Publication number: 20200114506Abstract: Training and/or using a recurrent neural network model for visual servoing of an end effector of a robot. In visual servoing, the model can be utilized to generate, at each of a plurality of time steps, an action prediction that represents a prediction of how the end effector should be moved to cause the end effector to move toward a target object. The model can be viewpoint invariant in that it can be utilized across a variety of robots having vision components at a variety of viewpoints and/or can be utilized for a single robot even when a viewpoint, of a vision component of the robot, is drastically altered. Moreover, the model can be trained based on a large quantity of simulated data that is based on simulator(s) performing simulated episode(s) in view of the model. One or more portions of the model can be further trained based on a relatively smaller quantity of real training data.Type: ApplicationFiled: December 4, 2018Publication date: April 16, 2020Inventors: Alexander Toshev, Fereshteh Sadeghi, Sergey Levine

Publication number: 20200114507Abstract: A method includes controlling a robot body performed by a controller. The robot body includes a finger, a driving unit, and a detection unit. The driving unit is configured to move the finger. The detection unit is configured to output a signal corresponding to a state of the finger moved by the driving unit. The method includes causing the finger to hold a workpiece, causing the robot body to start a predetermined operation while causing the finger to keep holding the workpiece, if a detected value based on the signal outputted from the detection unit is within a first range, and causing the robot body to continue to perform the predetermined operation until completion of the predetermined operation, if the detected value is within a second range in the predetermined operation. The second range is different from the first range.Type: ApplicationFiled: October 9, 2019Publication date: April 16, 2020Inventor: Shingo Amano
