The above quick link will drop the reader into the controllers section where these boards are documented. The size and shape of these boards can clearly be seen outline in the design below.

Most of this work has been absorbed into the Small Bot Rev:2 project.

Following the reader can see the base design that all of the above flowed from. Clearly visible are the CCD camera from the laser range finder prototype. Also visible are the mounting of the sensor boards vertically at the top and bottom which each contain four distance sensors and the drive electroncis for the associated optics. Under the controllers section to the left, near the bottom the reader can find out more for the legacy board designs of the small robot.

Note also the tang sticking down from the right bottom. This has adjustment screws to hold a small laser line generator below the battery compartment. (batteries are mounted sideways)

Following the link to the right the reader can go to the files section of the web site where a 3D DXF file of this legacy small robot design is available for download.

Of course in looking through the CAD images above, the reader can see a number of PCB assemblies. It takes a bit of work to get all of this stuff to line up between the mechanical CAD and the and the layout CAD. Some of those boards can be seen, detailed, below.

To learn more about these check out section in controllers to the left.

Notice how the different colored connectors line up with the standoffs between the boards. The RED connectors are stack through the BLUE are for ribbon cables

The layout was complete before I stopped working this one, so I'll go ahead and present the artwork (below).

Oh-yeah, that last one that I didn't discuss above, is a power supply board. It takes input from the two gel-cells and generates the clean 5VDC & 9VDC to run everything here. It's an old design using a pair of LDO linear regulators. Were I to do it all again, I'd use a high efficency switching design.

Okay, this one is not almost done. It's more realistic to say that the left over pieces of this project have been absorbed into Rev:2 and that the few mechanical components that didn't fit into that project that have already been fabricated will make nice trophy pieces in my toolbox =)
