[Fire Fighting Robot: Setup]
For our fire fighting robot, we implemented four sensors, two on each side. Sensors 1 and 3 are on the left side of the robot, while sensors 2 and 4 are on the right of the robot. Sensors 1 and 2 are the front sensors. Sensors 3 and 4 are the back sensors. We also added some Lego parts on top of our MotorCar so that we could attach to-be-cut delrin parts of our design later. We also had the servo motor hooked up to our Lego chip all ready to go!
[Fire Fighting Robot: Modeling]
We made our ideas into a model using the foams and basing on the sketches we had. The pictures below show our model. The top shell would have six holes in total, four in the front and two in the back. The four holes in the front help keep the balance of the top shell piece when up in the air, hanging from the string. The back two holes allow the top shell piece to be hanging from the base piece.
We knew that pinching the candle light in between the two delrin cut pieces would not extinguish the candle light but rather would start a fire. So, after a few hours of brain storming together, we came up with the idea of using a wet sponge in between the shells. Thanks to Lyn, he was able to get some colorful and pretty sponge for our robot!
[Fire Fighting Robot: SolidWorks]
Here are the three pieces for our fire fighting robot. They were to be cut from delrin, using the laser cutter, so we produced them in SolidWorks. They are exactly how we envisioned them in sketches, although the sea shell piece does not really look like a sea shell. Printing the parts out, we encountered some difficulties. Our first try was a failure because it printed the tiny stars in SolidWorks sketches. Also, it cut the lines that were different from the drawing (especially for the sea shell piece). We found out that it was because the sketches were either under-defined or over-defined (it showed red and gray lines for outlines of our drawings). We fixed the problem just by re-defining every dimensions, using smart dimension. Then, we were finally able to get our parts printed out!
