Last year I said that I would remove the Robot-specific code from the Robot Building kit app and sorry it took so long, but I finally had a week off of work, and took the time to make those changes. So starting with Robot-0.7.xx.zip, the Robots are completely separated from the Robot App. Robots are now loaded using a .Robot and other configuration files which define number of Ethernet PCBs, number of motors, accelerometers, touch sensors, motor-angle associations, 3D model of the robot, etc.  Now scripts can make use of the custom named robot motors and accelerometers (see the examples of TwoLeg and Rover robot in the Robot app "Robots" folder.
