Walk and chew gum at the same time!

This is the robot we featured in our advertising for a while.
You may recognize it as our Home Center robot with a face and
Halloween teeth added. It was a simple upgrade using a servo and some
plastic. Driving the servo for the lower teeth is as easy as plugging it
into the Co-Processor board. We were only using two servo channels and
there are eight available. Still five channels left. Imagine
what can be done with a few mini servos? How about a shrunken
Herbert or maybe some arms? Using a
timer makes the code simple. The Home Center Robot uses our Co-Processor on an AppMod board. The main processor board is a Parallax Board of Education. We now have a low-cost PCB kit you can buy to make adding our Co-Processor easy. Instead of connecting to the AppMod connector, it fits under the processor board. It will fit under either a Board of Education or a Parallax Toddler board. Here is the schematic. |

For more detail on the Home Center robot base, click
here. Here is a rear view. Hot melt glue was used to hold the top bridge and head onto the base. The upper teeth are attached using a piece of music wire hot melt glued to the bridge. The lower teeth are glued to another piece of music wire which is then glued to the servo arm. The teeth open and close as the servo moves. It isn't elegant but it was quick and it works. |

Here is a closer view to better show the attachments
for the teeth. It also really shows that the "gum" is actually a balloon. We never claimed it could blow bubbles and walk at the same time! |
