Over the period of Mar. 26 – Apr. 16, team 36 started conducting the validation tests. Before the validation  tests, final adjustments to the Arduino code for the servo motors and the IR flame sensors were made. The team calibrated all four flame sensors and tested them numerous times with  fires placed at different positions in front of the device. The  t eam also used an aluminum epoxy bond to seal the gaps  in the aluminum outer shell. Team 36 then conducted the validation tests.  After the validation tests, the team spray-painted the outer aluminum shell and the device black for its final look. The following figure is the final stage of the Autonomous Firefighting Device and Team 36: For the device evaluation, the team sought to ensure that the device met the problem statement needs of identifying the presence of a stove fire, alerting of the fire’s presence, and extinguishing the fire source. To do these two validation tests were conducted. The first v...

Progress On Device Build and Upcoming Validations

Over the period of Mar. 6 – Mar. 26, team  36  started   with  mounting  the electrical  components  onto the pegboard. A figure was drawn to come up with the best placement of the components.  A   9V battery  that supplies the Arduino board with power  is placed above the air blower. The Arduino  b oard, the Relay Switch Module, and the  b readboard were all  permanently  fixed onto the pegboard .   T he wires were regrouped  and taped together  to ensure that they did not get in the way of the nozzle movement .  The plastic tubing was permanently fixed and sealed with the air blower to prevent  leaking of air.  The figure below shows the final build of our firefighting device ,  which has all the electrical components mounted on the pegboard :     Figure 1: Final internal build set up After all the components were mounted on the pegboard, the team then adju...
