A robot includes a plurality of joints including a first joint and a second joint that rotates in a direction different from a rotation direction of the first joint, a plurality of arm members including a first arm member provided to be rotatable with respect to a base via the first joint, and a first angular velocity sensor provided in the first arm member or the first joint. A first inertial sensor is provided in the first arm member (or a portion that rotates together with the first arm member in the first joint). The plurality of joints are controlled on the basis of an output of the first inertial sensor.

Robot

A robot includes a base, a first arm which is rotatable around a first rotating axis with respect to the base, a second arm which is rotatable around a second rotating axis orthogonal to the first rotating axis, a third arm which is rotatable around a third rotating axis parallel to the second rotating axis, a first angular velocity sensor provided in the first arm, and a second angular velocity sensor provided in the third arm. The angle between a detection axis of the first angular velocity sensor and the first rotating axis is a predetermined first angle. The angle between a detection axis of the second angular velocity sensor and the second rotating axis is a predetermined second angle.

Robot, robot control device, and robot system

A robot has an operation mode setting unit that sets an operation mode of the robot. The operation mode setting unit changes a correction factor multiplied by the maximum acceleration and the maximum deceleration of an arm and the servo gain of a servo circuit, and thereby selectively sets the operation mode to one of a first operation mode, a second operation mode in which the arm operates faster than in the first operation mode, and a third operation mode in which the arm vibrates less than in the first operation mode.

Robot and robot controller

A robot-position detecting device includes: a position-data acquiring unit that acquires position data indicating actual positions of a robot; a position-data input unit that receives the position data output from the position-data acquiring unit; and a position calculating unit that calculates a computational position of the robot through linear interpolation using first and second position data input to the position-data input unit at different times.

Robot-position detecting device and robot system

A position detection device for a horizontal articulated robot includes a camera for imaging the robot or a work as an imaging object, a control section for calculating a location of the imaging object from an image, an acquisition section (I/O) for obtaining the drive amounts of first and second electric motors of the robot, and a storage section for storing the calculated location of the imaging object and the drive amounts so as to correspond to each other. A common trigger signal for detecting the location of the imaging object is input to the camera and the I/O. The camera starts to image the imaging object in response to the input of the trigger signal. The I/O starts to obtain the drive amounts in response to the input of the trigger signal.
