Poka: A Necro‐Robot Beetle with a Measured Payload Ratio of 6847%

Advanced Robotics Research, EarlyView.
Here, Poka, a necro‐robot beetle with the ability to carry more than 68 times its own weight, is introduced, making it also a walking robot with the highest payload ratio measured to date. This paper is concerned with the design, manufacture and validation of ‘Poka', a novel millimetre‐scale necro‐robot aimed at bridging the performance gap between ...

Insect-Foundation: A Foundation Model and Large Multimodal Dataset for Vision-Language Insect Understanding [PDF]

arXiv
Multimodal conversational generative AI has shown impressive capabilities in various vision and language understanding through learning massive text-image data. However, current conversational models still lack knowledge about visual insects since they are often trained on the general knowledge of vision-language data.

Insects in fluctuating thermal environments.

Annual Review of Entomology, 2015
All climate change scenarios predict an increase in both global temperature means and the magnitude of seasonal and diel temperature variation. The nonlinear relationship between temperature and biological processes means that fluctuating temperatures ...

How forest insect outbreaks depend on forest size and tree distribution: an individual-based model results [PDF]

arXiv
In this work, an individual-based model of forest insect outbreaks is presented. The results obtained show that the outbreak is an emerging feature of the system. It is a common product of the characteristics of insects, the environment in which the insects live, and the way insects behave in it. The outbreak dynamics is an effect of scale.
