We describe a patient with extracutaneous pyoderma gangrenosum (PG), who presented with chest pain. Histological examination showed extracutaneous neutrophilic infiltration of the spleen and lung, with later findings of PG.
We are conducting a feasibility study on a semi-autonomous maintenance robot for power distribution lines that works using task instructions. We are analyzing the task of “switch gear installation” in power distribution lines maintenance and describing a task scenario for it. We are also designing a controller for the robot system. In the controller, the tasks are described using robot motion commands...
We are developing semi-autonomous robot system for power distribution line maintenance tasks to ensure worker's safety and improve efficiency of task performance. This robot system works with task level instructions, for example, “Insert the bolt”.
We are developing a semi-autonomous robot system for a power distribution line maintenance tasks. The robot system executes primary tasks autonomously when the operator directs tasks, for example “Pull out the insulator”. In this paper, we propose the method for aligning the gripper to the insulator. The proposed method for alignment is as follows: 1) The gripper at the top of the arm approaches the...
We are developing a semi-autonomous robot system for a power distribution line maintenance tasks and making task performance tests. If you execute a task for example “inserting bolt”, the robot system works autonomously. When we direct “Remove insulator”, in the vision system detects an insulator using a camera image, and then the robot arm approaches the insulator. This camera is fixed at end effector...
This paper describes how to insert a bolt in power distribution maintenance tasks. The present system has about 1 cm margin error between CG (computer graphic) and real environment. The arm holding the bolt approaches to the position above a bolt hole under position control and inserts the bolt under compliance control.
We are developing a Semi-Autonomous Remote Maintenance Robot for power distribution line maintenance tasks. The system is operated by task instructions; for examples, “Peeling electric cable cover”, “Remove the insulator” and so on. When the system receives a task instruction it measures the task object position; modifies the arm positions in the move commands; and then performs the task. In this...
