There are times, when words feel too inadequate to express our deepest and most valued emotions and one thinks that, words will not do justice to the sensitivity of our feelings. That’s the time when we feel stumped and really frustrated, keeping such emotions bottled up inside.

Now, DIYer Wei-Chieh has devised an innovative way to ensure that, these emotions have to be expressed and that way is in the form of a tail. That’s right, a robotic tail that wags and mimics almost every gesture, as a real tail would do.

The highly innovative robotic tail is developed around the widely used Arduino technology and consists of an Radio Frequency Identification or RFID chip, that detects, understands and mimics the various emotions it designed to replicate, via emotions cards.

Here is a video of the Robotic Tail Wagging.
