Konferensbidrag (refereegranskat)abstract
- This article presents a novel emotionally expressive robot platform targeting social engagement with children. This platform was implemented in accordance with UNICEF's policy guidance on artificial intelligence (AI) for children, focusing on factors such as safety, transparency, reliability and explainability. The robot prototype is presented from a design and development perspective, outlining all utilized electromechanical components that enable its 11 degrees-of-freedom and sensing functions. Preliminary evaluation results are provided in terms of dependability and expressiveness of basic emotions, thus demonstrating the robot's potential to facilitate trustworthy and secure interactions with children.

Tidskriftsartikel (refereegranskat)abstract
- Presently there is an opportunity to promote organic farming in the Central and Eastern European Countries (CEEC) that joined the EU in 2004. The development of organic farming has the potential to decrease the amount of nutrient leaching to the Baltic Sea and could help to stop the environmental degradation of the Sea. However, this requires a diverse set of institutions. This paper explores the institutions that are lacking to promote full development of organic farming in the CEEC. A case study approach, formalised by introducing a set of indicators, has been used to identify the missing institutions. Data has been obtained from a desktop study, including a literature review, interviews and a questionnaire. The case studies partially support previous studies proposing that the development of organic farming proceeds along six steps: development of an organic farming community; development of the political recognition; establishment of financial support; establishment of non-competitive relationships between the organic sector and general agricultural institutions; development of a domestic organic food market; and development of a discussion and coordination arena. The results show that market development is the least developed step.

- A window of opportunity to promote organic farming is open for the Central andEastern European Countries (CEEC) that joined the EU in 2004. The development oforganic farming has the potential to decrease the amount of nutrient leaching tothe Baltic Sea and could help to stop the environmental degradation of the Sea.However, this requires a diverse set of institutions. This paper explores theinstitutions that are lacking to promote the full development of organic farming inthe CEEC, using Sweden as a baseline reference. A case study approach, formalisedby introducing a set of indicators, has been used to identify the missing institutions.Data have been obtained from a desktop study, including a literature review,interviews and a questionnaire. The case studies partially support previous studiesproposing that the development of organic farming proceeds along six steps:establishment of an organic farming community; establishment of politicalrecognition; establishment of financial support; establishment of non-competitiverelationships between the organic sector and general agricultural institutions;establishment of an organic food market; and development of a discussion andcoordination arena. The results show that market development is the leastdeveloped step and that there is a correlation between higher governmentalengagement and a more developed organic sector.

Development of an Emotionally Expressive Robot Platform
- 2023

Annan publikation (övrigt vetenskapligt/konstnärligt)abstract
- This project was set to focus on developing a social robot for child interaction.The goal was to create a tabletop robot that, through nonverbal communication, was able to express the six basic emotions of anger, disgust, fear, happiness, sadness and surprise. It should do so whilst providing a safe, transparent, explainable and accountable interaction, complying with UNICEFs policy guidelines on AI for children. Haru, the social robot project led by Honda Research Institute of Japan, was used as the main source inspiration. To start of the project, a state of the art analysis was performed, where several fields of study and existing social robots were investigated. From here, three concepts were derived: Improved Haru, the Egg, and the Snowman. Trough evaluation, the Egg was deemed the best candidate for further development. After an iterative second design process, a final solution was reached. The report examines the final mechanical and electrical design as well as the software in use in more detail. The dimensions of the robot are 28 cm in height (in its closed state) and 20 cm in base diameter. The total cost of the robot is 918 €. Validation through questionnaires, a reliability test as well as a noise test were performed. The results indicate that colours and graphics help the user to perceive the emotions more accurately. Angry, sad and shy were the emotions with the highest correct-perception-rate whilst happy, surprised and disgust had the lowest. The robot’s reliability showed great potential as no component reached temperatures worthy of concern. However, one of the motors got a recurring failure. The maximum equivalent noise level was 46 dBA, measured at 1 meter away from the robot. It was deemed that the robot met most of the stipulated requirements. Some of the future work suggested are improved mechanics, design and motion control, minor changes in electronics, the implementation of FSM as well as the expansion of explainability and user interaction.

Forskningsöversikt (populärvet., debatt m.m.)abstract
- Miljöproblemen i Östersjön är allvarliga, och kunskapen om exakt vilka risker de innebär är omdebatterad. I ett forskningsprojekt har vi kartlagt hur miljöriskerna bedöms och hanteras idag, och konstaterar att det finns ett behov av att den traditionella riskbedömningen kompletteras med ett större mått av försiktighet och ett ökat deltagande av samhällets olika aktörer.
