Sometimes the technology part of a project isn’t the hard part. It is having an idea for something both useful and doable. Sure, a robot butler that would do your cleaning and laundry would be useful, but might be out of reach for most of us. On the other hand, there’s only so many use cases for another blinking LED.
[Martinhui] knows how to use an ultrasonic sensor with an Arduino. Driving a motor isn’t that hard, either. The question is: what do you do with that? [Martin’s] answer: Automate a trash can. You can see a video of the result, below.
You can find commercial versions of this, of course, but what fun is that? The can is a bit small, but a larger motor or a different mechanical design could scale it up easily.
As robotic trash cans go, this isn’t that ambitious, but it is highly doable. If only it connected to the Internet.
