An automobile vehicle flexible robot door hinge installation system includes a hinge servo-linear positioning device. The hinge servo-linear positioning device includes at least one servo-motor and at least one hinge effector releasably holding and positioning a vehicle door hinge. A fastener servo-linear installation device is also provided.

End-of-arm tools to be coupled to a robotic arm and configured to handle structural lumber objects are disclosed as are methods of use for such. The end-of-arm tools comprise opposing jaws to grip the lumber objects. The opposing jaws are coupled to a rigid frame via a four-bar linkage providing mechanical advantage and over-center functionality. An actuated extractor extends between the opposing jaws to engage the lumber object upon release. Assemblies of multiple end-of-arm tools coupled together are also disclosed.

A linear actuator having a housing, a shaft having a proximate end attached to the housing and a distal end which moves relative to the housing, a first attachment point on one of the housing or the distal end of the shaft, a second attachment point connected to the other of the housing or the distal end of the shaft by way of one or more springs, and a motor that is operatively engaged with the shaft to drive movement of the shaft. The linear actuator may be connected within any desired mechanism with at least two parts that move relative to one another, such as a mechanical gripper, by connecting one part to the first attachment point and the other part to the second attachment point.

A refuse vehicle includes a chassis, tractive elements, a lift apparatus, and a reach assembly. The tractive elements couple with the chassis and support the refuse vehicle. The lift apparatus includes a track and a grabber assembly. The track includes a straight portion and a curved portion. The grabber assembly releasably grasps a refuse container and ascends or descends the track to lift and empty refuse into a body of the refuse vehicle. The reach assembly includes an outer member, a first extendable member, and a second extendable member. The first extendable member is received within an inner volume of the outer member and translates relative to the outer member. The second extendable member is received within an inner volume of the first extendable member and translates relative to the first extendable member. The lift apparatus is fixedly coupled at an outer end of the second extendable member.

A rotational driving mechanism for driving a rotary member mounted on a rotatable base member includes: a first link unit that has a first link body and is mounted through a first support part on the base member, the first link unit further having an input part to which an output of the linear motion actuator is inputted at one side of the first link body, and an output part located in the first link body at an opposite side of the input part across the first support part and a second link unit that has a second link body and is mounted through a second support part on the output part of the first link unit, the second link unit being further mounted through a third support unit on the rotary member or a connecting member joined thereto in such a manner as to be free to rotate.

An electrodynamic apparatus includes a first arm extending in a first direction, a second arm supported by the first arm, a linear actuator that moves the second arm along the first direction with respect to the first arm, a support extending in a second direction that is different from the first direction and supporting the first arm, and a rotating mechanism that rotates the support about an axis of rotation parallel to the second direction. The first arm includes a power transmission antenna. The second arm includes a power reception antenna. The power transmission antenna supplies electric power to the power reception antenna wirelessly. In rotating the support, the linear actuator moves the center of gravity of the second arm to the axis of rotation first, and then the rotating mechanism rotates the support.

An electrodynamic apparatus includes a first arm extending in a first direction, a second arm supported by the first arm, and a first linear actuator that is provided in the first arm or the second arm and moves the second arm along the first direction with respect to the first arm. The first arm includes a first power transmission antenna. The second arm includes a first power reception antenna. The first power transmission antenna supplies electric power to the first power reception antenna wirelessly. The first power reception antenna supplies the supplied electric power to a load electrically connected to the first power reception antenna.

An industrial robot includes an actuator and a driver. The actuator serves to provide power inside so as to create a predetermined motional form. The driver serves to drive an internal power source of the actuator to output power. The driver is adjacently and fixedly connected with one end of the actuator. A power unit is disposed in the actuator for generating power. The power unit has an output shaft. The actuator has a transmission unit for transmitting the power to make an operation unit move in the predetermined motional form. The transmission unit has a transmission shaft. The output shaft and the transmission shaft are coaxially and integrally formed.

A piezoelectric actuator includes a plurality of piezoelectric elements that generate a driving force to be transmitted to a driven portion; and a power supply portion that supplies power to the plurality of piezoelectric elements. The plurality of piezoelectric elements are electrically connected to the power supply portion in parallel.

A work device includes a work device body and a contact preventer. The work device body includes a linear motion unit having three degrees of freedom and a rotary unit having three degrees of freedom. An end effector is mounted on an output portion of the rotary unit. The contact preventer separates a working region in which the work device body is installed, from a non-working region outside the working region. The contact preventer includes: an entry allowing portion allowing an object to enter the working region therethrough; and an entry allowing portion entry detection sensor configured to detect entry of an object into the working region through the entry allowing portions.
