Abstract: A robot includes: a base; a first arm rotatably coupled to the base about a first axis of rotation; a second arm rotatably coupled to the first arm about a second axis of rotation, the second axis of rotation being an axis perpendicular to the first axis of rotation or being an axis parallel to an axis perpendicular to the first axis of rotation; a third arm rotatably coupled to the second arm about a third axis of rotation, the third axis of rotation being an axis parallel to the second axis of rotation; a first angular velocity sensor installed to the first arm and having an angular velocity detection axis parallel to the first axis of rotation; and a second angular velocity sensor installed to the third arm and having an angular velocity detection axis parallel to the third axis of rotation.

Abstract: A robot includes a base, a first arm that rotates around a first rotation axis, a second arm that rotates around a second rotation axis extending in a direction different than the first rotation axis, a third arm that rotates around a third rotation axis extending in a direction parallel to the second rotation axis, a first inertia sensor at the first arm, a second (a) inertia sensor at the third arm, a first angle sensor at a first drive source, a third angle sensor at a third drive source, and the drive sources rotate the respective arms. Angular velocities from the first inertia sensor and the first angle sensor are fed back to a first drive source control unit. Angular velocities from the second (a) inertia sensor and the third angle sensor are fed back to a second drive source control unit.

Abstract: A robot includes a base, first and second arms, first and second drive sources, first and second inertia sensors, and first and second angle sensors. A rotation axis of the first arm and a rotation axis of the second arm are orthogonal to each other. The first inertia sensor is installed at the first arm, and the second inertia sensor is installed at the second arm. The first angle sensor is installed at the first drive source, and the second angle sensor is installed at the second drive source. Angular velocities obtained from the first inertia sensor and the first angle sensor are fed back to a first drive source control unit. Angular velocities obtained from the second inertia sensor and the second angle sensor are fed back to a second drive source control unit.
