What’s better than a regular trash can? One that can take the trash out without you having to do anything. colinfurze’s RC wheelie bin is not there just yet, but it does let you remote control it. It has two motors, two batteries, and a joystick mechanism.
In a perfect world, such a trash can would be smart enough to avoid obstacles and know your schedule. You will have to wait for a while before such a smart trash can is available for sale though.
