Construction of my robot continued today in class. At this point, I was a little bit ahead of my classmates, so I began construction of the body. As you can see in the following pictures, it consists of two levels of blue plastic with the board mounted on a separate level on the top. Provided are four pictures to allow for an overall look at its current state.
The pictures above and below show views of the front and rear of the robot. You should notice that there are some parts missing. These views allow you to see that the battery and bread board have not been attached yet.
The picture above shows the bottom, and the picture below gives a side view. The side view gives a good glance at the absence of wheels, motor mounts, and motors. All of these parts will be added as the project moves forward.
Once the majority of the body was constructed, there was a job to complete held over from the last class period. The wiring of the computer cord needed to be completed. During the last class period, it was established that the yellow, orange, and brown wires were needed. This was incorrect because I counted the ports from the wrong end of the plug. The orange was correct as number three (basically because the third hole is the same from both sides). Instead of yellow and brown being two and five respectively, it turned out red was two and green was five. In order to discover this miswiring, the Picaxe program was used to check our work. We ran a diagnostic program to check the flow of data. The program showed that no data was flowing. That was when it was discovered that the plug was read in reverse. Once that error was remedied, the diagnostic check turned out fine. The final step for today was to put a plastic plug cover over the wire ends. This is visible in the following picture.
Now the board is ready to be programmed. That will be next class.
