Controller Board
ARobot’s controller board is the brains of the system. It accepts a Basic Stamp II controller chip which
can be programmed from a personal computer. The controller board contains electronics used to drive
the motors, sound the speaker, control the LEDs, read whiskers, etc. An expansion port allows addi-
tional circuits to be added to the system.
The controller board is mounted to the robot body using 4) 1” plastic spacers and 4) 6-32 x 1/4 screws.
Place the controller board on the robot body and find the 4 holes that match the 4 mounting holes on the
corners of the controller board. There are 2 sets of mounting holes, select the set towards the robot's
rear. Install the 4 spacers in those holes. The controller board will simply snap onto these spacers and
can be removed any time. The 9 pin serial port connector should point towards the rear of the robot, the
expansion connector will be towards the front.
Summary:
Find 4 mounting holes on robot body. There are 2 sets, select the set towards the rear.
Mount 4 plastic spacers.
Snap the controller board onto the spacers.
