Electronic Speed Controller Based Quad Copter Controlled by Hand Gestures

To control a Quad copter by means of simply the use of hand gestures.It allows us to recommend a way to perform Human computer Interface.The concept is to extract an antique techniques of controlling a Quad copter using joysticks, computer controlled and so on.with more intuitive approach, that is, through controlling the Quad copter with the assist of hand gestures, for the user to make it greater user friendly,this makes the user not to study different instructions to control a Quad copter, where it can simply work on the hand gestures. Here we present an approach to achieve the illustrated idea by employing transmission of instruction through a Bluetooth module. A simple gyroscope helps inhelps in tracking hand gesture illustration. Command dedication corresponding to shown gestures and acting movement respectively.

Improvement of angular velocity and position estimation in gyro‐free inertial navigation based on vision aid equipment

In conventional navigation systems, inertial sensors consist of accelerometers and gyroscopes. These sensors suffer from in‐built errors, accumulated drift and high‐level noise sensitivity. The accurate gyroscopes are expensive and not suitable in cost‐effective applications. To minimise such disadvantages, one solution is the combination of inertial sensors with different aiding sensors. To lower the cost, utilisation of redundant accelerometer structure as gyro‐free inertial measurement unit (GFIMU) has been proposed. In this study, Gyro‐Free navigation errors using four tri‐axial accelerometers are illustrated. Compensation of errors in terms of angular velocity and position estimation is verified based on adding a simple gyroscope, inexpensive stereo cameras as well as creating an easy to use topological map. The topological map is easily created by means of scale‐invariant feature transform method. The estimation of angular velocity is corrected on the basis of fusing the measurements from GFIMU and a simple gyroscope using unscented Kalman filter. The correction of position is performed by comparing the estimated position from GFIMU and observation of stereo cameras together with topological map. The results of the research show that the collaboration of GFIMU, stereo cameras and simple gyroscope will improve the robustness and accuracy of navigation, significantly.

A Joint-Angle Estimation Method for Industrial Manipulators Using Inertial Sensors

This paper focuses on the use of low-cost inertial sensors in industrial manipulators. In particular, an easy-to-install joint-angle estimation method is proposed. This scheme can work independently from the primary encoder-based sensor, for the creation of a fault-detection system. It can also be the primary joint-angle sensor in low-cost robotic manipulators. A robot with six degrees of freedom has been used, with three inertial measurement units set on its arms; one for each pair of joints. Three cascaded extended Kalman filters have been used to estimate the joint angles by the fusion of the outputs of triaxial gyroscopes and accelerometers. The results of three experimental tests are reported in order to show the performance and limitations of this approach, in comparison with the simple gyroscope measurements integration.

The gyroscopic properties of water

The fundamental principles of a simple gyroscope can be applied to the motions of molecules.

Elementary Analysis of the Gyroscope

The simple gyroscope is an excellent subject for a lecture table demonstration to classes in elementary physics. The only observable force acting upon the precessing top is a downward pull due to gravity, yet, instead of falling, it moves with a continuous horizontal displacement. An adequate and convincing explanation of this curious behavior is essential, and it must be stated in language familiar to the student. One possible approach to the problem, using a very simple model, is given here. The internal reactions are described and their values are computed. Because of some difficulty in visualizing motion in three dimensions, it is recommended that a model be constructed. It may be very crude and yet quite adequate.
