Gyroscopic Stabilization of Two Wheeled Electric Vehicle

This paper report on research and fabrication of an electric vehicle prototype that will be capable of balancing itself without human effort. This vehicle will be implementing a control moment gyroscope for balancing purpose. The project also concerned about the environmental effects of conventional internal combustion Engines and to effectively use the alternative propulsion system which is electric traction system, where using Electric motors the vehicle is propelled. The system uses a control moment gyroscope to static balancing of the vehicle and using its angular momentum and precessional moment. Along with the fact that it uses a electric traction motor he implementation of new optimizations for power and mileage the efficiency is improved.

Design and architecture solutions for service robot waiter with a specialized system of payload stabilization

Application of robotic devices in subject domains, where monotonous routines have to be performed promptly and accurately, is a relevant problem, particularly in complicated epidemiological situations. In this paper the design of robot waiters is analyzed and a design is proposed for stabilization of payload during delivering. Common applied problems in the robotic service domain are associated with the need to use such robots on mostly even, flat surfaces or with the arrangement of special structures that simplify the movement of a robotic device along a given route. The proposed solution potentially provides for cheaper, simpler and more optimized application of the robotic device indoors, inside the restraunt due to the developed buffer mechanism and the system of gyroscopic stabilization of the trays, as well as the implemented control system based on the PID controller and the PWM generator, which ensures the smooth movement of the robot (from the starting point to the destination point). Based on the proposed solution, we get a fully functional robotic device that does not require additional investments in the reconstruction of the restaurant premises, completely replaces the waiter when delivering food and drinks to the client's table, and also attracts new customers due to its novelty and practicality.

Closeup exploration of the seafloor with an autonomous underwater helicopter

Closeup exploration of the seafloor requires new forms of underwater vehicles that are capable of taking off and landing on the seafloor and hovering at any attitude and that are equipped with cameras and sensors. Existing underwater vehicles do not provide an adequate platform for closeup in situ observations. This work presents the design, fabrication, control and testing of an autonomous underwater helicopter (AUH) that can perform spin turns, vertical rotation, free landing and take-off, making it the most agile underwater vehicle to date. Acoustic-optical navigation and gyroscopic stabilization systems were implemented to complete missions on a fixed route. With an underwater base station(helipad), the AUH can perform wireless power charging and data transmission. This work builds on previous generations of AUHs that were restricted to horizontal postures and lacked vectoring propulsion. Experimental results gathered from tests show that the AUH can successfully navigate along a preset route at depths ranging from 0 to 100 metres. Furthermore, with multidimensional attitude adjustment and vectoring propulsion, AUH is capable of diving into a rugged seafloor environment. This study advances what is currently achievable using traditional AUVs and ROVs, demonstrating methods that can be used in the future for studying marine science and seafloor exploration.

Induction Suspension of Conductive Microring and Its Gyroscopic Stabilization

The main task of our work is determination of possible levitation of micro-ring with eddy current in magnetic field of down ring with set alternating current and determination of critical value of «ohmic» damping separated field of parameters, at which motions of suspension ring transit from divergent to meeting to steady-state equilibrium position. I. e. in this critical case the motion practically coincides with motions of conservative system. The possibility of gyroscopic stabilization of suspension ring taking into account initial set rotation is considered. Thereby it can serve as contactless micro-gyroscope.

Analysis of a Gyroscopic-Stabilized Floating Offshore Hybrid Wind-Wave Platform

The energy innovation scenario sees hybrid wind-wave platforms as a promising technology for reducing the variability of the power output and for the minimization of the cost of offshore marine renewable installations. This article presents a model that describes the installation of a 5 MW wind turbine on a floating platform designed by Fincantieri and equipped with gyroscopic stabilization. The use of gyros allows for the delivery of platform stabilization by damping the wave and wind induced motion on the floater and at the same time producing extra power. Shetland Island was chosen as the reference site because of its particularly harsh weather. Final results show that the total production of power in moderate and medium climate conditions is considerable thanks to the installation of the gyro, together with a significant stabilization of the platform in terms of pitching angle and nacelle acceleration.

Gyroscopic stabilization minimizes drag on Ruellia ciliatiflora seeds

Fruits of Ruellia ciliatiflora (Acanthaceae) explosively launch small (2.5 mm diameter × 0.46 mm thick), disc-shaped seeds at velocities over 15 m s −1 , reaching distances of up to 7 m. Through high-speed video analysis, we observe that seeds fly with extraordinary backspin of up to 1660 Hz. By modelling the seeds as spinning discs, we show that flying with backspin is stable against gyroscopic precession. This stable backspin orientation minimizes the frontal area during flight, decreasing drag force on the seeds and thus increasing dispersal distance. From high-speed video of the seeds' flight, we experimentally determine drag forces that are 40% less than those calculated for a sphere of the same volume and density. This reduces the energy costs for seed dispersal by up to a factor of five.
