    ChatGPT for Robotics: Design Principles and Model Abilities

    Full text link
    This paper presents an experimental study regarding the use of OpenAI's ChatGPT for robotics applications. We outline a strategy that combines design principles for prompt engineering and the creation of a high-level function library which allows ChatGPT to adapt to different robotics tasks, simulators, and form factors. We focus our evaluations on the effectiveness of different prompt engineering techniques and dialog strategies towards the execution of various types of robotics tasks. We explore ChatGPT's ability to use free-form dialog, parse XML tags, and to synthesize code, in addition to the use of task-specific prompting functions and closed-loop reasoning through dialogues. Our study encompasses a range of tasks within the robotics domain, from basic logical, geometrical, and mathematical reasoning all the way to complex domains such as aerial navigation, manipulation, and embodied agents. We show that ChatGPT can be effective at solving several of such tasks, while allowing users to interact with it primarily via natural language instructions. In addition to these studies, we introduce an open-sourced research tool called PromptCraft, which contains a platform where researchers can collaboratively upload and vote on examples of good prompting schemes for robotics applications, as well as a sample robotics simulator with ChatGPT integration, making it easier for users to get started with using ChatGPT for robotics

    Micronucleus test and comet assay in erythrocytes of the Amazonian electric fish Apteronotus bonapartii exposed to benzene

    In this study we address the genotoxicity and putative mutagenic effects of benzene (BZN) in the erythrocytes of the electric fish Apteronotus bonapartii (Gymnotiformes, Apteronotidae) using the micronucleus test (MN) and comet assay, under controlled laboratory conditions. Electric fish were collected in the Solimões River, Manaus-AM, Brazil, and the specimens were exposed to 10 and 25 ppm concentrations of BZN, in 150L tanks. Blood samples were collected at 0 (T0), 24, 48, 72 and 96 hours of exposure. For the concentration of 10 ppm BZN, the number of comets was significantly higher than T0 levels after exposure of 48 hours, whereas the nuclear abnormalities (including MN) did not show any increase in relation to the controls (T0) up to 96 hours. For the 25 ppm BZN, MN rates presented a significant increase after 72 hours, whereas other types of nuclear abnormalities increased in frequency after various exposure times, ranging from 24 to 72 hours. The number of comets increased significantly from 24 hours onwards for 25 ppm BZN. Both assays also showed a gradual increase in the number of damaged cells after longer exposure periods, indicating a time-dependent effect, especially at the highest BZN concentrations tested. This investigation reinforces the potential use of the endemic South American electric fish as a suitable genotoxicity biological model for biomonitoring purposes in the Amazon.

    Consultation in land and marine planning : understanding methods and public opinion

    Get PDF
    This study explores the topic of consultation within the context of land and marine planning. Historically, participation developed within land and marine planning as a way of building trust with the public and as a result of bottom-up and top-down drivers. Previous research has shown consultation faces multiple challenges, including consultation fatigue and ‘tick-box’ consultations. Using Orkney as a case study, public opinions to consultation are examined and compared to the wider literature. An in-depth examination of opinions towards the Community Voice Method as part of the Scottish Wildlife Trust’s Oceans of Value Project explores how new, creative consultation methods might work in the Orkney context. This research was driven by the need for further research into public opinions around consultations. Findings show that opinions towards consultation are mixed. Evidence exists that genuine consultation and community engagement occurs in Orkney, but wider challenges persist. The issues highlighted within Orkney can be applied across Scotland. This research is relevant for designing engagement in future Regional Marine Plans, such as in Orkney. Possible improvements to the consultation process based on public opinions are suggested. The importance of using a range of methods is emphasised alongside understanding the local context when conducting consultation
