Motion Characteristics

Underwater gliders are a class of Autonomous Underwater Vehicles (AUVs) that offer many advantages over traditional AUVs. Previous research has mainly focused on underwater gliders with fixed wings. This paper studied a novel underwater glider whose wings can pitch independently about its installed shaft, called Movable-Winged Underwater Glider (MWUG). A 6-DOF model of dynamics for MWUG was developed based on Newton’s law and Euler’s equation, gravity, buoyancy, added mass forces and hydrodynamic forces considered. Longitudinal motion simulations were conducted to clarify the motion characteristics of MWUG. Results of the simulations indicated that compared to fix-winged gliders, MWUGs show a smaller glide angle and attack angle, higher glide speed and efficiency

To perform mission in variant environment, several types of mobile robot has been developed an implemented. The mobile robot HILARE is a known wheeled mobile robot which has two fixed wheels and an off-entered orientable wheel. Due to extended application of this robot, its dynamic analysis has attracted a great deal of interests. This article investigates dynamic modeling and motion analysis of the mobile robot HILARE. As the wheels of the robot have kinematic constraints, the constraints of wheels are taken into consideration and the matrix form of the kinematic model of the robot is derived. Furthermore, dynamic model of the robot is developed by consideration of kinematic constraints. To derive dynamic equations of the robot, the Lagrange multiplier method is employed and the governing equations of the robot in state-pace form are presented. Then, some simulations are presented to show applicability of the proposed formulation for dynamic analysis of the mobile robot HILARE.

Abstract Most of the anatomical mathematical models that have been developed to study the human knee are either for the tibio-femoral joint (TFJ) or patello-femoral joint (PFJ). Also, most of these models are static or quasistatic, and therefore do not predict the effects of dynamic inertial loads, which occur in many locomotor activities. The only dynamic anatomical model that includes both joints is a two-dimensional model by Tumer and Engin [1]. The model by Abdel-Rahman and Hefzy [2] is the only three dimensional dynamic model for the knee joint available in the literature; yet, it includes only the TFJ and allows only for rigid contact.
