Here are connected motors that you can use to build robots and complete other fun projects. The Keigan Motor is a Bluetooth, brushless, and gearless electric motor with speed, position, and torque control. It is battery powered and has a 6-axis accelerometer-gyro. The developers are planning to introduce iOS and Android apps for these motors.
You can use more than one motor in unison to perform complex tasks. Since these motors have a flash memory, you can record motion and play them back. The developers are expected to release SDKs and APIs for these motors.
