The tubular-member passes through the hollow-part, one end of which is fixed to the input-shaft or the output-shaft, and the other end of which protrudes from the input-shaft or the output-shaft. The output-side encoder includes a scale and a sensor. The scale is fixed to the tubular-member; and the sensor is fixed to the input-shaft or the output-shaft.

A piece of equipment for on-demand food preparation, for instance on an assembly line, that can use an end-of-arm tool to retrieve and deposit food items on a horizontal surface, such as the surface of a conveyor. The end-of-arm tool may include a peel, in which the peel can be translated from a retracted position to an extended position to transfer food items. The piece of equipment may translate the peel quickly into the extended position to facilitate the retrieval of food items from the horizontal surface. The piece of equipment may be rotated to position the robotic appendage and the peel in a desired direction. The peel may include a push bar that may be movable between a withdrawn position and a push position to selectively push items off of the peel.

A robotic joint wherein a second link is driven relative to a first link. An intermediate link connects the second link to the first link. The first link includes a first arcuate surface centered on a first axis. The second link includes a second arcuate surface centered on a second axis. The radius of the first arcuate surface is equal to the radius of the second arcuate surface. The intermediate link is pivotally connected to the first axis and pivotally connected to the second axis. First and second cables are provided. The first cable runs around the first arcuate surface in a first direction and runs around the second arcuate surface in a second direction that is opposite to the first direction. The second cable runs around the second arcuate surface in the first direction and around the first arcuate surface in the second direction. Tension is maintained on both cables.

Robot sealing structure includes a shaft end face of a shaft of a reducer, an attachment surface of an arm member, bolts for fixing the shaft and the arm member to each other, and a seal member arranged between the shaft end face and the attachment surface, a hollow hole including a center axis line of the shaft is provided in the shaft end face, an input gear housing portion for housing an input gear, and a gear housing portion for housing a gear driven by the input gear are provided in a periphery of the hollow hole, the periphery of the hollow hole is provided with a protruding portion formed between the input gear housing portion and the gear housing portion, and a hole for temporarily attaching or fixing the seal member in the protruding portion is provided.

A deployable multi-section boom comprising a first hinge assembly including a base section adapted to be attached to a structure, a movable section that is pivotably attached to the base section and a first boom attached to the movable section. The first hinge assembly is configured to allow the first boom to pivot in a first direction to a first predetermined maximum angle with respect to the base section. A first constant torque assembly constantly urges the first boom to pivot in the first direction and includes a component attached to the base section of the first hinge assembly. The multi-section boom includes a second hinge assembly that includes a first section attached to the first boom and a second section that is pivotably attached to the first section. A second boom is attached to the second section of the second hinge assembly wherein the second hinge assembly allows the second boom to pivot in a second direction to a second predetermined maximum angle with respect to the first boom. A second constant torque assembly constantly urges the second boom to pivot in the second direction and includes a component that is attached to the first section of the second hinge assembly. The first constant torque assembly and second constant torque assembly cooperate to configure the multi-section boom in a fully deployed state wherein the constant torque applied to the first boom causes the entire multi-section boom to pivot in the first direction while the constant torque applied to the second boom causes the second boom to simultaneously pivot in the second direction with respect to the first boom while the entire multi-section boom continues to pivot in the first direction. The multi-section boom is fully deployed when the first boom pivots to the first predetermined maximum angle and the second boom pivots to the second predetermined angle.

A robot includes a main body provided with a traveling unit, a body display unit disposed on an upper portion of a front side of the main body and elongated in a vertical direction, a head display unit rotatably connected to an upper portion of the body display unit, a rotary motor disposed inside the body display unit, a rotational shaft elongated in a vertical direction and rotated by the rotary motor to rotate the head display unit, and a speaker disposed inside the body display unit, spaced apart from the rotary motor, and overlapping the rotational shaft in a horizontal direction. The robot selectively receives various types of service modules to provide different services.

A robotic arm assembly includes a main body, a number of servos arranged within the main body, each of which has an output shaft, and a rotary connection member connected to the output shaft of one of the servos at a first end of the main body. The rotary connection member defines a through hole allows cables to pass therethrough.

An articulating end-of-arm tool includes back-drive capability. The tool has a cable drive including a vertically oriented capstan head, a pair of idler pulleys, a driven pulley and a tensioner. The driven pulley pivot on a hollow shaft, through which a vacuum channel passes. The vacuum channel extends through the length of the body, including past the vertically oriented motor. The driven pulley is within 10 degrees of perpendicular of the longitudinal axis of the tool.

An arm assembly includes a servo coupled to the chest of the robot, an upper arm driven by the servo, a forearm rotatably coupled to the upper arm, and a forearm transmission member comprising a first end rotatable with respect to the chest and a second end coupled to the forearm. The upper arm, the forearm and the forearm transmission member are arranged in such a way that the forearm rotates when the upper arm rotates with respect to the chest.

A wrist of a robot arm includes a proximal end side connecting body, a first wrist link that rotates about a first wrist axis, a second wrist link that rotates about a second wrist axis, a distal end side connecting body that rotates about a third wrist axis and is connected to an end effector, and a wrist drive device including a drive source and interlock device. The interlock device causes the second wrist link to rotate by 2 about the second wrist axis and causes the distal end side connecting body to rotate by when the first wrist link rotates by arbitrary from a state where the first and third wrist axis overlap. Extending directions of the first, second, and third wrist axis are parallel to a predetermined plane, and a distance from the first to second and from the second to third wrist axis are equal.
