In this work, we present a method involving the fast grasping of an unknown object by a mobile robot with a parallel-jaw gripper. A 2D range sensor is installed on the robot at an inclined angle to acquire partial shape information regarding the unknown objects. The candidate grasping points for an unknown object can then be determined by directly extracting features from this partial shape information...
Task completion time and cost are two significant criteria for the selection of manipulator system. For a given task, several Pareto solutions of manipulator systems should be derived based on the evaluation of these two criteria. However, this process requires a large calculation time. In this paper, we propose a method that can select appropriate systems by evaluating task completion time and cost...

Minimizing the task completion time of manipulator systems is essential in order to achieve high productivity. In this paper, this problem is dealt with by utilizing the redundant degrees of freedom (DOF) of a given task and the tool attachment optimization. For example, in a vision-based inspection where a camera is held by a manipulator, the extra DOF can be brought about by allowing the camera...
This paper addresses a rearrangement problem by a group of mobile robots and proposes a method for task assignment and path planning applicable to different kinds of environment. The method minimizes task completion time considering complexity of robot's paths in achieving the goal state of a working environment. It minimizes the number of possible delivery tasks between robots thereby reducing the...
This paper presents a work on fast robotic grasping by a mobile robot based on partial shape information of an object. The information is acquired by a laser range finder installed on the robot at an inclined angle. Feature data are extracted by scanning part of the object to calculate the grasping point. The robot grasps the object without needing to acquire and process all of the object information...
The minimization of task completion time of robot arms has been an extensively studied area in robotics. Previous researches mostly focused on optimization methods for the motion planning and collision avoidance, which did not involve any modifications in the hardware design of a robot arm. Some researches, on the other hand, fully design a specialized robot arm for a given task. In this study, we...
