Abstract: A robot includes a speed reducer that increases a first torque output from a motor and outputs a second torque, a torque sensor including an output part that outputs the second torque output from the speed reducer, and a sensor part that detects at least a torque applied to the output part, and a damper that is positioned in a transmission path of the second torque from the speed reducer to the torque sensor and damps transmission of the second torque.

Abstract: A robot includes a base plate rotatable around a rotation axis, a first arm connected to the base plate at a first axis which is perpendicular to the rotation axis and around which the first arm is rotatable, a second arm connected to the first arm at a second axis which is parallel to the first axis and around which the second arm is rotatable, a third arm connected to the second arm at a third axis which is parallel to the first axis and around which the third arm is rotatable, a turnable link connected to the third arm at a fourth axis which is perpendicular to the third axis and around which the turnable link is rotatable, a distal-end swingable portion connected to the turnable link at a fifth axis which is perpendicular to the fourth axis and around which the distal-end swingable portion is rotatable, a distal end connected to the distal-end swingable portion at a sixth axis which is perpendicular to the fifth axis and around which the distal end is rotatable, and a welder connected to the distal end.

Abstract: A robot includes a first arm, a second arm, a third arm, a distal end, a first actuator, a second actuator, a third actuator, and a plurality of posture adjustment actuators. The first arm, the second arm, the third arm, and the distal end are coupled in series to each other. The first actuator is configured to swing the first arm about a first axis line. The second actuator is disposed on a side on which the first actuator is disposed in a direction along the first axis line. The second actuator is configured to swing the second arm about a second axis line parallel to the first axis line. The third actuator is configured to swing the third arm about a third axis line parallel to the first axis line. The plurality of posture adjustment actuators are configured to adjust a posture of the distal end.
