Provided is a method for controlling a robot including a base, a robot arm coupled to the base, and a drive unit including a motor for driving the robot arm. The method includes a first step of acquiring target position information on a target position when the robot arm is moved; a second step of determining a frequency component to be removed from a drive signal for driving the motor based on a posture of the robot arm at the target position of the acquired target position information; and a third step of removing the frequency component determined in the second step from the drive signal to generate a correction drive signal.

Techniques for controlling position of an end effector of a robotic device relative to a virtual constraint

A robotic device includes one or more actuators to position an end effector in a plurality of degrees of freedom. A navigation system tracks an actual position of the end effector. A controller identifies a condition wherein the actual position of the end effector contacts a virtual constraint. The controller determines that an anticipated movement of the end effector from an actual position to the home position would cause a collision between the end effector and a virtual constraint and computes a target position of the end effector that avoids the collision. The target position is spaced from the actual position and computed with respect to the virtual constraint. The one or more actuators are controlled to move the end effector from the actual position to target position along the virtual constraint.

Automated teaching of pick and place workflow locations on an automated programming system

The operator may first place a blank device in a first socket in a first site. The APS may self-teach the position and orientation of that first socket by removing and replacing the device in the socket one or more times, and by detecting the position of the device in the socket or by monitoring a change in position of the device as it is placed into the socket. The APS then picks the device from the first socket (or from the input tray) and moves it in succession through the rest of the sockets to establish position and orientation of each socket. After all sockets are taught, the APS loads all sockets with blank devices, and programming begins. Alternatively, the programming job begins as each site is taught and before the remaining sites are taught so that production output can begin “immediately.”
