This paper presents the conceptual and functional design of a novel hybrid leg-wheel-track ground mobile robot for surveillance inspection, named WheTLHLoc (Wheel-Track-Leg Hybrid Locomotion). The aim work is development general-purpose platform capable combining tracked locomotion on irregular yielding terrains, wheeled with high energy efficiency flat compact grounds, stair climbing/descent a...

This paper presents an advanced leg module developed for, HRP-2, a new humanoid robotics platform, which has been developed in the phase two of the Humanoid Robotics Project(HRP), a five year program sponsored by the Ministry of Economy, Trade and Industry of Japan (METI) from 1998FY to 2002FY. The biped locomotion ability of HRP-1, the humanoid robotics platform developed in the phase 1 of HRP...

The intention of this paper is twofold. It first describes the robotic platform AloF and its control software framework which was designed for autonomous locomotion in rough terrain. The robot has a very large range of leg motion to actively explore its surroundings through haptic interaction and to increase its locomotion capabilities. The platform is robust enough to carry adequate sensors to...

Digital platform owners repeatedly face paradoxical design decisions with regard to their platforms’ generativity and control, requiring them facilitate co-innovation whilst simultaneously retaining control over third-party complementors. To address this challenge, deploy a variety of governance mechanisms. However, researchers practitioners currently lack coherent understanding what major mech...

This article proposes modeling, simulation and kinematic and workspace analysis of a spatial cable suspended robot as incompletely Restrained Positioning Mechanism (IRPM). These types of robots have six cables equal to the number of degrees of freedom. After modeling, the kinds of workspace are defined then an statically reachable combined workspace for different geometric structures of fixed a...

Among various types of floating offshore wind turbines (FOWTs), the tension leg platform (TLP) have relatively small motions due to stiff tendons. Similar TLP applications in industry, tendon failure may lead deteriorated stability and large transient responses, which should be considered as part accidental limit state (ALS) checks at design stage FOWTs. This paper takes WindStar system a repre...

The hanging droplet technique for three-dimensional tissue culture has been used for decades in biology labs, with the core technology remaining relatively unchanged. Recently microscale approaches have expanded the capabilities of the hanging droplet method, making it more user-friendly. We present a spontaneously driven, open hanging droplet culture platform to address many limitations of cur...

The fouetté turn in classical ballet dancing is a continuous turn with the whipping of the gesture leg and the arms and the bending and stretching of the supporting leg. The knowledge of the movement intensities of both legs for the turn would be favorable for the conditioning of the dancer's body. The purpose of this study was to estimate the intensities. The hypothesis of this study was that ...

This paper describes the modeling, simulation, and control of an inverted, ceiling-mounted Stewart platform, designed to be a one-person motion simulator. The dynamic equations of the Stewart platform are derived using the virtual work principle. It is shown by simulations that the leg dynamics can be neglected. A model of the electrohydraulic actuator is derived and then veri ed using experime...

Leg-length inequality is an extensively studied complication of total hip arthroplasty in normal patients. However, few studies have focused on the pelvic obliquity of coronal pelvic malrotation. We hypothesized that pelvic obliquity with a fixed abduction/adduction contracture deformity of the hip may intraoperatively affect the release of soft tissues, ultimately resulting in a leg-length ine...
