Improve the power of a Board of Education and BoE-Bot

Start with your BoE-Bot - but then ...

The Parallax BoE-Bot is a popular BASIC Stamp®2 based hobby and educational robot. It even comes with excellent courses to get a starting roboteer going. After making the basic robot, adding more sensors or servos, or programming more advanced robot behaviors gets more difficult.

Step up to outstanding new computing power while still keeping the Stamp you know and love! Use our new low-cost PCB Kit to make adding our Co-Processor easy. See the Buy-a-Bot page to buy the Co-Processor, Bare PCB, or the complete kit. Mounting holes line up exactly so it fits directly under the Board of Education. Underneath mounting keeps the reset switch, and proto and AppMod areas accessible. Bumper and the vision parts on board clear off the top of the robot. Use of the Co-Processor gains several Stamp I/O pins. On-board LEDs to show the status of the IRPD system and the bumper hits. Get back Stamp programming room from expandable Subsumption control program variables and code. Three wire (servo style) A/D connections are perfect for Sharp GP2D12 IR distance sensors. Provides + 5V power, ground, and A/D input in one cable. Great for wall following! 8 servo controller connections for easy addition of gripper, camera pan-tilt, or sensor rotation servos, whatever! Frees the proto area for the next things you want to add! Use the same IR sensor and LEDs that came with your BoE-Bot. Plenty of room left to add some AppMod boards for even more expandability! It's Low Cost and Available NOW! Here is the schematic (2 pp - PDF - 23 KB). Because the Toddler uses a 4 cell supply, the kit comes with the Co-Processor Brownout disabled. Look at the discussion on brownout detection for more information. Here's the code listing as a text file.

<= Co-Processor Add-Under PCB.
	Left is a top view of the BoE-Bot with the Board of Education removed. The Co-Processor board contains all the connections needed for IRPD vision, bumper, A/D, and servo controllers. All on one easy to assemble PCB.

<= The wiring side.
	This side view shows the clean and simple wiring between boards. Only 3 power and 4 signal lines. Actually you don't even need that many if you don't want to use all the Co-Processor features!
<= Back View.
	Lots more free I/O for your use! On the left is the servo connector for channels 4 through 7. The right side connector is for servo channels 0 through 3. The left wheel servo is channel 0, and right is channel 1. The center connector is A/D 1-4.
