The article discusses the evolution of robot vacuum cleaners, particularly highlighting how older models such as the Roomba can be creatively repurposed. A notable example is the 'Space Vacuum,' which has been modified with Arduino and NASA software to detect dogs and dispense food rather than clean. This mod showcases the potential of repurposing outdated technology for new, fun functions, countering the typical fate of electronics becoming obsolete and collecting dust.
What the Space Vacuum basically does is detect the presence of a dog, while differentiating it from other living critters in the house, and drops dog food from a paper cup that has its bottom partially cut out.
This Roomba, for example, once cleaned up dirty floors in a previous lifetime. But with some clever use of off-the-shelf hardware... it has been given a new lease on life as a dog food dispenser.
