[0002] Laboratory animals are indispensable tools in life science research. They refer to animals that have been artificially bred, whose microorganisms are strictly controlled, and whose genetic background is clearly defined. Common examples include mice and rats, which are highly prolific and inexpensive, and are widely used in drug development and gene research. Other animals, such as rabbits, dogs, and miniature pigs, are often used in medical experiments due to their physiological similarities to humans. They provide crucial support for medical breakthroughs, drug safety, and the development of biological sciences, driving progress in human health.

[0003] In laboratory animal husbandry, cages are commonly used. To ensure the healthy growth of the mice, waste collection and disinfection within the cages are necessary. Currently, waste collection and disposal mainly rely on manual cleaning by staff, which is not only labor-intensive and time-consuming, but also inefficient. Furthermore, human error can easily lead to omissions, affecting the thoroughness of cage cleaning. Prolonged exposure to such an environment makes the mice susceptible to bacterial and viral growth, impacting their health and interfering with the accuracy of experimental results. Additionally, staff may be exposed to harmful microorganisms, posing occupational health risks. Therefore, we propose an automated waste collection and disinfection device for laboratory animals.
