Based in Seattle, Washington, Kickstarter entrepreneurs Peter Seid & Phu Nguyen (Romotive) have created a cute, playful robot that uses your smartphone as its brains. Dubbed Romo, the robot features a motorized acrylic base with tank-like wheels that offer maximum mobility. Inside the base is basic analog circuitry that controls the robot using programmed frequencies.
As you can see from the video above, Romo comes along with several different apps and is open for further development. Since the robot is controlled via a 3.5mm audio input, any smartphone that is capable of emitting the right frequencies can be used with Romo. As far as battery power goes, Romo utilizes a lithium-ion battery that comes with a USB charger.
Romo began as an ambitious Kickstarter project hoping to raise $32,000 in funding in order to create the first production batch, but with over 30 days still left in their campaign, Romotive has already raised over $45,000. If you're looking to get your hands on one of these cute creatures, all you have to do is contribute $78 or more here.
