A robot arm apparatus includes a base structure, a first arm, a first actuator, and an assisting device. The first arm is pivotable relative to the base structure about a first pivot axis. The first actuator is configured to pivotally actuate the first arm relative to the base structure. The assisting device is configured to apply an assist rotational force to the first arm to assist the first actuator.

Robot arm apparatus and actuator

A robot according to embodiments includes a speed reducer, a first shaft, a rotary electric machine, a second shaft, and a brake. The speed reducer reduces and outputs rotation to be input into an input unit. The first shaft is connected to the input unit. The rotary electric machine rotates the first shaft. The second shaft is connected to the input unit. The brake regulates the rotation of the second shaft.

Robot and robot system

An articulated manipulator includes a base body, a first arm body, a second arm body having a second arm center axis, and a third arm body. A first joint part connects the base body and a first end portion of the first arm body rotatably around a first rotation axis. A second joint part connects a second end portion of the first arm body and a third end portion of the second arm body rotatably around a second rotation axis. A third joint part connects a fourth end portion of the second arm body and a fifth end portion of the third arm body rotatably around the third rotation axis. When the first, second and third arm bodies are all erected with respect to a installation surface, the first rotation axis, the second arm center axis, and the third rotation axis are substantially aligned with each other.

Articulated manipulator

The present invention is an industrial robot with a cable spanned between and end effector and an upper arm. The cable does not twine around the upper arm or interfere with a peripheral device. A passage opening, through which the cable for supplying power, signals, or materials to an end effector attached to a rotating element is drawn out of a body, is opened at a position where the body intersects the center of a first rotational axis.

Industrial robot

This invention provides a manipulator that can facilitate a teaching method, improve the operation speed of an arm, and mount a heavy load in a narrow space. The manipulator includes a plurality of arm bodies provided in series, joint parts rotatably connecting two adjacent arm bodies, and the joint parts in which slope of rotation axes of the adjacent joints are 90 degrees, at least one linear body disposed in the joint parts coaxially with the rotation axes. The joint parts are composed of a servo motor, and a speed-reduction mechanism. The rotation axes of the servo motor, the speed-reduction mechanism and the joint parts become the same axis.

The present invention provides an industrial robot, wherein a cable or the like spanned between an end effector and an upper arm has less bending due to a motion of a wrist portion, wherein the cable or the like does not twine around the upper arm, and wherein the cable or the like does not interfere with a peripheral device. A passage opening, through which a cable or the likefor supplying power, signals or materials to an end effectorattached to a rotating elementis drawn out of a body, is opened at a position, at which the bodyintersects with a center of a first axis (an R-axis). The cable or the likedrawn out of the passage openingis extended to the end effector

There is provided an industrial robot having no interference of a cable for an end effector or the like with a peripheral apparatus. An end effectoris fixed to a wrist flangethrough an intermediate member. The intermediate membertakes the shape of a crankshaft in which a first flangeattached directly to the wrist flange, a second flangeprovided at a predetermined interval in parallel with the first flangeand attached directly to the end effector, and two membersandfor coupling the first and second flangesandare arranged symmetrically.

An arc welding cable that is resistant to bending and twisting and can give a long life is provided. For this purpose, an arc welding cable () for supplying a welding current, a welding wire and a sealed gas from a wire feeding device () to a welding torch (), has a passage () for the welding wire () and sealed gas is located at a center of the arc welding cable and a plurality of conductors () are arranged apart from one another on a circumference around the passage (). The space between the plurality of conductor () may be filled with a cushion material such as cotton or elastic synthetic resin.
