Robopod is a simple arduino robot that uses antennas to detect obstacles. Robopod's motors are controlled by an H bridge and powered by a nine volt battery. Robopods circuit is based on a breadboard for easy modification.
First download the pdf and open it up in Adobe Reader and press the print button. When the print menu comes up select "poster" under page size and handling; press print. Using a paper cutter or a knife and ruler cut off the excess paper using the crosses to align the ruler or paper cutter. Then tape the sheets together with scotch tape and roughly cut the shape out. Next cut a off piece of corrugated plastic slightly bigger than the template you just cut out. After that, tape the template to the plastic and cut on the outside lines with a ruler and knife. Then tape the template back on the piece you just cut out and cut half way through on the rest of the lines so the segments can bend along the cuts.
Start by folding the shell along the scored lines and tape it together. Then glue all the seams and score lines with hot glue except the bottom ones . Once the hot glue cools remove the tape and then cut along the bottom score line so that you have flat base and a top shell.
Step 4: The Base
First print off the pdf file at the bottom of the page and cut it out along the outside lines and tape it to the robot base. Next, cut the two small rectangles out of the base with a knife.
