  1. 1. PTZ Camera Tampering Correction Using IMUs

    University essay from Lunds universitet/Institutionen för reglerteknik

    Author : Ludvig Hansson; Måns Lindeberg; [2022]
    Keywords : Technology and Engineering;

    Abstract : The Pan-Tilt-Zoom (PTZ) camera is a type of camera that covers large areas, up to 360°, in addition to zoom. Some of these cameras are susceptible to tampering, which means that an additional angle measurement feedback is necessary to detect such attempts. This thesis has evaluated the possibility of using MEMS-based IMUs to solve this problem. READ MORE

  2. 2. PreCro : A Pedestrian Crossing Robot

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

    Author : EBBA HEDBERG; LINNEA SUNDIN; [2020]
    Keywords : mechatronics; Pixy2; vision sensor; magnetic encoders; pedestrian crossing; mekatronik; Pixy2; bildsensor; magnetisk givare; övergångsställe;

    Abstract : For people who suffer from visual impairment, getting around in traffic can be a great struggle. The robot PeCro, short for Pedestrian Crossing, was created as an aid for these people to use at pedestrian crossings equipped with traffic lights. READ MORE

  3. 3. Multisensor fusion and control strategies for low cost hybrid stepper motor solutions

    University essay from Luleå tekniska universitet/Signaler och system

    Author : Mattias Wallin; [2017]
    Keywords : Multisensor fusion; Hybrid Stepper Motor; Extended Kalman Filter;

    Abstract : This thesis has explored if it is feasible to produce a good estimation of the rotational position of a stepper motor by using sensor fusion schemes to merge a sensorless position estimation (based on the back electromotive force) with the measurement from a magnetic rotational position sensor. The purpose was to find a cheaper alternative for position feedback in closed loop control from conventionally used rotational encoders and resolvers. READ MORE

  4. 4. Design and optimization of a signal converter for incremental encoders : A study about maximizing the boundary limits of quadrature pulse conversion

    University essay from KTH/Maskinkonstruktion (Inst.)

    Author : ANTON DAHLQVIST; Victor Karlsson; [2016]
    Keywords : ;

    Abstract : This project was carried out during spring 2016 in collaboration with BOSCH Rexroth, Mellansel, and aimed to investigate the possibility of implementing a converter with the ability to scale incremental pulse resolution and also convert the velocity to a 4-20mA current loop reference. An investigation on how a fault tolerance mechanism could be implemented to increase the dependability of the encoder was done and the out-coming results were implemented. READ MORE

  5. 5. Modeling, Identification and Control Design for an Electro-Hydraulic Rotator

    University essay from Linköpings universitet/Institutionen för systemteknik

    Author : Andrej Zanhar; [2010]
    Keywords : Hydraulically actuated system; Friction compensation; Cascade Control; Stereo Camera;

    Abstract : Robotic manipulators have been introduced in industry as a form of increasing productivity. Today, there exist an interest to enlarge the application of these manipulators to outdoor environments. Forestry cranes used in the forestry industry are a clear example. READ MORE
