In this study, a placement-position search technique for robot-executable, space-efficient packing of various objects with a robot manipulator has been developed. The technique is used to enable placing objects in order from the corner of a container, fulfilling the following conditions: (A) the corner is within the reach of a robot manipulator, and (B) the robot manipulator does not collide with...
We have prototyped a mobile dual-arm robot and an automated order picking system including the robot for warehouses that contain various kinds of products. By using self-localization, model-based object recognition and arm trajectory planning, the robot can autonomously move to the front of the shelf that has a target product, fetch the product from the shelf and put the product in a carton transported...
This paper describes a Kalman filter for a class of linear system in which: 1) The sampling time of measurement is longer than the control period. 2) The measurement is delayed. Using the delayed measurement and the present and past time predicted state, the pseudo-measurement in present time is constructed. The optimal Kalman gain is designed to minimize the trace of the covariance of estimation...
This paper presents a control method that makes it possible for a home-use manipulation system to easily grasp objects with various weights and hardnesses. To provide easy operability for nonprofessional persons, an action-intention-based man-machine interaction method was developed. To enable the fine finger-force control required for grasping various objects, a combined optical-mechanical tactile...
To achieve fast and accurate positioning control, a controller based on a visual servo employing a multi-rate Kalman filter was implemented and experimentally evaluated. Although a visual servo is expected to achieve robust positioning control by eliminating positional errors due to operation environments, applying visual information to positioning control faces three challenges, namely, lower sampling...
A robotic-hand controller with operating performance scalable according to the number of connected tactile sensors was developed. To eliminate performance bottlenecks that appear with increasing number of sensors, the controller architecture adopts multiple processors connected in a loosely-coupled hierarchical structure. Moreover, to maximize operation throughput of the system, a technique for gathering...
