaces; and a fastener that penetrates the through hole and is fastened to the screw hole.

An example system includes an apparatus (i) configured for connection to a robot or (ii) integrated into the robot. The apparatus includes at least one structure configured for connection to one or more corresponding accessories. The at least one structure includes (i) a protrusion that extends outwardly relative to a surface associated with the robot or (ii) an indentation that extends inwardly relative to the surface associated with the robot. The at least one structure may include one or more faces that are tapered such that each of the one or more faces decreases in width farther away from the surface associated with the robot.
