Give a child a toy and they're happy for an hour.
Teach a child how to make their own toys, and they're happy for life!



You learn the chip PINs NOT the programming board PINs!


Lesson 00 Power IN

JP20 is tied directly to the Battery IN V+/Vin male header of RoboGuts™ circuit board at JP18

Project X0 = Singing 'n Dancing miniFloppyBot


Click on the picture above to see the programming code

Body box, 2 Wheels, Top, Skid and Face ... the whole kit can be 3D printed on most printers in one day.

Learn how to build the bots

B.0 = RWheel, B.1 = LWheel B.7 = Red LED, B.6 = Green LED, B.5 = Blue LED C.0 = Talk & Song

ALL the .STL part files are waiting for KickStarter campaign to be funded.

Project X1 = Cave Explorer miniFloppyBot


Body box, 2 Wheels, Top, Skid and Face ... the whole kit can be 3D printed on most printers in one day.


Only 1 rubber band on 1 wheel for traction is why the bot
falters a little in the normal programmed operation,
but it is easily seen how the program works in the demo video.

ScardyBot ... Turns to Run Away
increase the turn radius of X0 closer to 180° to run away

ScardyBot ... Turns to Run Away
increase the turn radius of X0 closer to 180° to run away


Flip the direction and now you have a Psuedo SumoBot that goes after whatever is close!

Finds something in range and tries to stick to it like a poopie on your shoe!


Project X2 = PIXYbot

The PIXYbot is a miniFloppyBot with a RoboGuts™ and a PIXY CMUcam5.
The bot sees a color, displays the color in its body 3-color LED and speaks about the color it sees.

. . . . . . . . . . The one caveat to this is you need to have good lighting and bright colors for this sensor to see and
. . . . . . . . . . recognize colors correctly. Color lights and bacck-lit objects do not work with the PIXY CMUcam5.


Project X3 = Skully ... The Head of the Grim Reaper

A Skull that moves its Jaw and Turns its Neck while it Talks

Project X4 = Build a BillyBot Talking, Singing & Dancing Robot




Easy to build other than painting the parts and soldering up the audio amplifier PINs.


The RoboGuts™ are so simple!

B.0 = Neck, B.1 = RArm, B.2 = LArm, B.3 = RWheel, B.4 = LWheel
B.7 = Red LED, B.6 = Green LED, B.5 = Blue LED
C.0 = Talk & Song

Project X5 = Build a miniFloppyBot with OLED Eyes

Designed for the PICAXE 28X2 module with enough memory for all the movements, although smaller chips can still make movable eyes.


Project X6 = R2Pv1-OmniRover1
