ROBOT MOTION PLANNING DEVICE, ROBOTIC SYSTEM, AND METHOD

According to one embodiment, a robot motion planning device includes processing circuitry. The processing circuitry receives observation information obtained by observing at least part of a movable range of a robot. The processing circuitry determines, in a case where first observation information is received, a target position to which the robot is to make a motion, using an action-value function and the first observation information. The processing circuitry receives measurement information obtained by measuring a state of the robot, calculates a difference corresponding to the first observation information, using the measurement information, and determines a motion plan of a force-controlled motion of the robot, based on the target position and the difference.

MACHINING ROBOT AND MACHINING METHOD

A robot control system according to an embodiment is a control system for a robot comprising an arm, the arm being capable of holding a tool while rotating the tool and capable of moving the tool in at least two-dimensional directions, the arm being equipped with a rotating mechanism provided for the tool. The robot control system comprises a load-acquiring unit and a control-signal-generating unit. The load-acquiring unit is configured to acquire a force measured by a force sensor configured to measure a force applied from the tool to the arm during profile copying performed on a machining object by moving the arm while a copying guide attached to the arm and a copying mold placed on the machining object are kept in contact with each other. The control-signal-generating unit is configured to automatically control the arm by generating a control signal for the arm in accordance with the force acquired by the load-acquiring unit and with control information for the arm regarding the profile copying, and by outputting the control signal to the arm.

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.

Software Center and Highly Configurable Robotic Systems for Surgery and Other Uses

Telerobotic, telesurgical, and/or surgical robotic devices, systems, and methods employ surgical robotic linkages that may have more degrees of freedom than an associated surgical end effector in space. A processor can calculate a tool motion that includes pivoting of the tool about an aperture site. Linkages movable along a range of configurations for a given end effector position may be driven toward configurations which inhibit collisions. Refined robotic linkages and methods for their use are also provided.

Learning force limits of items for use in GCU optimization

Described herein are techniques for optimizing gross cubic utilization of inventory space by compressing items into closer proximity. In some embodiments, the inventory system selects an initial force limit to which an item to be stored may be subjected. The inventory system may cause a robotic arm to grasp the item and to push that item into a determined storage location. The inventory system then pushes the item into the storage location while applying a force up to the initial force limit to the item. While monitoring the position of the item, the inventory system may detect that the changes in position of the item are decreasing or stopping and determine that the item is approaching its force limit. The inventory system then updates database records with the force limit associated with the item.

20240131701 · 2024-04-25 ·

Movement of an object can occur while a control system corrects for compliance within a robotic system. The control system can include the object to be moved, the robotic system that moves the object, a primary sensor positioned on the object, at least one ancillary sensor positioned on the object, and a controller. The sensors can record position and orientation data at different points on the object. The controller can use a sensor data and a delta value to correct for compliance in the robotic system. The delta value can be based on the differences between the primary sensor and the at least one ancillary sensor. The compliance correction can be applied to poses of the object to modify the trajectory of the object for more accurate movements.
