An article on MobileMag details some upcoming robots from Seiko-Epson that will use Bluetooth as a control mechanism.

The robots aren't going to be available to the public (unless there is a large demand for it), but will be showed at ROBODEX next month.

The robot's stats are impressive: it moves at 15cm/second, has zinc-air batteries, and weighs only 12.5g with the batteries included.
