Power Substations

Purpose With the dramatically increasing number of substations, robots are expected to inspect equipment in the power industry. However, a traditional robotic system cannot work stably because of the strong electromagnetic field in substation. The purpose of this paper is to present a robust and stable robotic system for inspecting the substation equipment without the involvement of workers. Design/methodology/approach The paper presents in detail a robotic system that consists of a monitor center and a robot. With the monitor center, the workers could send inspection tasks and monitor status of the robot timely. Once a fault is detected, the alarm message will flash immediately to remind the workers. The patrol mode of the robot comprises teleoperation, regular inspection, special inspection and a key return mode. The robot only relies on a low-cost magnetic sensor for lateral positioning and radio frequency identification technology for longitudinal positioning when working under patrol mode. At each stop point, the substation equipment can be recognized quickly through accurate matching with the template image stored in the database. Findings It is shown that the robot could work efficiently and reliably in power substations. The positioning error is proved to be within 5 mm, compared to that of 20 cm by implementing integrated global positioning system-dead reckoning navigation. Because of the high positioning accuracy, it is much easier to recognize the substation equipment. It is observed that nearly 99 per cent of equipments can be recognized. Research limitations/implications The proposed robotic system is tested in a simple substation environment. While the proposed system shows satisfactory positioning results, further studies considering changeable weather condition will focus on improving the equipment recognition rate in such environment, such as rainy, snowy and strong sunlight. Practical implications The key contribution of this paper is that it provides a robotic system to inspect substation equipment instead of workers, to improve working efficiency and to reduce manpower cost. Originality/value This paper presents a robotic system to inspect substation equipment instead of workers. Four patrol modes are designed to meet the inspection demand. Comparing with the previous robotic systems, this system contributes to higher position accuracy and higher equipment recognition rate.

Abstract. Fresh market apple harvesting is a difficult task that relies entirely on manual labor. Much research has been done on the development of mechanical harvesting techniques. Several selective harvesting robots have been developed for research studies, but there are no commercially available robotic systems. This article discusses the design and development of a novel pneumatic 3D-printed soft-robotic end-effector to facilitate apple separation. The end-effector was integrated into a robotic system with five degrees of freedom that was designed to simplify the picking sequence and reduce costs compared to previous versions. Apples were successfully harvested using the low-cost robotic system in a commercial orchard during the fall 2017 harvest. A detachment success rate on attempted apples of 67% was achieved, with an average time of 7.3 s per fruit from separation to storage bin. By conducting this study in an orchard where problematic apples were not removed to increase the detachment success rate, current pruning and thinning practices were assessed to help lay the foundation for future studies and develop strategies for successfully harvesting apples that are difficult to detach.

LOW-COST ROBOTIC SYSTEM FOR PREPARATION OF LAYER-BY-LAYER FILMS. Layer-by-Layer is an efficient technique for the deposition of thin films used in several devices such as sensors, solar cells, and other systems. A robotic system improves the process reproducibility, be a stand-alone system, and does not demand human participation during the deposition process. On the other hand, the commercially available equipment is expensive. In this work, we present a low-cost robotic system built by using materials commonly found that allows performing several bathing, drying steps and deposition cycles of the substrates necessary for the formation of LbL films. This technical note presents the electronic assembly scheme and the program developed for an experiment. The number of baths, the time necessary for the deposition, and repetitions to result in the formation of the desired film; can be easily modified in this program. The films prepared in this experiment were successfully employed for the preparation of compact layers for perovskite solar cells. Therefore, the equipment can be easily customized to the needs of each research group that uses it.

In robotic industry, today, interactions between human and machine usually consists of programming and maintaining machine using human operator. Using a robotic system in any industry for work provides precision and a certain level of accuracy. A robotic entity such as a robotic arm will not ask for time out and can work efficiently day and night which will in turn increase efficiency in workplace. In this paper, we have explained about an arm created, which works in such a way that while the robotic arm is working, camera is able to identify any object it sees which is taken care by the worker looking over the arm. The major outcome and result is the increased efficiency in workplace, precision and accuracy in low cost which can also be used for house hold chores too.

A stereo visual servo robotic system is developed on Nios II SOPC developing board with ALTERA FPGA chip to manipulate a retrofitted Mitsubishi RV-M2 robotic system. The 3-D position information between the target and stereo vision system can be extracted by low cost CMOS stereo vision algorithm first. Then, the relative motion between the robotic end-effector and the target can be planned to guide robot arm to catch the object. The fuzzy sliding mode control algorithm is employed to monitor the trajectory motion of each joint. The experimental results show that this visual servo robotic system can track and catch a moving target in 3D space and execute some interaction functions with player.

Current vascular intervention inevitably exposes a large amount of X-ray to both an operator and a patient during the procedure. The purpose of this study is to propose a new catheter driving system which assists the operator in aspects of less X-ray exposure and convenient user interface. For this, an assembly-type 4-degree-of-freedom master–slave system was designed and tested to verify the efficiency. First, current vascular intervention procedures are analyzed to develop a new robotic procedure that enables us to use conventional vascular intervention devices such as catheter and guidewire which are commercially available in the market. Some parts of the slave robot which contact the devices were designed to be easily assembled and dissembled from the main body of the slave robot for sterilization. A master robot is compactly designed to conduct insertion and rotational motion and is able to switch from the guidewire driving mode to the catheter driving mode or vice versa. A phantom resembling the human arteries was developed, and the master–slave robotic system is tested using the phantom. The contact force of the guidewire tip according to the shape of the arteries is measured and reflected to the user through the master robot during the phantom experiment. This system can drastically reduce radiation exposure by replacing human effort by a robotic system for high radiation exposure procedures. Also, benefits of the proposed robot system are low cost by employing currently available devices and easy human interface.
