Trajectory control apparatus and trajectory control method for intra-planar multifreedom SCARA type of robot, and computer-readable recording medium with trajectory control program for intra-planar multifreedom SCARA type of robot stored therein

In a trajectory control method for an intra-planar multifreedom SCARA type of robot, a positional increment for an arm tip is computed for a linear interpolating operation through the expression described below. Namely, the expression is Vn=L.sub.1 .multidot.sin(.theta..sub.2).multidot.J.sub.1, wherein Vn indicates a positional increment of an arm tip; L.sub.1 indicates a length of a first arm; .theta..sub.2 indicates an angle of a second joint; and J.sub.1 indicates an angular velocity of a first joint (instructed angular velocity) specified by a user.

System and method for robot supervisory control with an augmented reality user interface

Described is a system for robot supervisory control. The system includes an operator device that receives camera imagery from a camera mounted on a robot and three-dimensional (3D) data from a 3D sensor mounted on the robot. The user interface displays a two-dimensional (2D) view of the scene from the camera and 3D sensor data. One or more object markers of objects in the scene are overlaid on the 2D view or 3D sensor data. Viewing the scene, the user can choose a robotic action from a library of actions, which generates a simulation of the robot performing the selected action. The simulation is then rendered and overlaid on top of the 3D sensor data. Moreover, the simulation shows the expected variability of the robot's action. Based on the simulation's outcome, the user can approve and trigger the execution of the action in the real robot.

Efficient Teleoperation of Mobile Robots via Online Adaptation

Described herein is a framework for efficient task-agnostic, user-independent adaptive teleoperation of mobile robots and remotely operated vehicles (ROV), including ground vehicles (including legged systems), aircraft, watercraft and spacecraft. The efficiency of a human operator is improved by minimizing the entropy of the control inputs, thereby minimizing operator energy and achieving higher performance in the form of smoother trajectories by concurrently estimating the user intent online and adaptively updating the action set available to the human operator.

A robot hand is designed to open or close fingers using a linear actuator disposed in a housing. The robot hand has linear motion shafts extending from inside to outside the housing through guide holes formed in a wall of the housing. Each of the fingers includes a base portion and a tip portion. The base portions are secured to the linear motion shafts outside the housing. The tip portions are bent inwardly from the base portions in directions in which they approach each other and then extend toward tips of the fingers. A sealing member is disposed between each of the linear motion shafts and a corresponding one of the guide holes to hermetically isolate the inside of the housing from the outside thereof. This structure achieves an increased degree of sealing of the housing and is capable of having an increased opening or closing stroke of the fingers.

Workpiece identification method

Whether or not workpieces are present in a workpiece storage area is determined based on an image acquired by image capturing. When the workpieces are determined to be present, whether or not a crossing part is present in the workpiece storage area is determined based on the image, the crossing part being a part where soft body portions of a plurality of workpieces cross each other in an overlapping manner. When the crossing part is determined to be present, an uppermost soft body portion placed at an uppermost position among the soft body portions crossing each other is determined based on the image. A workpiece including the uppermost soft body portion thus determined is determined as an uppermost workpiece placed at an uppermost position.
