the quasi-static gait is a common walking strategy for legged robots. It can make the legged robots adapt to many structured terrains. Many researchers focus on the quasi-static gait for Quadruped Robots which show great efficiency and simplicity. But when applied to biped robots, the stability analysis and the gait planning are still two challenging issues. this paper focuses on the quasi-static gait for biped walking. A novel gait withthe sinusoidal movement of the center of gravity is proposed to achieve smooth and fast quasi-static walking. Based on the relationship of ZMP and COG, we proposed a stability criterion for quasi-static walking and a method that adjusts the parameters of the walking pattern to achieve fast walking. the proposed method is validated by simulation analysis in VREP software. the results show that biped robots can have well-performed on flat ground.

Free and Open Source software (FOSS) has become the fundamental infrastructure of mainstream software projects. FOSS is subject to various legal terms and restrictions, depending on the type of open source license in force. Hence it is important to remain compliant withthe FOSS license terms. Identifying the licenses that provide FOSS and understanding the terms of those licenses is not easy, especially when dealing with a large amount of reuse that is common in modern software development. Since reused software is often large, automated license analysis is needed to address these issues and support users in license compliant reuse of FOSS. However, existing license assessment tools can only identify the name and quantity of licenses embedded in software and thus cannot identify whether the licenses are being used safely and correctly. Moreover, they cannot provide a comprehensive analysis of the compatibility and potential risk that come withthe term conflicts. In this paper, we propose DIKE, an automated tool that can perform license detection and conflict analysis for FOSS. First, DIKE extracts 12 terms under 3,256 unique open source licenses by manual analysis and Natural Language Processing (NLP) and constructs a license knowledge base containing the responsibilities of the terms. Second, DIKE scans all licenses from the code snippet for the input software and outputs the scan results in a tree structure. third, the scan results match the license knowledge base to detect license conflicts from terms and conditions. DIKE designs two solutions for software with license conflicts: license replacement and code replacement. To demonstrate the effectiveness of DIKE, we first evaluate withthe term extraction and responsibility classification, and the results show that their F1-scores reach 0.816 and 0.948, respectively. In addition, we conduct a measurement study of 16,341 popular projects from Github based on our proposed DIKE to explore the conflict of license us

Rotational slippage due to the gravitational torque is common in grasping tasks using a parallel gripper. To pick the object with a specific desirable grasp pose, if the parallel gripper cannot provide enough force to eliminate the gravitational torque, rotational slippage will cause the manipulation failure. this paper presents an approach to eliminate rotational slippage by pivoting an object on a supporting surface to a pose where it can be picked up, while minimizing the gravitational torque. For evaluation we compare the proposed method with a simple grasping approach, which lifts the object directly, without avoiding slippage. Extensive experiments conducted across both simulation, and real-world environments show that our approach can significantly reduce the rotational slippage problem and help in completing several pick-and-place tasks.

More than 30 years ago feature models were invented. Nowadays they play a major role in software Product Line engineering. Although there have been several attempts to establish a standard approach (e.g., OVM, CVL, TVL,..) there is still no consensus on a simple feature modelling language. However, such a language would improve information sharing among researchers and tool developers. Following the spirit of the previous six editions, this workshop is an interactive event where all participants share knowledge, ongoing realizations, and improvements concerning the Universal Variability Language (UVL) to further increase its outreach.
