Robot motion planning accounting for object pose estimation accuracy
Methods, systems, and apparatus, including computer programs encoded on computer storage media, for planning robotic movements to perform a given task while satisfying object pose estimation accuracy requirements. One of the methods includes generating a plurality of candidate measurement configurations for measuring an object to be manipulated by a robot; determining respective measurement accuracies for the plurality of candidate measurement configurations; determining a measurement accuracy landscape for the object including defining a high measurement accuracy region based on the respective measurement accuracies for the plurality of candidate measurement configurations; and generating a motion plan for manipulating the object in the robotic process that moves the robot, a sensor, or both, through the high measurement accuracy region when performing pose estimation for the object.
METHOD OF CONTROLLING ROBOT APPARATUS, ROBOT APPARATUS, AND METHOD OF MANUFACTURING ARTICLE
A robot apparatus includes: a robotic arm provided with a robotic hand capable of changing its position and its orientation by using joints; a visual sensor which measures a position or an orientation of a gripped object gripped with the robotic hand at a measurement teaching point; and a control device. The control device controls the position or the orientation of the gripped object when the gripped object is attached to an attachment target object at a corrected teaching point corrected based on a measurement result by the visual sensor. In this case, the control device determines a measurement teaching point, where the measurement with the visual sensor takes place, such that a driving direction of each of the joints from the measurement teaching point to the corrected teaching point is set to a definite driving direction.
ROBOT CONTROL APPARATUS, ROBOT CONTROL METHOD, ROBOT SYSTEM, AND STORAGE MEDIUM
A robot control apparatus for controlling a robot manipulating a target object includes a measurement unit configured to measure a change of a gripping unit configured to grip the target object when the gripping unit contacts the target object, a first acquisition unit configured to acquire the change of the gripping unit measured by the measurement unit, a second acquisition unit configured to acquire a gripping state, which is a state of gripping of the target object by the gripping unit, based on the change of the gripping unit acquired by the first acquisition unit, and a control unit configured to control an action of the robot based on the gripping state acquired by the second acquisition unit.
Robotic apparatus, interchangeable tool, and method for controlling robotic apparatus
An interchangeable tool including a finger of a shape suitable for various components is mechanically detachably mounted to a robot arm. This eliminates the need for seeking the origin of the actuator for each interchange. By interchanging fingers themselves, the entire end effector can be reduced in size and weight.
PARAMETER ADJUSTMENT DEVICE, PARAMETER ADJUSTMENT METHOD, AND PROGRAM
Three-dimensional measurement data is obtained (step S1). The poses of bulk parts are calculated (step S2). The gripping poses of a hand relative to the bulk parts are calculated (step S3). Individual evaluation indices are calculated (step S4). Overall evaluation indices are calculated (step S5). The gripping poses are sorted using the overall evaluation indices (step S6). The calculated gripping poses appear on a screen (step S7). The gripping poses are sorted by a user in an intended order (step S8). Determination is performed as to whether the difference between the results of the sorting in step S6 and in step S8 is small (step S9). In response to the difference being sufficiently small, parameters used in the calculation of the overall evaluation indices are stored (step S11). In response to the difference not being sufficiently small, the parameters are updated (step S10) and the processing returns to step S5.
FULLY AUTOMATED ASSEMBLY AND CONTACTING OF ELECTRICAL COMPONENTS
An automated assembly and contacting of electrical components are disclosed. Before a fed component is gripped, a control device of a mounting device for mounting and contacting electrical components is provided with information associated with the component comprising, in relation to a component coordinate system of the component, the position, orientation and a relevant length of electrical connections of the component, and the position and type of handling of the handling locations of the component. A position and an orientation of the component in relation to a machine coordinate system are known to the control device. Using the position and the orientation of the component in the machine coordinate system, the control device converts the positions and orientations defined by the information associated with the component into the machine coordinate system and takes the positions and orientations into account when gripping and assembling the component.

Grasping apparatus, grasping determination method and grasping determination program
A grasping apparatus brings a hand unit to a standstill after performing a grasping motion for a target object that deforms when being grasped, performs a determination operation of making an arm unit move and displace the whole hand unit so that a part of the target object that is not grasped by the hand unit may cover a specific spot, and determines that the hand unit has successfully grasped the target object when an observation unit can no longer observe the specific spot after starting the determination operation.
