Background/Objectives: For motions in off-road navigation, including sandy or wet natural environments and space explorations legged machines, mimicking anatomy of legged animals are efficient. However, the traditional full-actuated legged robots are heavy with complex actuation and control systems, as for each degree of freedom separate actuator is used. The purpose of this work is to develop a kinematic model using a single-actuator for hexapod legged robot taking advantage of bio-inspiration and mechanism design techniques. Methods/Statistical analysis: A vector analysis method was used for measuring the system kinematics equations. The simulation of the walking process was performed using MATLAB. A real prototype of the system has been fabricated based on the design, which is not bulky due to use of single motor, and does not require complex control and sensor systems. Findings: Simulations showed that the kinematic model along with the hypothesis on the ground interaction describes the locomotion, which can be used where robots with low-speed repositioning are required. Theoretical analysis, virtual prototype simulations, as well as initial experiments with the physical prototype, showed an efficient functionality of the system. Novelty/Applications: The design and kinematic model can be used for developing low-energy environmental robots for remote areas with occasional relocation requirements. Keywords: Biomimetic environmental robot; kinematic analysis; mechanism design; tripod gait; walking mechanism

The objective of this article is to model the mechanism of a gate in the baggage section of an urban public transport vehicle. The model corresponding to this mechanism responds in a general way to the model of a four-bar articulated mechanism. This model considers the kinematic and dynamic analysis, using the closed vector loop method to represent the closed sum of certain vectors; such as the bars of the mechanism. Additionally, the dynamic analysis of the mechanism must be described by the equations corresponding to Newton's second and third law of motion developed for each mechanism element. These equations have been solved using MATLAB software, those results were taken as theoretical, and were compared with those obtained by a simulation using ADAMS software, object-oriented design software. The results obtained have a low error percentage. The results obtained are useful to make a more detailed design of the mechanism, allowing to optimize the force required to produce the movement and the trajectory that describes it.

Hinge mechanisms of vehicles can be designed and manufactured in various ways in the automotive industry. The hinge mechanisms serve in assembling of tailgates, which are operated manually or automatically and expected to fulfil the functions such as lockability during vehicle service life, strength, impermeability etc., to vehicle bodies. In this study, a new alternative design of tailgate hinge mechanism was proposed in order to remove the shortcomings of the mechanisms used at the current bus tailgates. Positioning, velocity and acceleration analyses of the proposed mechanism were conducted as analytically and computer aided. In addition, the prototype productions of new hinge mechanism were applied to Skyliner model buses which are produced at MAN Türkiye A.Ş.. Moreover, the applicability of the new hinge mechanism into different applications were discussed in terms of the criteria such as easiness of opening and closing of the tailgate under ordinary and extraordinary loads, strength of mechanism in response to weight reduction efforts etc. by the findings obtained.
