  1. 1. On Optimal Lateral Tracking Control for Multi-Steered Autonomous Vehicles

    University essay from KTH/Optimeringslära och systemteori

    Author : Axel Strömberg; [2021]
    Keywords : Autonomous vehicles; path tracking; lateral control; preview control; vehicle motion control; Autonoma fordon; banföljande; lateral kontroll; kontroll genom förhandsgranskning; kontroll av fordonsdynamik;

    Abstract : The transport industry is experiencing a disruption as fully autonomous vehicles are introduced in traffic. The intelligent, driverless vehicles will reduce cost, liberate human effort and increase safety. READ MORE

  3. 2. Planetary Rover Wheel and Lower Leg Structural Design to Reduce Rock Entanglements

    University essay from Luleå tekniska universitet/Institutionen för system- och rymdteknik

    Author : Natalie Lawton; [2020]
    Keywords : Mars; rover; wheels; planetary rover wheels; flexible wheels; rigid wheels;

    Abstract : This thesis looks at the SherpaTT planetary rover. The rover is a hybrid walking and driving rover that has been developed and built by DFKI and has already been deployed on several Mars analogue field studies. The SherpaTT rover wheels were found to become entangled in rocks during the last field deployment in Morocco. READ MORE

  4. 3. Dynamic simulation of a planetary gear for robots

    University essay from Linnéuniversitetet/Institutionen för maskinteknik (MT)

    Author : Xiaohao Qin; Jiahao Cheng; [2019]
    Keywords : dynamic simualtion; robots; PGT; solidworks; MATLAB;

    Abstract : Gear drives are widely applied in mechanical transmission systems and very accurate transmission systems are needed. In the robot industry, the planetary gear train (PGT) is commonly used to promote the torque transmission. One of the advantages of an ideal PGT is that the incoming torque is divided equally among the planet gear wheels. READ MORE

  5. 4. A Weak Formulation of Constraints to Couple Rigid and Elastic Bodies - a Study with FEniCS

    University essay from Lunds universitet/Matematik LTH

    Author : Axel Södersten; [2018]
    Keywords : Flexible multibody dynamics; differential-algebraic equations; interconnecting rigid joints; Mathematics and Statistics; Technology and Engineering;

    Abstract : Many complex mechanical systems are simplified by considering them as multibody systems. In recent years, flexible multibody dynamics has become more and more in demand. READ MORE

  6. 5. Motion Planning and Stabilization for a Reversing Truck and Trailer System

    University essay from Linköpings universitet/Reglerteknik; Linköpings universitet/Tekniska fakulteten

    Author : Oskar Ljungqvist; [2015]
    Keywords : Truck and trailer; general 2-trailer; modeling; gain scheduling; LQ; Pure pursuit; motion planning; RRT; CL-RRT;

    Abstract : This thesis work contains a stabilization and a motion planning strategy for a truck and trailer system. A dynamical model for a general 2-trailer with two rigid free joints and a kingpin hitching has been derived based on previous work. READ MORE
