Driving force distribution control is one of the characteristic performance aspects in-wheel motor vehicles and various methods have been developed to direct yaw moment while turning. However, these controls significantly enhance vehicle dynamic performance, additional power required motion still remains be clarified. This paper constructed new formulae mechanism by which alters cornering resistance mechanical all wheels based on a simple bicycle model, including electric loss motors...
Dehydrothermal (DHT) treatment was used to improve the properties of collagen casings because its non-cytotoxicity. Understanding effects DHT on structure and mechanical films is beneficial developing satisfying casings. Herein, with various temperatures (85–145 °C) timescales (1–7 days) were investigated. It clarified that chemical crosslinking covalent bond between molecules formed after treatment. Crosslinking density increased increasing temperatures, contributing increase tensile...
This paper proposes an efficient direct yaw moment control (DYC) capable of minimising tyre slip power loss on contact patches for a four-independent wheel drive vehicle. Simulations identified significant reduction with due to change in steer characteristics during acceleration or deceleration while turning. Simultaneously, the vehicle motion can be stabilised. As result, proposed method ensure compatibility between dynamics performance and energy efficiency. also describes results...
Human–robot interaction during general service tasks in home or retail environment has been proven challenging, partly because (1) robots lack high-level context-based cognition and (2) humans cannot intuit the perception state of as they can for other humans. To solve these two problems, we present a complete robot system that given highest evaluation score at Customer Interaction Task Future Convenience Store Challenge World Robot Summit 2018, which implements several key technologies:...
As the retail industry keeps expanding and shortage of workers increasing, there is a need for autonomous manipulation products to support operations. The increasing amount customers in establishments such as convenience stores requires automation restocking, disposing straightening products. needs be time-efficient, avoid damaging beautify display In this paper, we propose robotic system restock shelves, dispose expired products, straighten environments. proposed mobile manipulator features...
Today's robotics involves a large range of knowledge and skills across many disciplines. This issue has recently come to light as competitions attract more talented teams tackle unsolved problems. Although the tasks are challenging, preparation cycles usually short. The involved, ranging from academic institutions small startups companies, need develop deploy their solutions with agility. Therefore, this paper introduces containerized Software Development Environment (SDE) based on...
We propose a novel concept of thin and compact CPV modules in which submillimeter solar cells are directly attached to lens arrays without secondary optics or an extra heat sink. With this small cell size, the optical path length module can be brought down one-twentieth that conventional modules. To achieve precise alignment microsolar at focal points, we have developed fluidic self-assembly technique utilizes surface tension. This with triple junction demonstrated efficiency 34.7% under...
Tyre slip power loss has become a key issue for extending the number of miles per charge an electric vehicle can achieve. However, definition and mechanism tyre yet to be defined theoretically. Therefore, this paper analytically clarifies energy equilibrium state when forces are generated using brush model that is widely used in dynamics simulations. The analysis results show input dissipated only sliding region, but amount dissipation equal total mechanical including potential due elastic...
Recent demographic trends in super aging societies, such as Japan, is leading to severe worker shortage. Service robots can play a promising role augment human workers for performing various household and assistive tasks. Toilet cleanup one challenging task that involves complaint motion planning constrained toilet setting. In this study, we propose an end-to-end robotic framework perform tasks related cleanup. Our key contributions include the design of multipurpose end-effector, adaptive...
Robotic systems intended for domestic housekeeping or elderly care tasks will have interaction with humans and therefore demand an intrinsically safe design. Conventional robotic are driven by heavy, high power stiffness electric motors, making them unsafe human coexistence. To overcome this problem, we developed a arm system using pneumatic muscle actuators, which is given its low weight pliant structure. In paper present the design of robot associated control system, showing that has...
