Say hello to Ken Lim's "Guardian Robot," which will keep an eye on your Twitter feed for happy or sad messages from your friends, raising its arm in triumph or lowering its head sulkily. While it may not look like much (though it's still got an undeniable charm to it), the Guardian has a neat quirk: if it's happy, a high-five to its raised arm returns it to its idle state. Along the same lines, a "hug" to its belly will stop it from being sad.

Your friends won't get any of the love, but maybe it'll remind you to send them some. Well, unless you hit up Guardian Robot at its Twitter account. Then it'll high five or hug you all you want. Check out a video of the Guardian Robot down below.
