Batteries
29
ARobot’s controller board requires 9 to 12 volts supplied by 8 AA size batteries. We’ve found that the
best batteries are DuraCells. You can also use AA size rechargeable batteries. First turn the controller
board off and remove the battery pack from the battery cable. Install the 8 batteries observing polarity +
- which is indicated on the holder. Snap the cable back onto the pack and stick the pack to the body with
Velcro.
When the batteries get low, you will notice that the drive motor will be slow and erratic operation or re-
sets may occur. This will not harm the robot.
The power switch is located next to the power connector on the controller board. The ON position is
shown by a green dot. The OFF position is shown by a red dot. Make sure to turn power off when at-
taching cables, installing batteries, or installing the Basic Stamp or other parts.

Reset Button
The Reset button is located on the edge of the controller board near the Basic Stamp II. It’s used to re-
start the Basic Stamp II and the coprocessor which controls the motors. Reset can also be performed by
turning off the power and back on again.
