  1. 21. A force control based strategy for extrinsic in-hand object manipulation through prehensile-pushing primitives

    University essay from KTH/Robotik, perception och lärande, RPL

    Author : José Iglesias; [2017]
    Keywords : Force-control; object manipulation; extrinsic manipulation; estimation; prehensile-pushing; grasp;

    Abstract : Object manipulation is a complex task for robots. It often implies a compromise between the degrees-of-freedom of hand and its fingers have (dexterity) and its cost and complexity in terms of control. READ MORE

  3. 22. Estimation of wheel-rail friction at vehicle certification measurements

    University essay from KTH/Spårfordon

    Author : Márton Pálinkó; [2016]
    Keywords : ;

    Abstract : In certification of new rail vehicles with respect to running characteristics, a wide variety of operating conditions needs to be considered. Behaviour on straight and curved tracks, including twisted tracks at various speeds, is of great importance. However, the wheel-rail friction should always be high corresponding to dry conditions.

  4. 23. An on-engine twin-scroll turbine performance estimation

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Viktor Olsson; [2015]
    Keywords : ;

    Abstract : In this study the main objective was to estimate the instantaneous turbine shaft power and turbine efficiency of a turbocharger mounted on a 6-cylinder 13 literheavy-duty diesel engine. The work was carried out at Scania CV AB in Södertälje, Sweden from January to June 2015 as master thesis under the division of Internal Combustion Engines at the Royal Institute of Technology KTH, Stockholm, Sweden.

  5. 24. Tire/road friction estimation for front wheel driven vehicle

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Simon Johansson; Viking Persson; [2015]
    Keywords : Technology and Engineering;

    Abstract : Vehicles of today are equipped with several driving enhancing systems. The Electronic Stability Program (ESP) controls the brakes of the vehicle to prevent undesirable vehicle behavior. The Anti-lock Braking System (ABS) prevents the wheels to lock up while braking hard. READ MORE

  6. 25. Innovative Gyroless Attitude Estimation Method

    University essay from KTH/Mekanik

    Author : Paul Dermarkar; [2013]
    Keywords : ;

    Abstract : A key aspect in Attitude and Orbital Control Systems (AOCS) is the ability to estimateaccurately a spacecraft’s attitude and angular rate. While a classic gyrometer and star-trackerhybridization features high performances, gyroless solutions using only star-trackers as attitudesensors are often chosen to reduce the mission’s cost, when possible.
