Automatic robot travel usually moves from one place to another and in its journey, it has many challenges such as dealing with many obstacles and intersections. Many studies have focused on how to avoid these obstacles, sometimes this challenge can be solved if the space to turn has a large space because the robot's maneuvering when moving becomes more flexible. But what if the available space has motion space that has a steep and narrow angle of motion such as having turning angles of 45°, 135°, 225°, and 315°. This research will examine sharp turning movements to turn angles of 45°, 90°, 135°, 180°, 225°, 270° and 315° in 7 different rooms according to the angle of the maze using the Petri net model. The final results obtained for sharp turning movement using the Petri net model can be obtained where each model will receive information through the form of a place, transition and token model, following the marking values in room 1 M0 M1 M2, room 2 M0 M1 M3, room 3 M0 M1 M4, room 4 M0 M1 M5, room 5 M0 M1 M6, and room 7 M0 M1 M8 success. © 2022 IEEE.

Real-time location of construction workers is crucial information for site safety management as the construction accidents usually happen instantly when the workers are facing dangerous hazards. Previous methods for developing Real-time Locating System (RTLS) are either imprecise enough or too expensive for practical applications. This paper presents an Image Recognition-based Distance Measurement Technique that achieved 2.13% average error rate or 15 cm distance error. It outperforms other RTLS techniques including RFID, GPS, VA, WLAN, and is close to NFC and UWB but much more cost-effective and easily implemented. © 2021 ECBIOS 2021. All rights reserved.

The term "3D printing" can refer to a variety of processes where material is deposited, joined, or solidified under computer control to create a three-dimensional (3D) object. According to this principle, the material is added (such as fluid molecules or powder grains being fused together), typically layer by layer. One of the key advantages of 3D printing is the ability to produce very complex shapes or geometries, from the simplest to the most complex, that will be otherwise impossible to construct by hand, including hollow parts or parts with internal truss structures to reduce weight. In industries and companies where 3D printing is still a relatively new addition, the polylactic acid (PLA) material is the best option, because it is known in the industry as the easiest filament material to print. It is ideal for those who are looking to carry out fast prototyping, therefore it is the perfect choice for quick work. In this article, the authors intend to establish a set of printing rules for a geometric shape made of polymeric material (PLA) through the 3D printing process for a practical application and to present as much as possible the behavior in time of this printed component that replaces a non-corrosive metal component. © 2022 Wiley-VCH GmbH.

The movement of the robot will be even more challenging if on the mobile journey the robot gets a lot of obstacles, there are many choices to turn left or turn right and be able to go back to the place of origin, for that purpose precise and fast navigation is needed. This research offer new methods robot mobile navigation modeled using the mirror petri net method. This method is the development of the petri net method, which is a graphical and mathematical modeling method that is very suitable for modeling a contradictory movement system. The final result will be obtained a mathematical model with the same marking value, which is used as a mobile robot navigation. This same marking value will have a different meaning when departing and when return. © 2019 Published under licence by IOP Publishing Ltd.

A smart lecture room system is an approach to a complete solution for both building managers and users from a classical lecture room. This project is made to control the access of the lecture room automatically using a magnetic door lock. The system is controlled by the smartphone-based application with Wi-Fi connection. The access control system comes with energy-saving capability which is control the power supply. The system is also equipped with a security attribute as it embedded with motion detectors. This system is for detecting intruders who have no permission to enter the lecture room and make it more secure. Therefore, this device can be applied for general used to improve the current smart lecture room system.

Damper Fault-Tolerant Linear Parameter-Varying Semi-Active Suspension Control

IFAC-PapersOnLine 2017年第1期50卷 8592-8599页

This paper addresses the design of a fault-tolerant semi-active suspension controller. The fault-tolerant properties of the controller are realized by an LPV anti-windup approach using saturation indicator scheduling parameters. The saturation indicators model the force limitations of the semi-active dampers in the LPV framework and thus allow for the synthesis of semi-active suspension controllers with guaranteed closed-loop stability and performance. Additionally, the saturation indicators readily describe damper failures like e.g. oil leakage which extends the controller validity from normal operation to faulty operation modes. This property of the saturation indicator concept is exploited by augmenting the LPV controller by a damper force reconfiguration which explores the weak input redundancy provided by four semi-active dampers. The damper force reconfiguration aims at a maximization of ride comfort performance in the presence of damper failures. The achievable ride comfort improvement is illustrated by a simulation study with a full-vehicle model excited by sine sweeps. © 2017

The Efficacy of State of the Art Overground Gait Rehabilitation robotics: A Bird's Eye View

To date, rehabilitation robotics has come a long way effectively aiding the rehabilitation process of the patients suffering from paraplegia or hemiplegia due to spinal cord injury (SCI) or stroke respectively, through partial or even full functional recovery of the affected limb. The increased therapeutic outcome primarily results from a combination of increased patient independence and as well as reduced physical burden on the therapist. Especially for the case of gait rehabilitation following SCI or stroke, the rehab robots have the potential to significantly increase the independence of the patient during the rehabilitation process without the patient's safety being compromised. An intensive gait-oriented rehabilitation therapy is often effective irrespective of the type of rehabilitation paradigm. However, eventually overground gait training, in comparison with body-weight supported treadmill training (BWSTT), has the potential of higher therapeutic outcome due its associated biomechanics being very close to that of the natural gait. Recognizing the apparent superiority of the overground gait training paradigms, a through literature survey on all the major overground robotic gait rehabilitation approaches was carried out and is presented in this paper. The survey includes an in-depth comparative study amongst these robotic approaches in terms of gait rehabilitation efficacy.

Ecosystem of a freshwater from river or lake can be extremely fragile. Assessment on flows and quality in water system is critical as fresh water mostly come from rivers and lakes. The used of river drifting buoy is new to estuarial and riverine studies compared to the oceanography. The collected river parameters from the drifters benefits the community in term assessment of water quality, usage and storm water control planning. In this work, the river drifting buoy developed were inspired by water-walking arthropods which is water strider. The design drifting buoy were able to control their heading and have the ability to withstand the impact from a deployment at the river banks under several obstacles. The design introduce power efficiency and agile movements on the water surface for deep or very shallow water surfaces. The performance of the buoy were recorded with real data collected at several local area near Batu Pahat. © 2017 IEEE.

When doing selfie photos on the smartphone we will get the image that is contrary to the original photo, to return it sometimes we use the mirror software to get the original photo, based on it we introduce navigation robot using mirror petri net method to do movements that are reversed with the original movement, this method is suitable for the movement of robots that run from the place of origin to another target goal and back to the original place. The marking petri net value of the net entry will be inserted into the rfid tag as a robot navigation.
