Robotics and high-tech toy manufacturer TOSY has just introduced the mRobo Ultra Bass, portable speaker that doubles as a dancing robot. The battery powered mRobo carries two gigabytes of internal memory that enables a listener to store about 500 songs via a USB port. The mRobo Ultra Bass will morph from a speaker into dancing human form with a speaker once you press “play”. The speaker has the ability to produce bass at 40Hz. The mRobo tips the scales at 3.3 lbs, and will not be taller than 18â€ł in size. Unfortunately, the bot is still in prototype mode, but it’s expected to retail for about $200 when it launches during the fall of 2012.
