This person created a pulley-actuated hand that is controlled wirelessly via a glove worn by the user.  The project uses flex-sensors (which have a building tutorial included) mounted on a glove that a person wears.  When a person bends one of their fingers, the signal is processed by an Arduino Uno and then sent to a robotic hand with a nRF24L01.  This signals then sent to a reciever which is attached to another Arduino Uno.  The second Arduino activates servos that actuate the fingers.

I was particularly interested in the method of converting the physical movement of the person to an analogous movement with the robot.  There is much research being done into creating human augmenting robots, but I have never really considered the possibility of having the robot controlled remotely by actual human movements.  I wonder if haptic feedback could be added to something like this by looking at resistance of the servos somehow.  This could, perhaps, be done by recording the speed or drawn current of the servos.  I also believe for any practical uses, a more refined actuation method is necessary: controlling each joint individually.  There are a wide range of applications for a similar control method.
