In this paper, we propose an information model supporting maintenance schedule coordination that flexibly accepts operators' requirements without any impact on other classes.
This paper a study of a vehicle that goes over small objects by indoor. Recently, the robot industry market has spread. Among them, many companies advancing the introduction and utilization of service robots purpose to the substitution of human work. Consequently, only 60% answered that they were achieved results. The reason for the low results is that conventional robots do not have enough size, traveling performance and positioning accuracy. In this study, after examining the robot implementation and the conventional robot, we aim at the one that functions sufficiently the size, traveling performance and omnidirectional movement within the indoor environment. To this end, we propose a vehicle that can move in omnidirectional and can move each foot independently in the vertical direction. In the experiment of this study, a distance sensor was attached to the foot to detect the front floor height. When the floor height fluctuated, it was considered that there were small objects, and the foot was raised according to the height of them, and they were gone over. As a result, the sensor could detect small objects and realize the going over action. In the future, we aim to realize autonomous driving by combining it with the technology of omnidirectional movement.
Today's robotics involves a large range of knowledge and skills across many disciplines. This issue has recently come to light as robotics competitions attract more talented teams to tackle unsolved problems. Although the tasks are challenging, the preparation cycles are usually short. The teams involved, ranging from academic institutions to small startups and large companies, need to develop and deploy their solutions with agility. Therefore, this paper introduces a containerized Software Development Environment (SDE) based on a collaborative workflow relying on open-source technologies for robotic system integration and deployment. The proposed SDE enables the collaborators to focus on their individual expertize and rely on automated tests and unattended simulations. The analysis of the adoption of the proposed SDE shows that several research institutions successfully deployed it in multiple international competitions with various robotic platforms.
An omnidirectional camera can simultaneously capture all-round (360°) environmental information as well as the azimuth angle of a target object or person. By configuring a stereo camera set with two omnidirectional cameras, we can easily determine the azimuth angle of a target object or person per camera on the image information captured by the left and right cameras. A target person in an image can be localized by using a region-based convolutional neural network and the distance measured by the parallax in the combined azimuth angles.
Functional surfaces have been widely used for control of physical and/or chemical properties of substances on the surface. The surface functions have been controlled by coating or the other processes in terms of material treatment so far. Recently, the advanced micro fabrications have also been applied to manufacturing of the functional surfaces. This study presents a fabrication of the micro scale structures on surfaces in millings with end mills having textured edges. In the fabriacation, the end mill is fed back and forth with controlling the spindle axis inclination alternately. The textured edge was finished on a PCD end mill in laser processing with reducing the irradiation diameter on a developed machine. The cutting tests were conducted to verify the presenting fabrication with the end mill, on which the texture shape is formed with a pitch of 10 μm at an apex angle of 90 degrees. The micro asperities were fabricated on surfaces with nealy the same size as the texture one of the edge.
The field of robotics involves extensive knowledge and skills related to numerous fields, and the World Robot Summit benchmarks technical skills in service robotics through competition. While grasping and moving a wide variety of objects, we examine a new method for handling objects using a suction mechanism. Notably, the proposed mechanism utilizes the adhesion force resulting from Stefan adhesion, which occurs when a solid plate detaches from a smooth surface. Experiments are conducted to evaluate the performance of the adhesion hand, and the obtained results demonstrate its effectiveness.
Outdoor mobile robots are faced with the more diverse environmental changes than indoors.Tsukuba challenge is one of the biggest experiments for the outdoor autonomous vehicle technology. The result of outdoor robot mapping has a deformation (warping) for measurement errors. In this paper, we deal with the loop closing problem of the warped robotic map.
