First, insert four rechargeable AA NiMH batteries in the four battery section of the battery compartment. Then, insert the battery cover to complete the assembly (Figure 6.27):

Now you're ready to control the Romi Robot with the hand-held Robot Controller.

Press and hold the push button on the Robot Controller to move the robot in four directions:

  • FORWARD
  • BACKWARD
  • LEFT
  • RIGHT

Of course, the DC Motor driver doesn't actually know if the gear motor is FORWARD or BACKWARD, so if you want to change which way it thinks is forward, simply swap the two wires from the motor to the DC Motor driver.
