A robotic system is provided for assembling parts together. In the assembly process, both parts are moving separately with one part moving on an assembly base and another part moving on a moveable arm of a robot base. Motion data is measured by an inertial measurement (IMU) sensor. Movement of the robot base or moveable arm is then compensated based on the measured motion to align the first and second parts with each other and assemble the parts together.

Provided is a command value correction device that can reduce positioning error for a robot. A command value correction device according to one embodiment of the present invention corrects a command value for directing the orientation of a articulated robot that positions a tip end of an arm that has a plurality of joints, the device comprising: a robot model setting unit that sets a robot model that represents the articulated robot with an elastically deformable model; a support model setting unit that sets a support model that represents a support, to which the articulated robot is secured, with an elastically deformable model; a force calculation unit that calculates a force that acts on the support by the weight of the articulated robot if the orientation of the articulated robot follows the command value prior to correction; and a correction unit that corrects the command value so as to cancel out elastic deformation of the support model due to the force calculated by the force calculation unit.

A robot includes a base, a robot arm having a first arm coupled to the base and rotating about a first axis, and a force detection unit provided in the base and detecting a force acting on the base or the robot arm, wherein the first arm is coupled to the base in a position shifted from a first center line passing through a center of the base and being parallel to the first axis, and a second center line passing through a center of the force detection unit and being parallel to the first axis is closer to the first axis than the first center line.

A teaching method is for teaching a position and attitude of a robot arm to a robot configured to switch between a first state where the third axis is located at one side of a first imaginary line and a second state where the third axis is located at the other side of the first imaginary line, the first imaginary line being set as a straight line passing through a first axis and a second axis when the robot arm is viewed from a direction along the first axis. The method includes performing a switching operation of switching between the first state and the second state according to a result of detection by a force detection unit.
