It used to be that your options for an interactive robotic friend was limited to either Teddy Ruxpin or a Furby. Now, we have much cooler options available, like the Little Robot Friends on Kickstarter.
Even without a bunch of fake fur, these little bots are charming. They have some Tamagotchi-like characteristics in that they change and adapt as you interact with them. They can also interact with each other.
Each robot comes with a different personality, but can change over time. For example, a timid robot can be encouraged by petting its hair. Eventually, it will develop to come out of its shell and be more confident in its beep-and-boop interactions.
Each Arduino-controlled bot is made with LED eyes, a small speaker mouth, a microphone, an ambient light sensor, and touch-sensitive "hair." Two AAA batteries provide the power.
Though some of the pledge levels are sold out, you can still get a Little Robot Friend fully assembled and customized to your specifications for about $50. You can even set the parameters for its initial personality. If you're into coding, the little bots are simple to hack into when you choose a package that includes a developer dock.
If you've outgrown Tamagotchi and are annoyed by Furby, but still want a cute robot companion, then Little Robot Friends could be the droids you're looking for.
