  1. 1. Superquadrics Augmented Rapidly-exploring Random Trees.

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : YARED EFREM AFEWORK; [2019]
    Keywords : Superquadrics; RRT; GJK; Collision Detection.; Superquadrics; RRT; GJK; Kollisionsdetektering.;

    Abstract : This thesis work investigated the advantages and disadvantages of using superquadrics (SQ) to do the collision-checking part of the Rapidly-exploring Random Trees (RRT) motion planning algorithm for higher Degree of Freedom (DoF) motion planning, comparing it with an established proximity querying method known as the Gilbert-Johnson-Keerthi (GJK) algorithm. In the RRT algorithm, collision detection is the main bottleneck, making this topic interesting to research. READ MORE

  2. 2. Development of a motion platform for the G1X radar

    University essay from KTH/Lättkonstruktioner; KTH/Lättkonstruktioner

    Author : Kevin Ankarsköld-Flück; Erik Wiskman; [2019]
    Keywords : ;

    Abstract : The Giraffe 1X is a mobile short range 3D radar from Saab used for example to detect threats and create protection in a ground based air defence system. It can also be used on naval platforms for air and surface surveillance. During the development of the radar, the system needs to be tested for both sea and mobile land applications. READ MORE

  3. 3. Container vessel maneuvering model in shallow waters and assessment of maneuvering coefficients through system identification

    University essay from KTH/Marina system

    Author : Christos Kostoulas; [2017]
    Keywords : maneuvering theory; container 4DOF maneuvering model; Son and Nomoto; shallow water effects; system identification; maneuvering coefficients; semi empirical equations for maneuvering;

    Abstract : A vessel operating in the real world has to overcome wind, waves and ocean currents. The result of all the above is a motion of 6 degrees of freedom (DOF). READ MORE

  4. 4. A high-accuracy wide-angle acoustic system for distance measurements and robot positioning

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Ivar Bergkvist; [2017]
    Keywords : Technology and Engineering;

    Abstract : Wide-angle distance measurements are needed for positioning with multilateration when there is no information about in which direction objects of interest are located. Several transmitters of varying kinds were evaluated in a data-driven way using a 6 DOF robot actuator. READ MORE

  5. 5. Realization of a serially-linked haptic device

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : Ramtin Massoumzadeh; [2017]
    Keywords : haptic device; spatial haptics; simulator; serially-linked; cable transmission; IMU; hall effect sensor; sensors; tandkirurgi; simulator; haptik; haptisk enhet; serielänkad;

    Abstract : Spatial haptic interfaces have existed for more than 20 years but have not been widespread despite promising applications. The few devices found in the market as of today are either considered costly, of higher quality and produced in smaller series or mass-produced and cheap, but of lower quality. READ MORE
