The Marcbot IV-M, from Applied Geo Technologies, started out more or less as a remote-controlled car. It's built in large part from COTS components--that is, commercial off-the-shelf goods--including the servos, lights, antenna, and even the RC car itself. Getting robotics companies to use standardized and COTS parts will be important in keeping costs down.
