Fire Fighting Robot [Sketch]

[Fire Fighting Robot: Sketch]

My partner and I wanted to create a sort of a squizzing mechanism to put out the candle. In the process of brain storming we came up with the idea of a bird wings. The wings would be up in the air hanging (connected to the servo mortor) and once the MotorCar finds the candle, the two wings would come together and squiz the candle in between. However, we knew that it would require much power from the servo motor, which we were not sure how powerful was. Therefore, we decided to have one wing stay still and have the other wing move down and up to put out the candle.



The image above illustrates the idea of just using one wing, whose one end is attached to the servo motor hanging. It would travel the 10 feet hanging up as high as possible, and once the candle is placed in between the two wings, the servo motor would spin and drop the hanging wing. In order for the wing to drop reliably, we needed a supporting piece that would allow the hanging wing to come up vertically and not diagonally. Therefore, we decided to make a supporting piece that would stick out from the top of the MotorCar. This is shown in the lower right corner of the picture above.



I personally did not like the idea of side ways wings because it would look just weird. Birds fly forward and it would look so awkward if we made our design into a side way bird opening up and down only its one wing. Therefore, we decided to make our design into sea shells. The sketch above is a distorted sea shell design to fit the width of our MotorCar. So, the top and bottom of the sea shell would squiz the candle in between. The second picture is a simplified version of it. It has two small circular holes on the top. They are the string holes to connect it with the base piece.




The two images above are the remaining parts of our mechanism. The top picture is the base that will be placed on top of our MotorCar. It has two small circular holes and two rectangular holes. The circular holes will be used to hang the top sea shell, and the rectangular holes are where the supporting pieces (the bottom picture) will be puzzled in. There is a circular hole in the supporting piece for the teflon rod to go through. The string connecting the bottom end of the top sea shell and the servo motor will rest in between the supporting pieces. Therefore, we designed the holes in the supporting pieces to be tight fits.
