There’s no need to mention that how we are dependent on plants. These green leafy friends of ours provide us with oxygen, food and so many other things that we can just be grateful to have such a company. This sapling has not grown out from a seed but still is very friendly. How?

It has a great quality of being a good listener. Now what does that mean? Actually this is a robotic plant with a system that reacts to your speaking. You just have to talk to it and it listens and responds. You need not even provide it water or keep it in sunlight, it will  just be happy to nod at whatever you have to say. Not only that it has several ways of nodding ability and has different reaction ways for different voice tones of yours.

This is the Sega Pekoppa Robot Plant from Japan which uses muscle wires for the fluid movement. It is based on “Unazuki riron” ( the nodding theory).
