title: Extended Kalman Filter SLAM Implementation for a Differential Robot with LiDAR

authors: Abdel Qader, Hisham Fawzi Fayez

subjects: SLAM

abstract: SLAM is an approach deployed in robotics to develop autonomous mobile robots. These robots have been deployed in numerous fields such as manufacturing, aerospace navigation, and other areas deemed dangerous to humans. SLAM techniques have made these robots to operate without necessarily having the prior maps, a shortcoming of the current robots which require prior maps. Several SLAM approaches exist, but EKF has been seen to possess all the useful features of convergence and consistency. Via SLAM, concurrency between localisation and mapping has been made possible.
An EKF SLAM algorithm has been presented in this thesis, which was implemented in a two-wheeled mobile robot. The robot autonomously navigated in a structured indoor environment, while simultaneously building a map and localising itself within that map. A 360 degrees LiDAR was used to measure the range and bearing of the surroundings and an ultrasound sensor was used to avoid the obstacles. Furthermore, the algorithm was implemented using Python 3.

title: The developing field of technology education: a review to look forward

authors: Jones, Alister

abstract: This paper attempts to review the development of technology education over the last 20–25 years. The purpose is to reflect on how far the field has come and where it might go to, including what questions need to be considered in its ongoing development. The data for this paper draw on our work in developing The International Handbook of Research and Development in Technology Education (Jones and de Vries 2009). However, the paper is more than a summary of this work, instead representing a synthesis in its own right. The work was not undertaken to report solely on the collective achievement of a large number of people internationally, but rather to use this as a means for setting a sound foundation for future research, development and teaching in technology education. By considering the underlying philosophy, international development of curriculum, relationships of technology education with other subject areas, teaching, learning and assessment as well as teacher education, and educational research, we are able to scope past activities and present an agenda for moving forward in teaching, research and development.

title: Kia reo Māori anahe te reo karanga

authors: Puke, Haupai

subjects: Karanga

abstract: Mā taku karanga o runga ake nei tēnei tuhinga e wāwāhi. Ahakoa he aha te ahurea ōna tikanga me ōna kawa, kua hurihia i roto i ngā rautau. Ko ngētehi kei te pupuruhia tonutia hāunga anō he hou ōna āhuatanga. Ko te kaupapa rangahau o tēnei tuhinga ko te karanga me ngētehi āhuatanga ōna hei tautoko i te whakahau kia noho reo Māori anahe te reo karanga. He aha e pēnei na ai te whakaaro mō tēnei o ngā tikanga o te ao Māori? I runga anō i ngā āhuatanga hou, i ngā whakarerekētanga tikanga o te karanga i roto i tēnei ao hurihuri kāore e tautāwhina te take. Ko ngā kōrero, ngā whakaaro hoki e whai ake nei e wānangahia ai hei tautoko i tēnei whakapae āku.
