چکیده

Need for increased accuracy and precision in nano/micro movements and other devices (e.g. electronic, microscopy, medical etc.) has led to the development of allied technologies. The performance of these precision devices depends heavily upon accurate micro positioning of various links and joints. This has led to development of associated micro/nano mechanisms. Development of Microfactories needs miniature components, precise linear positioning systems. In all such high precise applications the mechanisms needs to be free from backlash, wear, lubrications and with minimum active components. This paper represents the study related to the design methodology of a flexure based compliant mechanism, a pantograph is offered as an alternative to the existing positioning systems in order to overcome their disadvantages. KeywordsMicromechanisms, Microfactory, Positioning systems, Compliant pantograph

Compliant Leg Design for a Quadruped Robot

malian animals, i.e. that of a cat. It was also influenced by the spring-mass model representation [2]. Compliant prismatic legs show an intrinsic robustness for their angle of attack [2], they have a stability region. If the leg design is changed into a two segmented leg with a specific linear torsional spring, the leg stiffness kleg becomes nonlinear (Fig. 2(b) blue line), similar to that of ...

Towards dynamic trot gait locomotion: Design, control, and experiments with Cheetah-cub, a compliant quadruped robot

We present the design of a novel compliant quadruped robot: Cheetahcub, and a series of locomotion experiments with fast trotting gaits. The robot’s leg configuration is based on a spring-loaded, pantograph mechanism with multiple segments. A dedicated open loop locomotion controller was derived and implemented. Experiments were run in simulation and in hardware on flat terrain and with a step-...

New Designing Procedure for Pantograph of High-Speed Trains

In Japan, several projects to increase train speed are underway, requiring a new generation pantograph that achieves further reduction in aerodynamic noise. However, as reduction of pantograph noise usually conflicts with the stabilization of its lift force characteristics, a number of experiments have to be conducted to develop a new type of pantograph. The aeroacoustic and lift force characte...
