As an amateur it can be difficult filming from several angles at the same time as this requires several cameras. It´s also hard to film at occasions when it´s not appropriate to manoeuvre the camera manually. Systems for solving these problems already exist, but it´s either more expensive, professionalsystems or cheaper systems with limited functionality.The purpose of this project is to develop a cost efficient solution to the problem above that offers a better functionality then existing commercial systems. The biggest difference from existing products is the wireless video feedback from the camera to the remote unit.The result of the project is a system consisting of two units, a manoeuvre unit with a cradle for the video camera and a remote unit from which the operator can control pan and tilt of the video camera.Communication between the two units is wireless.On the remote unit there is a joystick and a display mounted. In addition to this, there is also an IR receiver that is capable of reading the signal from the cameras own remote and sending it to the manoeuvre unit.The manoeuvre unit is equipped with one motor to control the tilt function and one motor to control the pan.

The task in this master thesis was to design and construct a prototype of a satellite antenna driver unit. The unit is to be robust and work in cold weather down to -40°C, so that it can be mounted on the roof of a minibus. A microcontroller controls the H-bridges simultaneous, each connected to an electrical motor. Hardware and software protections were implemented to ensure that the antenna can not turn outside its allowed area and risk breaking. The unit can output voltages at many different levels and communicate at a multitude of signal standards..

BAE Systems Hägglunds has a long history of producing high performance terrain tracked vehicles (mostly for military applications), and they are now aiming at developing a tracked forwarder with similar techniques.The forwarder will be of series hybrid type where a diesel engine via a generator will power the motors (one for each drive wheel). Thanks to individually controlled motors and the gentle rubber tracks, this forwarder is calculated to have a considerably higher average speed in the terrain and to be more gentle to the soil. The forwarder with a weight of 11 metric tons and a load capacity of 15 metric tons is specified to have an average working speed of 7-10 km/h, a top speed in terrain of 15 km/h and a top speed on roads of 40 km/h.This master?s thesis aims at developing a conceptual design of the forwarder?s drive module which includes electric motor, gear unit, brake and drive wheel.To investigate if the requirements can be fulfilled a study of the dimensioning loading scenarios has been carried out. The resulting needs regarding the torque has been considered in order to determine the required gear ratios for different motor options.

This report describes the design and construction of a prototype that automatically aims a microwave link towards a target. The link, that is located on a mobile aerial mast, is used by Saab Training Systems as a part of an infrastructure network. The report also discusses the development of a GUI that communicates with the control unit by Bluetooth.The control unit, called Pan/Tilt-controller, controls the position of the link by stepping motors. One motor controls the azimuth angle and the other one controls the elevation angle.By a GUI the operator enters the coordinates on its own position and the targets position. Hereafter a bearing is calculated and it will be sent up to the control unit.The control unit will sense its own direction by a magnetic sensor that works as an electronic compass.

AbstractMy purpose with this study is to find out if it helps children who have diffuculties with their concentration if they get to practise their motor behaviour knowledge during their day at the school to promote their learning capacity. My purpose is also to find out how schools works with motor behaviour training. To get answers to my questions have I done interviews with four educationalists and I have also used books and internet sites. Motor behaviour is of importance to how children learn things in the school, without a well working motor children gets difficulties to sit still and to concentrate. The children may put their energy at the wrong things in the classroom, when the energy instead should be need to learning things.

Gtherm is an innovation company who has an unique air heat exchanger underdevelopment. The purpose of this thesis is to provide data of suitable motors for theheat exchanger and to find suitable motor suppliers.A motor specification was designed. It is an important basis for the search of suitablemotors. A compilation was made of nine motor suppliers and the suitable motorsfrom those. The compilation can be used by GTherm in their choice of suppliers andmotors.The compilation of the demands on the motor and analysis of suppliers indicated thatthere were no standard motors available to GTherms air heat exchanger.

AimThe aim with this essay has been to investigate how preschools profiling in motor activity training, work to stimulate motor development of children. In order to study this, the main focus for the research has been on the following queries:What characterize motor activity training at the preschools studied?What is the purpose with the motor activity training of preschools which were studied?How do the preschools describe the affect that motor activity training has on children?How do the preschools look at the need for motor activity training?MethodFour in-depth interviews were conducted with representatives of the chosen preschools profiling in motor activity. My selection was based on a strategic sample and this was made by an internet mapping of preschool activities in the districts of Stockholm, and information from the service guide of the town of Stockholm. Then e-mail was sent to ten contact persons at preschool units, and ten preschools were contacted directly by phone.

AbstractThis work is about children?s motor activity. You can often hear in media about sedentary children, and that one of the factors which contributed to this is computers and things like that. The main goal with this work is to find out how preschool teachers take care of children?s joy of movement and how they work to promote children?s progress of motor activity.

This thesis work contains a litterature study about electrical motors in general and how PWM-patterns for brushless DC-motors can be made. A suitable method has been implemented as a simulation model in VHDL. A simulation model of a brushless DC-motor which describes the phasecurrents, torque and angular velocity has also been made. The motor model made simulations easier for the complete PWM-system. The design was synthesised and tested with a prototypeboard including a SPARTAN II FPGA.

In everyday life we perform motor behaviours that have no apparent instrumental function. Are these correlated to sensation seeking and do they differ depending on what situations we are in? University students in Örebro (N=108), participated in the study. The participants were asked to fill out a double questionnaire containing the sensation seeking scale and another one for measuring non-productive motor behaviours. The non-productive motor behaviours were not correlated to the sensation seeking scale.

The intention of the study is to investigate pedagogues understanding of physical activities in preschool. Should special activities be planned in order to stimulate children´s progress in motor skills? I also want to find out if pedagogues found the acitivities in preschool curriculum which says that the aim is to develop children´s body perception and teaching children how to care for their own health. I have interviewed seven pedagogues and focus of the question lied within motor skills and the joy of movement among preschool children. The result shows that pedagogues regard it to be important to stimulate motor activities and to encourage joy of movement in preschool.

In the electronic industrials, power control of AC motors is commonly used. For example power control of a washing machine motor, a vacuum cleaner motor or a coffee machine motor. The company Rejlers Ingenjörer AB has many projects where power control of AC motors is included. A prototype card for this task can save time and money for the company in the future and this is the reason for this thesis.The motors are power controlled by a TRIAC and control of the trigging pulses to the TRIAC. This card is modularly built and can easily be adapted for future projects where the power control of AC motors are included.The prototype card can be used as a subsystem in a larger electronics projects or as it is in lab environment for testing and evaluating new motors..

However, the testing has been done at a high level. In order to continue to evolve, the group that develops Palasso has started to look at the new development methods that have become popular in the computer industry in recent years.

On some occasions it may be inappropriate with a cameraman behind the camera. In somecases there is no cameraman available or it is a smaller event, like a family celebration, to befilmed. It can also be difficult for a cameraman to shoot from certain angles. One solution forthis kind of situations can be to remotely control the camera movements. There are thosekinds of solutions on the market today but they either address professional filmmakers or thefunctionality is limited, for example by the absence of wireless remote control.This project aims to develop a solution to the problem with absence of wireless remote controland also a solution with more flexibility and less complexity than today?s solutions.

Humans and dogs are both mammals. One of the differences between the two species is that man walk on two legs and dogs on four legs. There are also differences in the nerve system between the two species. The human nerve system is supposed to provide opportunity for fine motor tasks- while the nerve system of the dog is more focused on the ability to perform locomotor tasks. Humans need to increase their motor control and postural control when affected by various conditions and diseases.
