Anyone with a plant in your home will know that most of them need both water and light to grow, but sometimes the problem is to find a sunny spot suitable for our plant. To solve this small problem, the Belgian sculptor Stephen Verstraete has created an interesting robot.
This robot, which seems not to be named, is responsible for transporting the plant automatically to a place with sunlight. The robot is made from a recycled toy electric car and you have placed a photo-sensitive transistor, a pair of ICs and some more goodies totaling approximately $ 10, which is certainly cheap enough.
If you want to build your own, I suggest you visit the site Verstraete.
