Insights into how exactly a fly powers and controls flight have been hindered by the need to unpick the dynamic complexity of the muscles involved. The wingbeats of insects are driven by two antagonistic groups of power muscles and the force is funneled to the wing via a very complex hinge mechanism. The hinge consists of several hardened and articulated cuticle elements called sclerites. This ...

The integrated navigation systems of Global Positioning Systems (GPS) and Inertial Navigation Systems (INS) are used to provide direct-georeferencing for Mobile Mapping Systems (MMS). MEMS (Micro Electro-Mechanical Systems) inertial sensors have been developed to the stage that the GPS/INS integration systems based on low-cost MEMS IMU (Inertial Measurement Unit) are considered to be used as a ...

This paper presents the design, modeling, analysis, and experimental results of a novel bipedal robotic system that utilizes two interconnected single degree-of-freedom (DOF) leg mechanisms to produce stable forward locomotion steering. The DOF is actuated via Reuleaux triangle cam-follower mechanism constant body height foot trajectory. Kinematic analysis dimension selection conducted first ge...

At present, the wheel loaders on market have steering vibration problems, which can be summarized as follows: front frame and cab vibrate violently at beginning end of steering. This paper analyzed mechanism by collecting pressure different positions hydraulic system AMESim simulation. A cushion valve was designed to solve problem vibration. Finally, prototype test carried out it concluded that...

Orbital steering is invoked to explain how the three-dimensional structure of a small self-cleaving RNA, the hammerhead ribozyme, both prevents and enhances RNA autocatalysis. Within the conserved catalytic core of the ribozyme, the position of the 2' oxygen atom of the G8 ribose is observed to be aligned almost perfectly with the phosphorus atom and the 5' oxygen atom of the adjacent A9 phosph...

Crawling mechanisms with energetic and control autonomy may move and steer by sliding on the ground. The paper presents an analytic and MBS simulation study on the possibilities and limits of steering a tetrahedral mechanism on a slope. The mechanism movement is analyzed using an equivalent 3d model. The analysis is structural, kinematical, static and dynamic. The limit conditions for stability...

Computational steering allows researchers to monitor and manage long running, resource intensive applications at runtime. Limited research has addressed high performance computational steering. High performance in computational steering is necessary for three reasons. First, a computational steering system must act intelligently at runtime in order to minimize its perturbation of the target app...

According to the independence, accuracy and controllability of the driving/braking torque of the distributed drive electric vehicle, a control strategy of differential drive assisted steering was designed. Firstly, the assisted curve under different speed and steering wheel torque was developed and the differential torques were distributed to the right and left front wheels. Then the steering r...
