Sure, you can get small, robotic lawnmowing robots that zip along the ground giving your grass the trim it needs, but somehow that just doesn't feel satisfying. For one, it doesn't look like a lawnmower. That adjustment is just too difficult to make. Without someone pushing it, how do I know it's working?

Ah, here we are. The Dynamizer is a little robot that pushes a tiny mower around. It walks behind it, not relying on wheels or some other lazy device to get its job done. It even pauses to wipe its brow. Aw, it thinks it's people! And that's just the sort of thing you need to see to feel like your former labor is being taken on properly. Thanks, Dynamizer!
