Caia

Caia is a robot that fills your room with sunlight, and most interesting part is that it's sending the sun where you need it most in your room. You can place Caia anywhere you want and installation is not required at all. It will fill your room with sunshine. Just set it in a sunny spot inside or outside and point in the direction you want to make lighter. Caia will start its job. And you never need to plug it in or recharge as far as it’s solar-powered!

I think it's quite a good robot especially for developers and designers who work near the laptop and sits on Sofa which is far from the window. Such a robot can fill the whole room with sunlight and make you more productive to continue your work :)
A really good job was done by their team.
