To survive in this world, all plants need some basic things like air, sunlight and water. If you want to keep plants in your house then there is an issue and that is sunlight. Air and water are not a problem, they are always available. Stephen Verstraete, the Belgian sculptor gave a perfect solution to solve this issue. Verstraete developed a robot that looks for sunlight after the plant is placed on it. It gathers an adequate amount of sunlight for the houseplant.
This is simply amazing for a plant lover. For his experiment, he installed a photo transistor (light sensitive); some ICs and some important devices need for making a robot in a recycled toy car. You can’t believe the expense for the total development was just $10. Not only that, they are also trying to minimize this cost.
The court placed on a wheeled platform and its collision switches are applied to helping the robot to avoid stuck. If you are interested in it, then you can get information from internet. Verstraete provides all details like list of parts, total circuit layout etc. for the people who are interested in this robot. In my sense, it can be a great choice for your houseplants.
